Facilities Planning Department Upgrade Wastewater Treatment Facility Phase II South Jiddah Complex

1.0 PURPOSE OF FACILITIES

2.0

The purpose of the facilities is to support the corporate strategy of protecting the environment by providing additional industrial and sanitary wastewater treatment equipment to bring the South Iiddah Complex (SJC) wastewater discharge in full compliance with the Presidency of Meteorology and Environment (PME) and Saudi Aramco Engineering (SAES) environmental standards.

PRESENT SITVA TION

Presently, the industrial wastewater treatment plant (IWTP), located at the SJC Marine Area, discharges into the Red Sea wastewater that does not comply with contaminant limits set forth by PME regulations as determined by EPD assessments, documented in the Environmental Master Plan The SIC IWTP receives wastewater from three facilities - the Ieddah Refinery process unit, the crude and product tank farm, and adjacent Luberef. The existing IWTP, installed in 1982 and designed only to remove oil, grease and suspended solids from industrial wastewater, has become obsolete, deteriorated, and the treated wastewater calmot meet current environmental regulations for direct discharge to the sea. In 2008, a new IWTP, provided by ER- 10-03563 Upgrade Wastewater Treatment Facilities, Jeddah Refinery Complex - Phase I, herein referred to as Phase I, will replace the existing IWTP to treat industrial wastewater from these three facilities for the removal of oil, grease, and suspended solids within the limits set forth in the current environmental regulations for direct discharge to the sea, but will not bring the SJC in full compliance. A Phase II project (i.e., BI-IO-00473) is required to remove unacceptable levels of dissolved organic and inorganic contaminants from the Phase I wastewater effluent. Project phasing strategy was adopted by management in 2004 to reduce capital cost and allow for future expansion or modifications to the wastewater treatment facilities to accommodate potential changes in the operations of the SJc. In January 2007, management approved FPD's recommendation to discontinue the Jeddah Refinery operation of the fluidized catalytic cracking Wlit (FCCU) and platfon11er and continue the operation of the crude distillation and vacuwn units in a topping mode to produce fuel oil and asphalt as long as the Kingdom fuel oil balances are in deficit and JR high sulfur diesel can be supplied to the local power plants. As a result, the refinery will begin to operate as a topping unit in 2010 and the FCCU and the platformer unit will be shutdown Any proposed Phase II wastewater treatment facilities are to be based on such an operating scenario.

Several existing conditions and practices relating to the existing Jeddah Refinery process units and crude/tank farm areas will present challenges to the selected IWTP process that will be used to treat the industrial wastewater to fully meet current discharge standards.

• Current water draw-off practices of settled water in storage tanks in the product and crude tank farm areas allow extraordinary amounts of crude and product directly into the sewer system. Large quantities of crude and product in the sewer system result in performance problems and upsets in the IWTP.

• Seawater coolers in the process units are periodically backflushed with seawater, which is directly disposed into the sewer system. Depending on the IWTP process that is selected, the introduction of seawater, due to its high total dissolved solids content, would result in upsets in the IWTP.

• High temperature discharges from process units directed into the sewer system may upset or damage the selected IWTP.

The Jeddah Refinery sanitary sewage system, installed in 1977 and originaliy consisted of multiple area underground septic sumps (tanks) for anaerobic treatment, has not only deteriorated, but can not function as

BI-10-00473 DBSP 4 June 2007


designed. Sanitary sewage wastewater is now collected in these septic tanks, and hauled periodically by vacuum trucks to Saudi Aramco's AI Rehab community center in liddah for treatment or to a municipal dumping area for disposal. This hauling practice contravenes current environmental regul ations that require onsite treatment for large facilities. Many of the sanitary sewer lines are corroded and pumps are inoperable.

The instrumentation and control system of the existing wastewater treatment facility in the Marine Area is based on hardwired conventional instruments. The Phase I project will replace the existing main control panel located in the existing wastewater treatment control room with a new Distributed Control System (DCS) with a PC based Operator Station and Engineering Workstation. Some spare terminations and space have been provided for future Phase II .

Phase I will utilize the majority of the available spare capacity for its new loads in the existing RB I & RB2 MCC units at Substation RB located in the wastewater treatment plant in the Marine Area. Any significant power requirements for Phase Il work would require the construction of a new substation in the Marine Area.

3.0 LOCATION ANALYSIS

3.1 LOCATION OF PROJECT SITE

Saudi Aramco's leddah Refinery is located on the Red Sea coast in the city of l eddah, Saudi Arabia. The majority of the new BJ-IO-00473 (also referred to herein as Phase II) oily wastewater treatment facilities will be located within and adjacent to the Phase I oily wastewater treatment plant area of the leddah Refinery. Some of the work will be within the refinery process units and tank farm areas of the l eddah Refinery. The location of the new crude and product skim tank systems in Tank Farm Area utilizes existing contaiIUnent areas. Location of equipment shall be optimized during Project Proposal development and detailed design. See Figures I & 2 in the Appendix 15.2 for the overall plot plan of the l eddah Refinery and Marine Area that also indicate the major work areas for Phase II. Figures 3, 6, 8A, 8B, 8C, ll A & li B in the Appendices 15.2 provide more detailed location for the Phase 11 proposed equipment.

3.2 ROADS, ACCESS, AND LAND USE

The majority of the work for this project will be in the Marine Area of the l eddah Refinery and access is via a road patrolled by both Saudi Aramco security and the Saudi Coast Guard. In addition to standard Saudi Aramco plant [Os, persolUlel entering the Marine Area are required to obtain a separate gate pass issued by the Saudi Coast Guard that may take up to several days to process. Working within the main leddah Refinery area is accessed via the main pl ant gate with standard Saudi Ararnco plant IDs. The adjacent goverrunent port facilities can be used for receiving imported materials required for the project.

No Land Use Permits will be required as all work associated with this budget item at the SIPC are within the existing securi ty fence andlor covered by existing permits for work extending outside the securi ty fence.

4.0 INTERFACES

The proposed facilities shall interface, and engineering work for this project shall be coordinated with, facilities being constructed in the related budget items, as summarized below. To the extent possible, any physical tie-ins shall be made without materially affecting plant safety or operations.

4.1 RELATED BVDGETITEMS

ER-I0-03653 Upgrade Wastewater Treatment Facilities, Jeddah Refinery Complex -Phase I

This budget item provides for the upgrade of wastewater facilities at the reddah Refinery Complex to comply with the current environmental standards by instaning new IWTP facilities for the removal of oil, grease, and total suspended solids. These IWTP facilities, designed to handle 1450 gpm wastewater from the JR Complex, include, a new elevated API Separator, new Skim Tanks, new Walnut Shell Filters, and associated transfer pumps in the vicinity of the existing IWTP. A new Oily Water Lift Station will be required to consolidate the untreated wastewater streams for transfer to the elevated API Separator. This project will also install associated firewater mins and protection devices, inter-connecting piping, civil works, electrical gear, and distribution control system (DCS) instrumentation required to operate the new IWTP. The existing holding basin will be retrofitted with new stonn water pumps and supplemented with a new storm water/off-spec tank to provide surge for contaminated storm water prior to treatment. The existing API Separator will be modified and reused for sludge collection, and the remaining existing equipment will be demolished or abandoned in place. ER-1O-03S63 is Phase I and BI-00473 is Phase II of a two-phase project required to fully comply with the direct discharge standards. BI-10-00473 will furthertreat the wastewater discharged from the (ER-1O-03653) Walnut Shell Filters. Refer to Appendix 15.1, Dwg. Nq. V A -444454 for the

BI-10-00476, Upgrade Stormwater Drainage - South Jiddah Complex

This budget item provides for the upgrade of the storm water drainage system at South Ieddah Plants Complex (SJC) to provide safe and reliable operations. The project will upgrade the storm water drainage system at six storm water lift stations in the vicinity of the Tank Fann area. The scope of the project also includes installation of a new stonn water collection network at North AI-Nojoum Roundabout and Refinery Road No. 15 junction, Fire Station, Main Gate Station I and 2, Material Supply Office Gate, Asphalt loading Gate and Marine Area Main Gate. Moreover, the scope wi ll include regrading approximately 7000 square meters of roads in the southem portion of the refinery and around tile retention basin. BI- 10-00473 will require to coordinate and schedule with BI-IO-00476 the construction activities as both budget items may be working in common sites at the Tank Fann area. ERA: 4/10; ERC: 12/12

PROJECT PHYSICAL INTERFACES

Primary interface for this project wi ll be the installation of new wastewater treatment equipment downstream of tile equipment, specifically at tile outlet of the Walnut Shell Filters, which will be installed by ER- 10-03563. Wastewater from the crude and product tank farm areas will be routed to new skim tanks prior to being transferred to the Phase I wastewater treatment equipment. Existing heat exchangers that are back-flushed with seawater into the process sewer will require re-piping to route the seawater to the seawater cooling water return system. The gravity sewer discharges from Zone II (CDU#2, SGCU, and VDU#2), for Zone 3 (MEROX and Amine Units), and Zone IV (CDU#3, CDU#4, and CDU#5) of the Jeddah Refinery will require cooling prior to being sent to the Phase II IWTP. New sanitary sewer lift pumps will replace existing pumps or added on existing septic tanks and new pump discharge lines will be routed to irrigation pond. Installation of firewater protection devices for new Phase II IWTP can be made by extending the firewater headers installed under ER- I 0-03563 and ER-IO-03552. Existing plant and instrument air, potable water, and seawater cooling headers can be used to provide requirements for the new facilities. Primary electrical power supply shall be obtained for existing Substation R in the Marine Area and avai lable substation/sources in the Refinery and Tank Faml areas. Primary interface for the Di stributed Control System will be at the Wastewater Treatment control room in the Marine Area. Physical interfaces are indicated on the process flow schematics and plot plans in Appendices 15.2.

4.3 PROJECT OPERATING INTERFACES

Minimal interruption or shutdown of the Phase I I WTP equipment and other existing equipment is expected when Phase II tie -ins are required. Momentary shutdown of some process heat exchangers will be required to re-route backflush connection into the cooling water retum system. Sewage pits, requiring pumps and bar screens need to be added, will require sections of the pit be isolated to facilitate such modifications and continued operations. Shutdown requirements will be detennined during project proposal and detailed design development as described under Section 10.0 of this DBSP.

4.4 DEMOLITION ACTIVITIES

The following equipment in the Marine Area shall be removed by this project. This includes, but not limited to the following:

I. Existing Sand Filters (Y54-D- r A thru E), associated chemical addition tanks and pwnps, and backwash tank and pumps

2. Flocculator (Y54-D-5) and Compartment (Y54-D-2) 3. Thickener (Y54-D-I 4. Centrifuge (Y54-D-3AJB) 5. Thickener Feed Pumps (Y54-G-20AJB) - already partially demolished 6. Centrifuge Feed Pumps (Y54-G-21 AJB) - already partially demolished 7. Backwash Wastewater Basin (Y54-D-4) 8. Other equipment noted in Figures 14 and 16 thru 18 in Appendix 15.2

The site for the above equipment items , which are not currently in service or will not be in service post-BI-IO-03563, shall be cleared of all associated aboveground piping, structures, foundations, etc. to allow space for new equipment installed by tins project. Unless complete removal is required for the installa tion of new equipment, existing buried piping, structures, and foundations shall be removed to a level minimum 300nun below grade and the remaining portions abandoned in place. Figures 14 and 16 thru 18 in Appendix 15.2 indicate the general location and details of the abovementioned items required to be demolished.

Existing underground firewater piping at the site of the new Phase II wastewater treatment equipment may require demolition, in part, to accommodate installation of new equipment and new area firewater mams.

Each of the existing sanitary sewer sumps (ST-OI thm ST-07 and tank fanm) consists of oxidation compartments filled with packing and digestion compartments. All solid build-up in each of the digestion compartment and rocks (packing) in each of the oxidation compartments and shall be removed and disposed in approved landfills. Any existing partition or baflles may be removed if they serve no purpose. In some sumps, existing petitioned compartments could be bypassed as volume of the sump could be reduced as these swnps will function only as lift stations in lieu of being selfcontained treatment stations. Existing submerged pumps (two per sump) shall be removed. The existing sanitary wastewater lines between the lift stations and the irrigation pond shall be abandonedin-place or removed if it interferes with the installation of the new lines. A typical existing sanitary sewer sump (ST-OI thru ST-07) is shown in Figure 13 Appendix 15.2.

5.0 DESIGN OBJECTIVES

The overall design objective cf this project is the to provide the necessary lWTP equipment for the removal of organic and inorganic contaminants from the SJC industrial and SJC (excluding Luberef) sanitary wastewater within the limits set forth by PME and SAES direct discharge standards. The SJC industrial wastewater will have already been treated for the removal of oil, grease, and suspended solids from the wastewater within the limits set forth by PME and SAES direct discharge standards under the Phase I IWTP project.

BI-I 0-00473 DBSP 8 JUlie 2007

Facilities Planning Department Upgrade \Vaslewater Treatment Facility Phase II South Jiddah Complex

The new Phase II IWTP in the Marine Area comprises of the following major elements to achieve the overall design objectives:

• New API Separator, designed for oil and solids removal of the incoming wastewater, will provide additional capacity and meet sparing requirements. (Phase I excluded the required second API due to the uncertainty of the future operation of the Jeddah Refinery process plants).

• New equalization tanks, receiving a mixture of treated water from the Phase I IWTP and screened sanitary waste sewage collected from the SJC are designed to equalize flow into the next treatment step.

• New membrane bioreactor (MBR) units will treat the combined wastewater from the equalization tanks for the removal of organics and inorganic contanlinants. The treated wastewater from the MBR is discharged to the Red Sea via the existing lagoons.

The following requirements complement the operation of the new Phase II IWTP:

• New crude/product skim tank systems , installed in tile tank farm Areas A & B, are designed to allow secondary settlement of bottoms water drawn from crude and product storage tanks and also to ensure, via the installation of interface controllers, that only settled water is discharged into the gravity sewer system and the crude/product is recovered. Minimizing crude and product in the sewer system would mitigate any upsets in the wastewater treatment facilities.

• New retro-fitted pping associated with the existing seawater coolers in the process units is designed to ensure backflushed seawater is routed into the seawater cooling return line (rather into the sewer system).

• The new seawater cooled heat exchangers, installed in specific areas of the Jeddah Refinery, are designed to ensure that high temperature wastewater streams discharged from operating process units are cooled to required temperatures prior to discharge into the sewer system.

• Additionally, new sumps, piping and lift pwnps are designed to allow sanitary sewage to be collected from the various septic sumps and tanks located within the Jeddah Refmery including the Tank Farm, accumulated in the existing irrigation sump, and then transferred to the Phase IJ industrial wastewater facilities for treatment. Existing sewage pits that remotely located and/or considered to generate low volumes of sanitary waste will not be provided with lift pumps and piping; these pits will be continually be evacuated by vacuum tankers and hauled to nearest new Phase IJ sanitary sump/pit or Phase IIlntennediate Sump.

• The adequacy of firewater system, the capability of detection system and the required fire proofing for equipment structures will be considered for phase II IWTP to ensure proper protection of new equipment

6.0 GENERAL PROJECT DESIGN BASIS

The design basis for this project is established by the physical and chemical characteristics of the effluent discharged from the Phase I wastewater treatment equipment, the SJC (excluding Luberef) sanitary wastewater, and the design parameters described in SAER-6129 "Membrane Bioreactor (MBR) Treatability Study."

The current quantities of water draw-off from crude and product tanks are provided in Figure 19 in Appendix 15.2. Two skim tank systems, one for Tank Farm "A" and one for Tank Fann "B," will be provided and the basis for sizing the skim tanks is described in Ole aforementioned figure.

New Coolers for Jeddah Refinery Topping Unit Wastewater

The new MBR unit is designed to operate with a biomass thriving at temperatures less than 95 OF. As such, some of the wastewater streams being generated by specific process units will require cooling prior to di scharge into the gravity sewer system. No specific temperature infonnation is available for the wastewater being discharged from these process units. For design purposes, the average temperature of 120 OF is specified for the wastewater from these process units. The installation of seawater coolers at these process units is intended to cool the majority of the higher temperature wastewater streams. Maximum Inlet seawater temperature is specified to be 87 OF and tile outlet seawater temperature should be limited to 11 5 OF. Due to the existing piping layouts, other high temperature wastewater streams in the process areas may not be cooled; however, it is expected that the total mixed wastewater stream to the wastewater treatment facilities will be on average less than 95 OF.

New Sanitary Wastewater Collection System

Approximately 45 M/day (12,000 gallons/day) of sanitary waste is being collected via vacuum tank trucks from 39 sumps scattered throughout the Jeddah Refinery and Marine Areas. Considering peak usage, the overall maximum design fl ow of I 15 M3/day (30,000 gallons/day) is specified.

7 .3 NEW WASTEWATER COOLERS

New Coolers shall be provided by this project to cool the wastewater from the existing Jeddah Refinery topping process units to being disposed into the gravity sewer system. These coolers will ensure that the temperature of the wastewater in the MER system is maintained at less than 95 OF. Three cooling systems are being proposed - one for Zone 1I process area (CDU#2, SGCU, and VDU#2), one for Zone III (MEROX and Amine Units) and one for Zone IV process area (CDU#3, CDU#4, and CDU#5). For each zone, two new self-priming 23 M3IHr (100 gpm) each Wastewater Transfer Pumps shall be provide to draw (regulated via level control) wastewater from hdividual existing area manholes and pump the wastewater through a new plate and frame type s,awater Cooler and then into subsequent existing manholes. Under high flow conditions (rain or firewater) initiated by level indication in the manholes, the wastewater transfer pumps are bypassed and the wastewater is' directed from manhole to manhole via gravity. During high /low, the wastewater combined with rain or firewater would not require cooling. The general location and overall process flow for these coolers are shown in Figures 8A, 8B, 8C & 9 in Appendix 15.2.

It should be noted that the installat ion of the new wastewater coolers requires that a valve box be installed that will contravene the requirements of SAES-B-008, para. 5.2. Preliminary review by Loss Prevention (See E-mail of April I, 2007 in Appendix 15.2) indicates that the acceptance of the design providing that all of the requ irements of para. 5.2 (exceptions) of SAES-B-008 (I through 6) shall be complied with and implemented. Also, drawings shall be submitted during Project Proposal development to Jeddall Area LPD for review and the installation of the proposed heat exchanger & pumps.

8.0 SCOPE EVALUA nONS TO DATE

8.1 MBR SYSTEM

The MBR technology, which introduces powder activated carbon (PAC) upstream of the MBR membranes, is being selected on the basis as being the most cost effective alternative for treating the wastewater for the SJc. Three other treatment processes were previously evaluated:

I. Conventional Dissolved Air Flotation (OAF), Activated Sludge Treatment (AST) - cylindrical clarifier with sludge rake, and Filters - Using this system would have required the addition of granulated activated carbon columns downstream of the clarifiers so that PME compliance of the treated wastewater can be met. In addition, considerably more equalization would have been required. Replacement of spent carbon would have been costly if such a system was implemented. Reliabi lity and feasibility are questionable and as such, lead to the development of the physical chemical treatment system described below.

2. Physical Chemical Treatment - This system uti lized a resin to remove phenols, an air stripper to remove anmlOnia, and granulated activated carbon to remove all other contaminants at levels in compliance with PME regula tiollS. The system was operationally simplistic, but required a multinlde of unit operations. Though pilot testing continned that the innovative technology is feasible, no commercial faci li ty has been installed. Routine replacement of spent resin and carbon would have been costly if such a system was implemented.

3. Conventional MBR - Similar to Ule conventional DAF/AST described above, conventional MBR would have required the addition of granulated activated carbon columns.

)

Facilities Planning Department Upgrade \Vastewater Treatment FacilitJ Phase II South Jiddah Complex

The PAC for the proposed MBR system is utilized as an aide to the treatment process. However, the quantity of carbon (PAC) used is significantly less than that of the conventional MBR followed by GAC columns.

8.2 SANITARVSEWERSVSTEM

The existing Jeddah Fefinery and Marine Area contains 39 sanitary sewage sumps/pits that are normally emptied by vacuum tank trucks and is hauled to Saudi Aramco's Al Rehab community center in Jiddah for treatment or to a municipal dumping area for disposal In lieu of installing piping and pumps to allow all sanitary sewage pits to be transferred to the new Phase II wastewater treatment facilities, only selected sewage pits, which are currently emptied via tank trucks every one to two days , were provided with such capabilities. In general, sewage pits that generate low volume of waste and/or are remotely located were not provided with piping and pumping facilities. These pits will continue to be emptied via vacuum tank trucks, with the exception that the collected sewage will be hauled to the nearest new Phase II sanitary sewer sump/pump or new Phase II Intermediate Sump.

8.3 ELECfRlCAL POWER REQUIREMENTS FOR MBR BLOWERS

The three new AerationIMOS Blowers for the MBR system are rated at 225 kW (300 HP). Per Aramco Standards, High Voltage (HV) power supply requiring an additional tTansfomler, HY switchgear, and associated motor controllers is speci fi ed for this application. The power supply for tile existing wastewater treatment facilities in the JR Marine Area is stepped down from 13.8kV to 400 V and there are no intennediate voltage levels. In lieu providing high voltage power supply, which includes HY switchgear and other associated HY equipment, it is proposed to utilize the low voltage 400V power supply with solid state reduced voltage controllers for the blower motors. Correspondence (See Appendix 15.2) from CSD has indicated support for a waiver, which is to be processed by PMT during Project Proposal development.

9.0 ADDITIONAL STUDIES DURING PROJECT PROPOSAL DEVELOPMENT

9.1 Bun.o, OWN, OPERATF, AND TRANSFER (BOOT) OR DESIGN BUILD OPERATE(DBO)

During Project Proposal development, FPD, PMT, and other Saudi Aramco organizations shall further develop and evaluate the economic merits for using a third party arrangement via BOOT or DBO to meet the objectives of the Phase II facilities. The evaluation should also include the operations and/or maintenance of the Phase I facilities with a third party.

9.2 SANITARV SEWERSVSTEM

Though selected sewage sumps and pits will be provided with Sanitary Sewage Lift Pumps, the project should consider further consolidating some of these sewer pits to minimize the quantity of Sanitary Sewage Lift Pumps, especially in the Jeddah Refinery area, during project proposal development. Depending on location and hydraulic prome, (an) existing sanitary sewage pits could be modified to gravity flow into another existing pit, where sanitary sewage lift pumps are to be installed.

The location of the grit chamber and drum screens are currently shown to be elevated at the EQ Tanks . Alternate locations, such as placing such equipment at the Intermediate Sump Pit, can be considered if installation is more cost effective.

9.3 HYDRAULIC PROFILE AND ANALYSES

9.4

PMT shall conduct a detailed hydraulic profile and analysis of the new oily wastewater treatm ent (MBR) units during Project Proposal development to ensure that the system flows are me~ especially those units that are dependent on gravity flow . In addition, the hydraulics in accordance with SAESB-017 for the firewater system should be verified utilizing infonnation available from ER-IO-03552 and ER-10-03563 (See above Section 4.0).

ENVIRONMENTAL IMPACT STATEMENT

An Environmental Impact Assessment (EIA), per SAEP-13, for the project shall be completed at the 30% or initial issuance of the project proposal review package and shall be treated as a primary design objective. EPD has cl assified this project as requiring a Category 3 Environmental Impact Assessment. The project enviromnental assessment shall detail the ambient environmental conditions before the project becomes operational. Wastes and pollutants generated in the construction and operation of the proposed facility shall be described in detail. The control measures and monitoring programs needed to meet the enviromnental protection requirements in the current Saudi Aramco Standards and GI's shall be specifi ed and explained. Potential environmental impacts that must be addressed in the ElA include, but are not limited to:

• Effluent discharged will comply with PME regulations, • Disposal of construction debris, • Disposal of the contaminated soils if any during the excavation,

• Disposal of the hydrotest water • Disposal of industrial solid and hazardous waste, if any, and

• Spills and other non-routine releases.

9.5 ELECTRICAL SYSTEM STUDIES

During the Project Proposal Phase the existing ETAP Model shall be updated and a power systems study implemented that includes analysis of loads, short circuit duty, load flow, voltage drop, motor starting, and protection device coordination settings.

10.0 CONSTRUCTABILITY AND LOGISTICAL ASSESSMENT

The new API Separator will be installed next to the existing Phase I API Separator. As pile -type foundations will be required, the project should ensure that the installation will not disturb the aligmnent of the Phase I API Separator. Coordination with the Phase I wastewater treatment project with respect to the addition of tie -in valves to existing tie- in points would minimize shutdown requirements.

For all other major Phase ]] wastewater treatment equipment in the Marine Area, the demolition of existing area equipment and the minor relocation of roads wou ld facilitate space for new equipment.

The installation of the rew crude/product skim tank systems in Tank Fann Area A and B at the proposed site will require the removal of soil contam inated with hydrocarbons. The existing abandoned elevated flare in the proposed location of the Tank Fann Area B Skim Tank System shall not be demolished by this project.

EXECUTIVE SUMMARY

Saudi ARAMCO is planning to construct a new access roads and a drainage system at their marine area in Jeddah Refinery at Jeddah, Saudi Arabia. The new access road will link the marine area east of API Separator to the existing marine roadway bridge inside the Jeddah Refinery. The proposed project will include upgrading the existing API access road and construction of a new pipeline access road . Fugro-Suhaimi Ltd. (FSL) was contracted by Saudi ARAMCO to perform a geotechnical investigation for the proposed access road.

The objectives of the geotechnical investigation were to explore subsurface conditions along the route of the access roads, and develop engineering recommendations to guide the design and construction of the access roads. The objectives were achieved by conducting field and laboratory investigations.

The field investigation comprised drilling 8 No. boreholes, performing 8 No. piezocone penetration tests (PCPT), excavating 3 No. test pits and obtaining samples for laboratory CBR tests from five locations. Boreholes were drilled to 5-m depth, PCPTs were performed to 5-m depth or to practical refusal whichever was shallower and test pits were excavated by hand tools, to depths of up to 1.5 m, or groundwater level, and samples were

. obtained for laboratory testing. In addition, asphalt cores were obtained at three locations along the existing API road.

Laboratory testing was performed to verify soil classifications, and evaluate the chemical and earthworks properties of soils encountered. Tests included sieve analyses, Atterberg limits, water soluble chloride and sulphate content, carbonate content, moisturedensity relationships , and CBR tests.

The subsurface soil conditions encountered along the API access road and the pipeline access road are summarized below:

Recommendations for fill placement and compaction are given in the report, and should be in accordance with Saudi ARAMCO Engineering Standard SAES-A-114. CBR tests should confirm compliance with Saudi ARAMCO Specification SAES-Q-006.

Recommended road embankment fill material are clean sand and or marl. Clean sand should be compacted to 85 percent of relative density and marl should be compacted to about 95 percent of the maximum dry density.

Because of the presence of very loose to loose subsurface soils at the site, consideration could be given to the use of geomaterials including geotextiles and geogrids for the proposed road constructions. Geomaterials are discussed in the soil improvement section of the report

Based on the laboratory CBR test results, our recommended CBR value for the existing site soils within a depth of 1.5-m from the existing grade is 30 when compacted to 95 percent of the maximum dry density. For bulk fill materials from suppliers, we recommend to perform CBR tests to confirm compliance with Saudi ARAMCO Specification SAES-Q-006.

Marl should be used to protect unpaved bulk sand fill against wind and water erosion. Fill embankment slopes should not be steeper than 1-vertical to 3-horizontaL

Surficial soils can be excavated using a large mechanical backhoe, or bulldozer. Excavations are expected to encounter groundwater. The slopes of excavations in soils should be limited to 1-vertical to 3-horizontaL

5.0 FILL PLACEMENT AND COMPACTION FOR ROAD CONSTRUCTION

5.1 General

We understand that the proposed access road will be constructed on fill embankments.

Important geotechnical considerations for construction of the access road will be:

• availability and type of suitable road embankment fill materials;

• road embankment fill compaction requirements, stability of fill slopes, and type of compaction equipment;

• excavation of soil in cut areas, including type of excavation equipment required, suitability of excavated materials for use as fill, and stability of slopes for road cuttings; and

• subgrade and base preparation, including design CBR values.

The following sections discuss fill materials and its compaction requirements and equipment used for backfilling. In general, fill placement and compaction should be in accordance with Saudi ARAMCO Specification SAES-A-114. The recommendations given in the following sections of this report are our site specific minimum recommended earthworks requirements. In the event project specifications specify stricter earthworks requirements than recommended by us, the project specification should take precedence.

5.2 Fill Materials

Fill materials required will include:

• Clean sand for bulk fill, required for general site grading; and

• Marl for bulk fill and capping unpaved fill, required for protection against wind and water erosion.

Sources of bulk fill are expected to be dune sand and marl.

Clean sand (bulk fill) should contain less than 10 percent passing the No. 200 (75 f'm) sieve.

Marl, where available, may also be used as bulk fill. According to Saudi ARAMCO Specification SAES-A-114, the definition of marl is:

" ... a wide variety of calcareous soil materials found in Saudi Arabia which may vary from clay to gravel sizes, and often includes cobble and boulder sized pieces ... "

In general, however, suitable marl should consist of material with less than 30 percent passing the No. 200 sieve. The minus 40 fraction should have a maximum liquid limit of 25 and a plasticity index less than 8.


Page: 11

The material for crushed stone bases and subbase for the pavement should confirm to Section 5.2.1 of Saudi ARAMCO Specification SAES-Q-OOS.

5.3 Site Preparation

Surficial deleterious material including loose soils and vegetation should be removed from areas to receive fill. In general subgrade surface should be prepared in accordance with the gUidelines provided in Section 5.1 of Saudi ARAMCO Specification SAES-Q-006. The natural soils should be tested and prepared prior to fill placement to ensure that the average in situ density is 85 percent of the average relative density (for clean sand), or 95 percent of the maximum dry density established from modified Proctor compaction tests (ASTM D-1557). Field density tests should be performed to evaluate the requirement for compaction of the surficial soils. The density requirements of subgrade surface should confirm to requirements of Section 5.1 of Saudi ARAMCO Specification SAES-Q-OOS.

5.4 Fill Compaction

Compaction of fill should be in ac.cordance with Saudi ARAMCO Specifications SAES-A-114. Below the road pavement fill should be compacted in accordance with requirements for structural fill. Actual compaction requirements will depend on the type of fill material (clean sand or marl).

5.5 Compaction Equipment

The procedures used for fill placement and compaction generally depend upon the material used and equipment available. A 10-ton vibratory roller is most suitable for compacting granular soils. Large quantities of water may be needed to facilitate compaction . The lift thickness that can be effectively compacted will depend on the gradation of the fill material. Lift thickness and compaction should be in accordance with Saudi ARAMCO Specification SAES-A-114.

5.6 Fill Slopes

For the purpose of stability, embankment slopes in soil should not be steeper than 1-vertical on 3-horizontal. Embankment slopes should be protected from wind and water erosion. A marl cap, minimum 150-mm-thick, compacted to 95 percent of the maximum dry density determined from modified Proctor compaction tests (ASTM D-1557) will probably be the most suitable type of erosion protection for road embankment slopes.

5.7 Cut Slopes

For the purpose of stability, road cUllings should be designed as follows:

Temporary Cutting in Soils 1-vertical to 1.5-horizontal

Permanent Cutting in Soils 1-vertcal to 3-horizontal

Report No. SA03-S002

Page: 12

Embankment side slopes should not exceed 1-vertical on 3-horizontal. All excavations trenching · and shoring should be done in accordance with Saudi ARAMCO Safety Manual Section 2.0.

5.8 Use of Excavated Materials

We expect that the existing fill material encountered in the boreholes and the test pits at the site can be used either as bulk fill, or marl for surface capping. The carbonate silty sand encountered in the boreholes below the fill material is not recommended for use as fill material.

6.0 PAVEMENT DESIGN AND CONSTRUCTION RECOMMENDATIONS

6.1 General

In the fOllowing sections general geotechnical design considerations for subgrade and base course design applicable to the proposed access road for this project are presented. We recommend that the design of the embankments for the proposed road be based on the results of laboratory earthwork tests, which should be conducted on the fill material for the access road .

6.2 Soil Improvement

Very loose to loose subsurface soils are present at the site below about 0.5-m depth. Improving the subsurface soils at the site by removal and replacement will include dewatering which could be an uneconomical solution. We recommend that the embankment for the proposed road be made of sufficient thickness to safely carry the anticipated loads without influencing or affecting the loose subsurface layers.

Consideration could also be given to the use of geotextiles and geogrids. The geotextiles will serve as a containment for the proposed embankment fill and the geogrids will serve as a reinforcement in the fill material. Most companies marketing these materials offer proprietary software for the design of earthworks systems incorporating geotextiles and geogrids and should be contacted at the detailed design stage for further information about the applications of these material and the design ' considerations. The construction contractor shall be responsible for selecting the appropriate and economical soil improvement technique. In accordance with Saudi ARAMCO Standard SAES-Q-006 the selection and design of soil improvement technique shall be reviewed by Saudi ARAMCO's consulting services division prior to implementation.

6.3 Subgrade

Natural subgrade should be prepared in accordance with the recommendations for site preparation given in Section 5.0 of this report, and compacted to at least 95 percent of the maximum dry density measured from laboratory modified Proctor compaction tests or 85 percent of the relative density measured from laboratory maximum and minimum density tests. The thickness of the compacted subgrade should be based on the expected loading conditions and should be in accordance with Saudi ARAMCO Specifications SAES-Q-006.

On the basis of laboratory CBR results, we recommend a CBR value of 30 for the existing onsite fill materials.

Subgrade design and the CBR values to be used in the design should be in accordance with Saudi ARAMCO Specifications SAES-Q-006. We recommend that CBR tests should be conducted on the fill material for pavement and the access road to confirm compliance with the referenced standard .

6.4 Sub-base and Base

We expect that fill materials consisting of marl will probably be used as sub-base and base course beneath pavements. Appropriate thicknesses for base course material should be selected on the basis of the design traffic and loading conditions anticipated for the new facilities plus consideration of the subgrade and base course CBR values.

Asphalt and concrete mix and thickness design for wearing surfaces is beyond the scope of this study, Care should be taken to grade roadway and parking areas to provide good surface runoff to drainage ditches, Wearing surfaces for roads and parking areas should be a dense mix nearly impervious to water in order to minimize infiltration of surface runoff into the base course ,

Waive VE Study for OHSP

Your concurrence is requested to waive requirements for performing a value engineering study during DBSP development tor the subject ·project. VE study requirements during DBsr development arc stipulated in SAEP-1350 for projects with an initial capital investment exceeding $50MM, unless Fro and PS&CD inutual'ly agree that a 'VE study is not warranled. The current cost estifilate for BI-l0-00473 is $6~MM. .

FPD has worked closely with Ero and a consultant in optimizing the design basis for the BI-IO-00473 DBSP and has detcTfilined that conducting a VE during project proposal would be more beneficial once the design has further progressed. The attached e-mail correspondencc bctween rS&CD, FPD, & EPD also provides other reasons fo r the need to conduct only one VE study for BI-10·00473.

Should you have any question, please contact Ali J('jshi at Tel. 875·6344 or John Yee at Tel. 873-008\.

J. Comments and Responses: During the meeting, all comments were discussed Info and resolved as reflected in the attached log of comments and responses, which will be transmitted with the final DBSP. Responses, where noted, will be incorporated in the final DBSP. All other responses in the attached table, including those not directly incorporated in the main DBSP document, shall form the basis for BI-IO-0473

Though the responses to the comments have been revised III the log as discussed in the meeting, the below items highlights some of the issues that were discussed at length or required additional follow-up. Post-Meeting notes reflect the final decision for comments requiring follow-up.

2. Feed Breaker Power Supply from Substation R (Comments Nos. 20 and SO): The spare breaker in Substation 'R' was being planned to be used for supplying power to the new BI-IO-00473 substation in the Marine Area based on a fi eld survey by FPD and JR. However, further investigation by the JR now indicates that this breaker has been reserved by #EWO-OSW228A, a project to install security lighting in the Marine Area. An alternative, suggested by FPD, is io allow BJ-IO-00473 utilize the spare breaker and have the security lighting project take power from the new BJ- 10-00473 substation in the Marine Area. In implementing this alternative, JR shall review with the Security Dept. on the schedule and load requirements of #EWO-OSW228A. If this alternative is not feasible, FPD and JR will require to determine an alternate power source for the new substation.

Post-Meeting Note: Per E-mail of June 6, 2007 (copy attached), the Jeddah Refinery has confirmed that the spare breaker in Substation 'R' is available for use for this project.

3. BI-IO-00473 Substation in Marine Area (Comment No, 21): FPD will clarify FPD whether the new substation will need to be blast resistance and reflect (Closed) requirements in the DBSP,

Post-Meeting Note: Blast Resistance construction is not required, However requirements of SAES-B-068, SAES-M-IOO, and SAES-P-119 shall be fully implemented.

4, Power Source for New Egui~ment in Tank Fann (Comment No, 25): WRPD FPD expressed a concern with the availability power in the tank farm area for the (Closed) new BI-1O-00473 equipment FPD indicated that a site survey has been conducted identifying potential existing substations where spare breakers have identified. FPD will forward this preliminary survey to PMT for infonnation only, as substation loading still needs to be detennined along with the need for an ET AP study during PP development

) Post Meeting Note: FPDIIT &E forwarded via e-mail to the JR and WRPD on June 3, 2007 the survey of available spare breakers/space in existing substations.

5, Existing Power Cables for New SanitarY Sewage Lift PumRs (Comment No, JR

l21 WRPD expressed a concern for the condition of the existing power cable (during PP for the sanitary sewage lift pumps. FPD stated that existing cables (especially development) low voltage) are considered to be in suitable condition unless testing indicates otherwise, However, it was agreed that the JR will take responsibility for checking their condition during PP development

6, Use of Low Voltage for 300 HP motors (Comments Nos, 32, 33, 49 & 51): FPD The current power supply in the Marine Area is stepped down from 13,8kV to (Closed) 400 volts, without any other intennediate voltage level. It proposed to use the 400 volt supply to provide power to the new BI-10-00473 300 HP motors, which would nonnally require to be supplied by a higher voltage level (3300V for the JR). Using the lower voltage will require a waiver to the SAES, FPD will obtain and include correspondence in the DBSP that will basically state that CSD will support a waiver for the proposed arrangement A waiver would then be required to be processed by PMT during PP development

Post-Meeting Note: CSD will support a waiver to operate the 225 KW motors at 400V. (See Email Attachment).

7, Project Schedule for BI-1O-00473 (Comment No. 31): WRPD stated that the Info current schedule cannot be achieved since more time is required to secure a project proposal contractor based on current market conditions, FPD indicated that the current schedule is based on the recent Table Top discussions with the exception of the duration for PP Start to ERA being 8 months instead of 10 months. FPD also stated that, if the PP can start in July 2008 rather than August 2008, then the duration would be 9 months, WRPD indicated that this would be still insufficient time to execute the project WRPD requests that the PP Start date still be August 2008 , but the ERA be July 2008 (in lieu of April 2008) and the ERC be February 2011 (in lieu of November 2010). The ERA-ERC duration (32 months) remains as per the Table Top discussion, The JR did not agree with the revised schedule unless the ERC remains November

20f 2

2010.

Post-Meeting Note: FPD further reviewed the above matter with its management. Project schedules are basically set forth by PMT based on what is truly achievable to execute the project. Therefore, the final DBSP will refl ect the above revised dates.

given during such project stage. Number of pumps and their sizes are given in DBSP which is normally provided in a later project stage (design stage).

I have reviewed this project BI- 10-00473 (Upgrade Wastewater Treatment at SJ Complex) via the link given below. This project is relevant to the same project being upgraded at Marine Area adjacent to API separator. We have conducted site visit to the area, and we submitted our operational comments to the PMT before starting the work, as the area of the project needs additional security measures. We don't have any additional comments from Technical Point of View, and we leave that to PCG for study and evaluation along with their findings and comments. On the other hand, the allocated budget incUded also BI-IO-00476 (Upgrade of Storm water Drainage System at JR Complex). We have already submitted our operational comments to Mansour Angawi to be included in the project. Anyhow, the DBSP approved and included our security gates in the project such as JR Main Gate # I , JR Computerized Gate # 2, MSO Gate # 7, Asphalt Gate # 4 and Marine Main Gate # 8. It seems most of the work will be inside the fenced area, but all SAES-O series standards should be implemented especially when there is some pipes crossing roads or fences. Also bathrooms and kitchens located at JR security gates should be considered and included in this project wastewater treatment. Thanks.

The soil investigation report attached in the DPSB is very old (1982), an updated test was conducted on 2003 (Report attached on E-mail), should be used in the design.

there are needs to match existing equipment or required to meet specific process conditions. Similarly, some of the equipment capacities will be removed. Requirements will be addressed by the PMT as required prior to construction.

Security standards will be implemented as required for any pipe crossing through security fences during Project Proposal and detailed design development. Since the security area gate generate low volumes of sanitary waste, their septic tanks will be continued to be emptied out by tank trucks. The tank trucks would then empty their content into the new Intermediate Sump at the new wastewater treatment plant inside the Marine Area. Agree. The 2003 report (excerpt only) will be included.

13.8 kV/480V XFMR 480 V Swgr. 480 V MCC SUbstation Auxiliaries Largest Loads - Three motor loads are rated a 225 KW (300HP)

:tandards call for these motors to operate at 4.16 kV. This voltage level is currently not available in the Marine .Area. There is urrently no other application or requirement for 4.16 kV in the Marine Area . In order to be cost effective, could it be proposed that lese motors operate at 400 V with NEMA Size 6 Starters. This would reduce the cost of the installation by eliminating 13.8KV :witchgear, 4 .16kV XFMR, 4.16 kV MCC's, DC Power System, and other associated components.

The site for the above equipment items, which are not currently in service, shall be cleared of all associated aboveground piping, structures, foundations, etc. to allow space for new equipment installed by this project. Unless complete removal is required for the installation of new equipment, existing buried piping, structures, and foundations shall be removed to a level minimum 300mm below grade and the remaining portions abandoned in place. Figures 14 and 16 thru 18 in Appendix 15.2 indicate the general location and details of the abovementioned items required to be demolished.

Existing underground firewater piping at the site of the new Phase II wastewater treatment equipment may require demolition, in part, to accommodate installation of new equipment and new area firewater mains.

Each of the existing sanitary sewer basins (ST-OI thru ST-07 and tank farm) consists of oxidation compartments filled with packing and digestion compartments. All solid build-up in each of the digestion compartment and rocks (packing) in each of the oxidation compartments and shall be removed and disposed in approved landfills. Any existing partition or baffles which Sumps shaH be inspected and any repairs required shall be carried out by this project. Existing submerged pumps (two per sump) shall be removed. The existing sanitary wastewater lines between the lift stations and the irrigation pond shall be

EXECUTIVE SUMMARY

We at Siemens would like to thank you for the opportunity to offer Siemens equipment and services for your waste water treatment needs as part of the MBR bench study projects on treating a modified Jeddah refinery wastewater and the Juaymah Gas Plant wastewater.

We understand the important nature of specifications, end user, schedule, engineering and management expertise, and process and mechanical reliability. Our experience with Saudi Aramco will help you finalize procurement, design, and construction of the waste water treatment systems on-time and onbudget. Our offer is compliant with Aramco redundancy, material and inspection standards and specifications, except where specifically noted.

Dependent on project timing, our project manager for this project will be Mr. Joseph Momont. Mr. Momont is not only one of our resident PM experts on Membrane BioReactors, he has recently executed two large orders for Saudi Aramco. He is familiar not only with Saudi Aramco specifications and Saudi fabricators, but also our ISO-9001 project management and fabrication requirements . He will ensure that equipment design, engineering submittals, fabrication techniques, and documentation are carried out per the project and ISO 9001 requirements.

Per SAES A-104, all of the equipment is designed for automatic operation (and automatic switchover) , will be skid mounted, pre-piped and wired, and shop tested wherever feasible .

The Petro™ PACT-MBR Membrane Bioreactor system has been designed with ease of installation and operation in mind.

We have already engineered solutions to meet the requirement for low maintenance, by reducing the amount of rotating equipment. Sludge wasting pumps have been eliminated through multiple duty with the MOS recirculation pumps. Membrane scouring blowers have been eliminated by sharing duty with the bioprocess air blowers-all of which reduce electrical/MCC and other infrastructure costs. We have also suggested alternates to the specifications, in order to minimize capital cost and lead time. In this fashion , we have addressed desire for quick installation, and the need for low maintenance, while supplying an Aramco-approved-Iow cost solution.

The current bench testing program has shown the conventional MBR system to practically remove all of the BOD5 from the Jeddah wastewater. However, COD removal has been marginal to meet PME marine discharge requirements. The Jeddah wastewater was found to be relatively difficult to treat, with a relatively long acclimation phase and lower COD removal than treatment with the PetroTM PACT-MBR, potentially exhibiting symptoms of bio-refractory or bio-inhibitory compounds in the wastewater.

We look forward to discussing our Petro ™ PACT-MBR technology with you in the near future. The following briefly summarizes the advantages of using the Petro™ PACT-MBR.

placed in the aeration tank - the Grease and Scum are in direct contact with the membranes. This results in a build up of scum in the membrane tank as there is no method of removal. Due to scum build up, if membranes have to be removed from the aeration Tank, this grease and scum come in direct contact with the membranes, and cause fouling . The Petro ™ MBR addresses this important design consideration using a vertical flow pattern in the MOS Tank-and uses overflow weirs to return the scum back to the aeration tank for further treatment.

2) The distribution of the mixed liquor is uniform in upward direction. The concentration of the mixed liquor is uniform in the flow direction-across the entire tank cross section. In other designs, where no mixed liquor distribution system is present, the MLSS concentration increases as the flow proceeds to the outlet. As a consequence, the efficiency of the membranes closer to the outlet is reduced-exerting more pressure on the other membranes to keep pace with influent flow. The Petro ™ MBR keeps the sludge viscosity equivalent on all membrane bundles-resulting in even duty and longer operationa l life for each membrane.

) 3) The energy requirement for aeration and scrubbing purposes is lower then in the systems where the membranes are placed in the aeration tank.

4) Membranes are automatically cleaning in-place in the separated MOS Tank. This requires little to no operator intervention, in comparison to systems that require membrane removal for cleaningor cleaning in an aeration Tank.

5) Siemens' patented two-phase jetting is utilized to ensure membrane bundles remain at peak permeability. With continuous cross flow scouring with both air and mixed liquor, all membranes operate in the same liquid viscosity-which means all membranes operate in an equivalent capacity. The end result is more water produced with less maintenance.

Today, Siemens membrane plants treat more than 3,750,000 m3/day globally in applications ranging from wastewater reclamation to drinking water to high-purity industrial water, proving the long-term stable performance of Siemens' membranes. Siemens' leadership in engineering, research and development, together with the ISO 9000 certification, and the greatest experience in the global membrane market and Petroleum based market, ensures the minimum risk across all facets of project execution.

In addition to installed capacity, it is worth noting that Siemens' hollow-fiber membrane manufacturing facility is the world's largest. Located in Windsor, Australia the facility is capable of producing 22.7 million square feet of membrane area per year .

Siemens is a world-leader in control and instrumentation engineering with unmatched experience in the execution of successful projects. With a considerable amount of instruments and control in these MBR plants, Saudi Aramco can be assured of continued reliable performance with Siemens.

1. SYSTEM PROCESS DESCRIPTION

1.1 PACT - MBR PROCESS DESCRIPTION

An average of 4900 m3 per day of waste water will enter the Petro ™ PACT -MBR plant.

The influent will come from two different sources:

1) the sanitary wastewater sewer (sanitary wastewater - average flow: 57 m3/d - 15000 gpd)

2) the Jeddah Refinery (industrial wastewater - average flow: 4843 m3/d)

The industrial wastewater will be treated in a Walnut Shell Filter in order to remove its oil content and will be sent to the equalization tank.

The sanitary wastewater will be coarse screened and de-gritted by means of a mesh (3 mm spacing) coupled with a grit removal chamber. A screw conveyor placed in the feed pipe will carry the separated solids and discharge them into a hopper.

The de-gritted effluent will be screened again by means of an enclosed perforated plate drum screen and sent to the equalizations tank. The screens (1 duty + 1 stand by) will employ 1.5mm perforated plate to remove fibrous material from the water. The screen utilizes high pressure water to backwash the drum. Screened solids removed from the process flow out of the system by gravity into a covered collection bin.

The two streams (sanitary and industrial wastewater) will be equalized in two above grade mixed equalization tanks. MBR feed pumps will then transfer the water (through a flow meter and a temperature probe) to a splitter box and from there to the two 75% treatment trains . PAC will be added to the splitter box.

Each biological treatment system will be made up of one aerated treatment stage dedicated to the oxidation of BOD and ammonia to CO2 and N03-. Denitrification is not required at this time. In the aeration pH will be adjusted by means of a caustic and an acid dosing system.

Aeration tanks 1 and 2 will be equipped with air headers and coarse bubble diffusers to provide dissolved oxygen to the biomass liquor. Dissolved oxygen will be monitored in each aeration tank, the level of which controls the air supply from the blowers. Intake air for blowers will be drawn from the ambient air and filtered by a baghouse filter and an inlet guard filter mounted on each blower.

The mixed liquor will flow by gravity from the Aeration Tanks 1, 2 to the MOS Tanks 1, 2 respectively, which house the membrane filters. Each MOS tank will be equipped with a piping distribution system with Jumbo Jet® diffusers to evenly distribute mixed liquor to each of the membrane modules. Air flow to the MOS tanks-from AerationlMOS Blowers will be controlled by a flow meter, and will enter each membrane rack in the MOS Tanks 1, 2. Internal Membrane Rack piping will distribute air to the bottom of each membrane bundle to provide a two-phased flow of air and sludge across each membrane bundle to continually scour and provide fresh water to the membrane surfaces. The even cross-sectional up-flow of thickening mixed liquor overflows the

)


MOS tanks 1, 2 and flows by gravity to a suction header from where 2 MOS recirculation pumps will pump it to the splitter box located at the front end of Aeration Tanks 1, 2 to maintain the system mixed liquor solids at the required concentration.

The MOS tank and the Aeration tank will be provided with spray nozzles to avoid foaming issues on the liquid surface.

Mixed liquor solids will be wasted from the system via the discharge of the MOS Recirculation Pumps on a timer-controlled schedule. A flow meter on the wasting line will totalize the waste flow to a pre-controlled set point whereby the wasting valve will be closed. The sludge will be diverted to a sludge sump and from there it will be pumped (by means of sludge transfer pumps) to the drying beds.

The filtered water will be drawn through the membranes by means of Filtrate Pumps. Level transmitters in Aeration tanks 1, 2 control VFDs on the respective Filtrate Pumps, allowing Aeration tank level to fluctuate based on current MOS tank functionality and membrane TMP.

Periodically, based on a timer, the flow from the filtrate pumps will be stopped to allow the membranes to relax. This process allows the fibers to regain their original size and shape. During this period, the MOS Feed flow and MOS scouring air remain on to the MOS tank to continually scrub the membranes. The relaxation and continuing air and sludge feed past the membranes keeps the membrane permeability high.

Maintenance clean will be also carried out on a weekly basis. During MC the flow through the membranes will be reversed (backwash) and a chlorinated solution will be pumped by the filtrate pumps to the membranes' lumens.

After a sustained period of operation, relaxation and MC alone are not enough to maintain membrane permeability. Based on transmembrane pressure and flow, an alarm signal will alert the operator that a Clean-In-Place (CIP) cycle is required to thoroughly clean the membranes . When convenient for the operator, the CIP procedure will initiate, which proceeds automatically. The CIP begins by stopping the associated feed flow to the MOS tank under cleaning, opening the MOS Tank drain valve and allowing the tank to drain to the system drain. After the MOS Tank is empty, the system will utilize plant water to effect a rinse o(the tank and membrane modules. The next step involves a fill of the MOS Tank for rinsing through the MOS feed piping This fill is accomplished via the Filtrate Pump. The MOS Tank is again drained to the system drain. After the MOS Tank is empty, the system will conduct one final spray rinse of the tank and membranes. After completion the MOS tank is once again filled with filtrate from the on-line Filtrate Pump. At this time, hypochlorite is introduced to the MOS Tank via Hypochlorite Transfer Pumps located in the control building. The Sodium hypochlorite transfer pumps will add hypochlorite for a preset period of time during the fill to make up a solution with a preset free chlorine concentration. The Filtrate Pumps corresponding to the train undergoing CIP turns on after the MOS Tank has been filled. The Filtrate Pump will take suction from the MOS Tank and recirculate the hypochlorite solution around the MOS Tank and across the membranes. The recirculation continues for a preset period of time after which the PLC signals the end of the CIP procedure.

After the CIP procedure is complete, the tank is drained to the system equalization tank via the system drain. After the tank is drained, the system will initiate a re-fill of the MOS Tank with the corresponding mixed liquor from the corresponding aeration tank. Once the MOS Tank is full, the Filtrate Pump will resume and the system is back on line.

Subject: Re: Cost, Size, Description of Sludge Beds for 600,000 gpd MBR Plant

John,

At Udhailiyah STP (0.85 mgd plant), there are two sludge drying beds, each 465 m2

I have attached an excerpt from the PP for Rahimah STP, where we are putting in new drying beds:

2.5.12 Sludge DQling Bedl

The existing sludge drying beds will be demolished to provide space for new equipment andfacilities. New sludge 'jlying beds will be provided near the south perimeter of the STP. A total of 54 dlying beds will be provided. Each

bed will provide 250 1// of drying area. The beds will be a concrete, at-grade structure, provided with a hard boltOI/, of concrete. A decant adjustable weir gate and drain box will allow for decant of the separated water to a plant sewer, which will drain to the influent pump station.
