PROJECT MANAGEMENT, ENGINEERING CONSULTANCY, AND SUPERVISION
SERVICES FOR THE DESIGN, BUILD & TWO YEARS OPERATION OF THE SECOND CENTRAL EFFLUENT TREATMENT & RECYCLING PLANT (CETRP II) FOR
PTA/PET/PIA EFFLUENT AT SOHAR INDUSTRIAL PORT AREA
2 General Description of Work
Majis Industrial Services is the water services provider at Sohar Industrial Port Area (SIPA). It currently provides a whole range of water services to the tenants of SIPA including supply of cooling, potable and process water, and collection and treatment of wastewater. Following Government’s directive to eliminate treated effluent discharges to the marine environment, Majis has installed a Treated Industrial Effluent (TIE) network to monitor and collect discharges from the existing tenants with the aim to further treat and recycle/re-use this TIE within SIPA. A Central Effluent Treatment and Recycling Plant (CETRP I) is being implemented at Plot 22. Oman International Petrochemical Industries (OMPET) along with OMPIA intends to establish, PTA-PET1 & PIA2 1plants at Plot 7 and 8 at SIPA. These plants are intended to be functional by Q2 2017. Majis is hence launching it Second Central Effluent Treatment and Recycling Plant (CETRP II) to be located at Plot 7. The scope of work for this tender includes project management, engineering consultancy services, and supervision of construction and commissioning of a Central Aerobic Treatment Plant (CATP) for the pre-treated effluent from PTA/PET & PIA facilities along with a Re-use & Recycling Plant (RRP) – together the CATP and RRP form CETRP II. The contract for the design, supply, installing, testing, commissioning, and operation (for two years) of the CETRP II facility will be implemented on a Design and Build basis by a specialist contractor. The plant shall be designed to receive treated anaerobic effluent of specified quality and to produce 5,000m3 per day of industrial quality water of 25ppm TDS or better.

3 Conceptual Design
CETRP II is part of the overall scheme to supply 28MLD of Industrial Water for cooling and process purposes to OMPET and OMPIA. 28MLD will be supplied by desalting seawater in the Second Reverse Osmosis Plant (RO II) [yet to be tendered], and potentially a standby 8MLD will come from CETRP II (additional provision is made to convert two potable water trains to process water by 2016).
OMPET is developing the PTA-PET1 plant whereas OMPIA will establish the PIA2 facility.
Both PTA-PET as well as PIA plants will have their own proprietary anaerobic treatment plants. The flows from the anaerobic plants will be discharged to the CETRP II which shall be designed on the basis of a biological aerobic process (CATP) followed by a membrane based recycling/re-use plant (RRP).
Diagram 1 below shows the overall scheme to meet the cooling water demand.
