Helicoidal Conveyor Screen TWISTER ®

CHARACTERISTICS:

The Helicoidal conveyor screen TWISTER ® is combined equipment for the separation of solids in the waste water and their posterior compacting and dehydration. The solid material in suspension in the transporting liquid deposits itself in the screen blocking it and causing a raise in the upwards water level and a drop of the downwards water level. At that moment the helix starts to work, cleans the screen, brings the material up, it dehydrates it and it compacts it.

The equipment is composed of:

- Filtering screen- Transporting conveyor- Compacter

The filtering screen is formed by a screen with mesh of 0.25 to 10 mm that retains the solids in suspension in the transporting liquid. This screen is kept clean by means of the corresponding brush which is fixed to the exterior extreme part of the helix.

The screen can be of two types:

- Johnson profile type screen between 0.25 and 10 mm- Perforated or triangular plate screen with holes between 3 and 10 mm

The transporting conveyor is formed by a helix without axis that allows the deposited solids to be raised. The non-axis conveyor allows extracting differently shaped and sized materials that in another way are difficult to transport.

The compacter, the own transporting helix serves to carry out the compacting – dehydrating of the screenings, with results of a volume reduction higher even than 50%.

Its advantages:

1) Totally automatic work, with possibility of rotation speed variation needs.

2) Screened solids exit hopper, length according to application

3) Screened solids compacting system, this system includes a compacting screen washing system, which avoids the screen to be clogged and eases the water exit.

4) The tilt system allows to examine at any moment the state of both the filtering screen as well as the Helicoidal screw

5) This screw zone is simply the transport of the screened solids, which are directed to the compacting head, the screw is hollow.

6) Filtering screen, with possibilities of execution in Johnson profile between 0.25 and 10 mm and in perforated or triangular plate screen with holes between 3 and 10 mm

7) Helicoidal spiral with special design which has a anti wearing brush incorporated, this is the one that carries out the screening of the solids.

(NOTE: As optional we can incorporate a filtering screen washing system)

Hydraulic Automatic Screen HIDRORAKE®

CHARACTERISTICS:

In order to try to solve the separation problems, an Automatic Screen System with the following advantages was developed:

- Without gears- Without chains- Without cushions- Without mechanical torque switches.- Without drivers- Without wheels no rods- Without fixed guides for the brush

In year 1983 the two first screens with these requirements were assembled in the Vilanova and Geltrú E.D.A.R. for our client Dragados Construcciones, S.A.

From that date on, we have been constructing them, and at the same time our technical department has been introducing improvements that have increased its performance and dependability and reduced its maintenance.

Basically, the operation idea of the HIDRORAKE ® screen, is to reproduce by means of a headstock and two oleo hydraulic cylinders, the movements that a person would do to clean a screen with a rake, which would be,

- Raise the rake, and being in upwards position, put it down to the bottom of the channel- Nail the rake in the screen and pull it upwards, raising the solids retained in the screen- Discharge the retained solids in a container, endless carrier, band, basket….

For the operation of the HIDRORAKE ® Screens, there is a control board placed in a board, which contains the hydraulic and electric group. In that board are located;

- A function selector, automatic, manual or stop.- Starting and stop buttons.- An hourly temporized clock.- A functioning control pilot.- A thermal trigger control pilot.- A general switch.- A pilot indicator of network.

If the screen is originally equipped with endless band, compacter, or garbage extraction conveyors, the board will include;

- A function selector, automatic, manual or stop.- A functioning control pilot.- A thermal discharge control pilot.

The board is protected by a transparent methacrylate casing that prevents it from getting wet in case of positioning through it.

When the screen is located in places without surveillance or fence, the command board is protected by a metallic cover with key that prevents it from being manipulated by strangers.

One advantage of the operation of the HIDRORAKE ® Screen is that it in no movement in the rake it has fixed guides, which means that if it cannot raise the quantity of retained solids or if a stuck object is retained, it stops rising, it raises above the object, advances and comes down again continuing its way up to the discharge point.

To eliminate the maintenance problems, we have placed the following;

- The scraping arm in stainless steel, AISI-304 or 316 qualities.- Nylon exterior supports (without greasing).- Filtrating screen, in stainless steel of AISI-304 or 316 qualities.

- Body and frame, in carbon or hot dip galvanized steel.- Hydraulic elements, submerged in oil.- There does not exist any submerged mechanic element.

The needed maintenance consists in watching the oil level in the deposit.

Due to the special operation characteristics of the Screen HIDRORAKE ®, a screen of triangular profile has been developed, with which an effective passing of up to 1.00 mm is obtained. This screen and the rake that operates above it are stainless steel and do not have jags.

OPERATION:

Manual Position: We will position the selector in manual position, and the we will press the start button, the rake will descend elevated up to the bottom of the channel, at the end of the its trip it approaches the screen and will ascend dragging the objects it finds retained, up to its resting position. A scrapper cleans the rake when it reaches the upper position.

At any point, when the stop button is pressed, the rake stops, maintaining its position. To start its movement, the start button will be pressed.

Automatic position: We will place the selector in automatic position, the operation of the screen will be conditioned by the timer, which we can determine as many times we want the screen to operate in an hour and during how many time.

The cycles described in the manual operation are repeated in the automatic one.

If the screen is equipped with an endless compactor or with a transporting band, by placing its selector in automatic position, it will function at unison with the screen. In order to prevent the mentioned equipment to remain full of garbage, when the screen performs the last sweep and stops, the endless compactor or the band, will continue operating some seconds, enough to dispose of the solids.

SECURITY EQUIPMENT: The movement of the rake, downwards, upwards, as well as the one of approximation to the screen, is protected by effort limiters that act directly over the oil flow that feeds the hydraulic cylinders.

These limiters are easily adjustable and because they are in the inside of the bench and in oil bath their characteristics are not affected by the pass of time.

The discharge of any of them produces the stop of the movement it controls, without being near to impair the screen or any of its components.

Four limiters exist, which protect with different pressures the four movements of the two cylinders.



This allows us to adjust the effort of each movement independently from the rest.

The screen is electrically protected by thermal magnets with differential and general power switch.

For the manoeuvre circuits, the tension has been of 24 v, both inside and outside, complying with the manual regulations.

OPTIONAL EQUIPMENTS:

To start the screen, it can be equipped with:

A maximum buoy, upstream if the level goes up excessively indicating the screen is dirty, the screen will start operation until the level descends, this will happen provided that the screen selector is in automatic position.

In the normalized electrical board, the circuit of this buoy has an exit lead, but the buoy does not

A buoy upstream and downstream, the buoy down will give us the start order when it descends up to a minimum level, provided that the buoy upstream detects it exists a superior level.

A system to detect charge loss, this system allows predetermining a maximum charge loss, in function of which the screen will start operating.

The employed system may be by means of two ultrasonic sensors or through two detectors and a differential pressure measure.

Distance control, the electrical board, exits can be foreseen to detect from distance the electrical failure of thermal trigger of the engines, we can also adapt a device that indicates a general failure of any element that produces that the screen cleaner cannot finish a cleaning cycle.

The HIDRORAKE ® screen, is built by the following elements:

- Fixed Frame- Movable head- Control bench- Filtrating screen

FIXED FRAME:

Built in welded steel plate, it constitutes the support of all the assembly, formed by a fixed bench that is coupled to a metallic profile structure that has the mission of fixing the screen to the floor by jeans of metallic nails or anchoring plugs.

The command bench is fixed to the inferior structure forming a homogeneous assembly.

Movable head: It is built in stabilized welded steel plate before its mechanization; this bolster supports the scrapping arm with the picking rake.

The scrapping arm is fabricated in stainless steel tube and it slips by means of synthetic material cushions, anti-wearing and that does not require greasing.

The traveling of the rake is made by means of a hydraulic cylinder.

The moving bolster is fixed to the static frame by means of an axis that allows oscillating movement, with which we manage to make the rake descend in an elevated position and gets up in position that presses the screen. We achieve this movement by means of another hydraulic cylinder, the cylinders are constructed with normalized materials and in the parts in contact with the water we put a hard chromium finish, to avoid corrosions and wearing.

The rake is built in carbon or welded steel, the jags are built in an independent piece, which simplifies its replacement in case of wearing down.

When the screen is of stainless steel triangular profile, the pointed scrapper is substituted by aluminium lineal or other suitable material.

All the bolters have a built- in residual ejector, that cleans the rake once it reaches its highest position.

Control bench: It is constituted by a metallic cabinet, and the hydraulic group with the oil deposit is located inside.

At the front of the bench and protected by a methacrylate board, the controls of the screen are located.

The hydraulic group is formed by two independent oil circuits, produced by two gearing bombs and commanded by regulating and pressure limiting electro valve.

All equipment is manufactured by EEC norms so its elements can easily be found in the market.

Endorsed to the bench or in its inside the electrical board is located, which automatizes the screen operation, being protected by a differential, thermals and fuses.

Screen: Our normalized screens are constituted in triangular profile and always in stainless steel material of AISI-304 or AISI-316 quality, for meshes from 1.00 mm up to 10 mm.

For meshes of 10 mm or more, they are built of rectangular profile and in AISI-304 or AISI-316 stainless steel materials.

The rake will have the same finishing and material of as the filtrating screen.

Because the filtering screen does not form a sole part of the Screen, this allows its replacement without having to disassemble the whole. This entails the possibility to change mesh, the material or the finishing very easily.

Finishing: The normalized finishing of the elements that are part of the screen and they are:

- The body and frame are of carbon or hot galvanized steel.

- The scraping arm is stainless steel of AISI-304 or AISI-316 quality.- The filtrating screen is stainless steel of AISI-304 or AISI-316 quality.

- Two layers of anti-rust priming and two layers of Epoxy resin blue Ral finishing.

Other materials can be used in function of the application of the screen.

Hydraulic Filter Press MURANO ®

CHARACTERISTICS:

Press filters are used more frequently each time, despite the discontinuous character of their operation and their high investment cost. Their development is explained by the following reasons,

1) Increasingly mechanization of the appliances up to the point to need a minimum of manpower or supervision for the cakes discharge operations or for the washing of fabrics. (In situ automatic washing).

2) Necessity to obtain cakes of great dryness, to allow:

- The auto combustion of sludge in their incineration.- The reduction if the fuel consumption in the case of thermal dry.- A more comfortable discharge.- The use of sludge as haulage material.- A limitation in the transportation costs of the dehydrated sludge.

The press filter is the only equipment which guarantees very high effective pressures (16 bars and above), with which maximum dryness of cake is achieved. (Generally above 30 %).

DESCRIPTION:

Press filters usually used to dry sludge are of the easy mechanization plaques type for the discharge of the cake.

A filter is usually constituted by a battery of vertical plates strongly supported between them.

Over the two faces of these plaques, filtrating fabrics are applied. Sludge arrive a pressure to the cameras created between two adjacent plaques.

The filtered recovered by the channels, in the back part of the fabrics, is evacuated by means of conduits arranged through the plaques.

Such plaques also consist of orifices whose alignment constitutes the sludge feeding ducts. These orifices are arranged at the centre or at the periphery of the plaques. With the central feeding a better distribution across all the plaque is achieved, of caudal, of pressure and hence, of drainage.

The fabrics generally are tissues of synthetic fibres. The careful selection of the quality of the fabric has great influence in the yield of filtration a pressure installation.

The space that exists between two plaques, in its central hollow part, corresponds to the thickness of the cake. The thickness can oscillate between 30 and 20 mm, depending on the specific resistance, more or less elevated from the sludge and the fixed duration of the cycle.

FILTRATION CYCLE:

Filling - during this phase of relatively short duration (3

to 10 % of total cycle), the filtration cameras, limited by the outside faces of the fabrics of two adjacent plaques, are filled with sludge to filter. The filling time depends on the caudal of the feeding bomb.

Filtration - once the cameras are filled, the continuous introduction of the suspension raises the pressure inside the cameras due to the closure of the sludge's pores, which concentrates.

Discharge - this operation consists in opening the filter. The plaques are separated one from another and the cakes formed between two plaques are successively expelled

Among the possible models and manufacturing combinations, we find an assembly of equipment of different dimensions and specifications, which we focus next,

Fp = press filter.H = hydraulic powering / M = manual powering.Tl = lateral transfer / Ts = superior transfer.R = Retruc (discharge with vibration).Lt = cake wash.Sp = Blown.

Also, the standard manufactured sizes are:

- 250 x 250 mm- 300 x 300 mm- 470 x 470 mm- 630 x 630 mm- 800 x 800 mm- 1.000 x 1.000 mm- 1.200 x 1.200 mm- 1.500 x 1.500 mm

Hydraulic Pincer AQUILLES ®

CHARACTERISTICS:

CONSTRUCTION

All the models have the same basic construction and can be supplied with the same special characteristics, such as:

> Wider or narrower grid> Greater working depth> Two speed motor for movement and elevation> Manufactured in stainless steel

The hoist is built in two profiles UPN and covered with a layer of steel. This way a profile is obtained whereby the cart is suspended with the grid. The advantage of having a loose grid is that it can clean screens of any width or height. The variable length of the hoist permits the positioning of the deposit anywhere. The following measures have been taken in order to fulfil the current levels of required noise:

> Nylon guide strips on the grid> Low noise elevation motor> Low noise hydraulic pump

In situations where additional requirements are to be fulfilled, the cart can be introduced in a completely soundproofed compartment.

CLEANING GRIDS Hydraulic pincer AQUILLES ®

Estruagua has supplied more than 300 units and installed more than 500 worldwide. We can modestly say that ESTRUAGUA has considerable knowledge and experience in the supply and installation of HYDRAULIC PINCERS. These cleaning grids can be found in many places with unwanted flotation or with suspended matter.

CONTROLS

A grid is placed in the channel. A chain block is placed on the grid, supported by columns. A construction made up of a cart and a loose grid, moves along the chain block. the grid is manufactured in a way that the grids bars fall between the screens bars when it descends, in order to extract any matter blocked. When it reaches the bottom of the screen, the grid closes hydraulically and then goes up to the highest part with the matter. The grid moves along the chain block to the tipping area.

CONTROLS

The cleaner can work in a completely automatic manner, controlled by the water level difference by means of electronic sensors. It is also possible manual drive or with a timer.

ADVANTAGES:

> The grid will be completely clean from top to bottom.

> The chain block can have bends, enabling it to reach any area of the tip

> There is the possibility of emptying directly onto in the chain block, container or tip.

> The open construction and lack of intermediate transport reduces the space required and dirty areas.

> Large obstacles are eliminated, such as mattresses, tree trunks and roots.

> Permanent absence of submerged parts.

> Freeze proof

> Does not require transporting belts.

> One unit is enough to work with various filtering grids

> The PLC control permits completely automatic and versatile working.

APPLICATIONS

> Drainage stations> Waste water treatment plants> Desalination plants> Storm tanks> Industry


Hydraulic Spillway Screen EAGLE ®

CHARACTERISTICS:

Floating material retention in sewage structures.

The pollution of superficial water resources, by the combination of the sewerage system and in part also by storm water tanks, consists of solids which are present in the residual water. This includes a wide variety of dissolved and semi dissolved fibres and solid substances, with different structures and specific weights (plastic shreds, sanitary towels, diapers, preservatives, fecal matter, paper, etc.).

The growing restoration of the natural water resources to their natural state makes essential to avoid the flow of floating materials in the future.

The construction of submerged walls in the sewerage structural stops only a part of the floating solids, because the considerable speed of the flow tends to increase with the short space that there normally is between the submerged walls; this speed increase promotes the flow of solid material.

Continuous basin-tanks can only perform their duty in a limited grade, because of the great volume of water and the ever increasing proportion of light materials.

Retention basin and channels have the inconvenience that the combined un treated water is poured into the river's flow once they are full.

A combination of tank-screen or tank-spillway screen is the best way to solve this situation. In this concept, the retention of the highly contaminated flow is the main duty of the tanks. In the other side, the screen will eliminate light substances, floating and solid, that would contaminate the area.

ESTRUAGUA EAGLE ®-SPILLWAY SCREENS:

ESTRUAGUA is specialized in the fabrication and development of spillway screens for sewerage structures.

For many years, we have been collaborating with professional experts of the sector of the water resources, and therefore, have gained much experience and references, both at national as international levels.

Estruagua EAGLE ®-Spillway screens have the following characteristics:

- Great performance reliability- Automatic mechanical cleaning

- Length wise cleaning of the screen, in ht e sense of the flow- Long lasting cleaning elements- Low maintenance requirements- Corrosion resistant design- Compact design of great resistance- Strong construction- Maximum spillway height 2.000 mm.- Maximum spillway length 10.000 mm.- Narrow spaces between bars (4 mm.)- Different working positions horizontal and vertical- Controlled handling of the spillway screen material- Function automatic / temporized / level- Minimum screen pass between 3.00 mm.- The material of the spillway screen is transported to a pre-defined location during the event of a storm.

That is why:

- It prevents any increase of solids in the incoming zone- It insures that the spillway screen stays clean even after the event and does not need manual cleaning

MAIN CHARACTERISTICS:

DESIGN CHARACTERISTICS

ESTRUAGUA EAGLE ® –Spillway screens- are designed in a modular system. They consist in a variety of elements that can be put together to obtain the best type of spillway screen for each particular application. The strong structure sustains the screen's screen, the cleaning lane with the pile of brushes and the hydraulic or pneumatic cylinder.

The screen of the spillway screen is built to pre-tension narrow bars of the screen. The crossing section of the small bar insures the optimum use of the screen area, low resistance of the screen and high flow capacity.

The standard interval of the bar is 4 mm, this way all the



undesirable floating materials are retained.

One or more clearing lanes are arranged in the sewerage depending on the length of the screen. These travel in guides by the screen surface.

The brushes, which are set on the cleaning lane fit in the screen's screen, supporting and guiding the bars of the screen's screen. The set of brushes therefore replaces the rigid transversal elements that are not desirable en a water cleaning system.

The cleaning of the screen is normally activated by level.

The mechanism is normally hydraulic.

POSSIBLE APPLICATIONS:

> Spillway in WWTP entries> Spillway in store water tanks> Spillway in pumping station> Spillway in water levelling tanks> Spillway in paper mills> Spillway in chemical industries> Spillway in dairy farms> Spillway in bottling plants> Spillway in leather factories> Spillway in canned products factoriesEtc.

CONSTRUCTION MATERIALS:

> Frame (SS. Aisi-340 or SS. Aisi-316)> Filtering screen (SS. Aisi 340 or SS. Aisi-316)> Filtering screens cleaning elements UHMWPS anti wearing> Level regulation elements (SS. Aisi-340 or SS. Aisi-316)

> In our spillway screens there are not:

> Pinions in contact with water> Chains that will break or rust> Circular cleaning brushes that will wear out> Submerged rolling> Engine driving gears pinion chain> Drilled filtering screens that will clog in short time> Mechanical torque switches

DIMENSIONS AND PERFORMANCE:

The ESTRUAGUA EAGLE ® –Spillway-screen- may be adapted to the structure in which it is installed and

also to the capacity of the required flow

- Length: Between 1,0. 10,0 m- Width or height: 0,4. 1,2 m- Capacity: 200. 5000 l/s- running charge: 400 V, 1,5. 3 KW

OPERATIONAL OBJECTIVE AND MAINTENANCE:

The ESTRUAGUA EAGLE ®. spillway-screen is typified by its strong structure.

When the material in the screen starts to get stuck, the failure is arranged repeating the operation. A change of special valve in the mechanism unit controls the movement of the cleaning lane.

Limiting switches are not necessary. The unit of the hydraulic mechanism may be installed out of the area of the screen.

Only two hydraulic lines get to the interior of the wetted chamber.

During the operation there is a continuous cleaning. It does not require support in the screen area.

The material of the spillway-screen is deviated and scratched in the last positions. The pre controlled transport of the screen material can be made to a pre-defined location.

An emergency spillway is supplied.

The ESTRUAGUA EAGLE ®. Spillway-screen requires very little maintenance.

After a storm, the screen is very clean so a manual cleaning is needless.

A monthly superfluous revision or checking after an exceptional rain is enough.

The entire design complies with the corrosion protection directive (CEE).

BENEFITS:

- It avoids the necessity of making a big water retention investment.- It avoids unnecessary contamination of the water receptor bodies- It is safe and reliable to operate.- It is strong (very resistant).- Low maintenance.- Little space between bars (4 mm).- Transport the material caught from the entry zone.- Materials 316L. o 304L.

Manual weir longitudinal spindle (Vm-002.d)Manual weir lowering board (Vrm-002.d)

Manual chisel Penstock(Co-003.d)Manual chisel Penstock flow meter (Coc-003.d)

As powering systems of the penstocks, the following procedures can be used,

1.- Manual.2.- Electric by engine drive.3.- Electric by servomotor.4.- Hydraulic.

Manual powering - such powering is performed by means of a bronze screw nut jointly with a trapezoidal thread spindle, and a manoeuvre steering wheel whose technical characteristics are described in the penstocks' design. Bronze or nylon rods, balls and sockets are also included. This powering in the penstocks of a single spindle can be direct or by means of a reducer, ball or rod axial rollers.

Engine drive powering - The engine drive to be introduced will be applied according to the dimensions and penstock's hydraulic pressure. It will have an optimum speed that produces a minimal wearing down of the spindle at the lifting of the penstock (0.03 mts/min.). The electrical powering will be accompanied

by an electronic torque switch to avoid over exertions, and two end of trip regarding end of road.

In penstocks of a spindle the engine drive will directly couple, in two spindle penstocks it will be positioned at the extreme or at the centre of the penstock and always accompanied of two gear boxes. It will carry a manual emergency steering wheel.

Servomotor powering - in the servomotor there will be: end of trip, torque switch, and regulation mechanisms of the penstock, which will allow to regulate the levels. The servomotor's position will be according to the number of spindles as well as the engine drive.

Hydraulic powering - by means of a hydraulic cylinder, it only is of application in penstocks of a single spindle. The stem is directly joined to the chisel and the cylinder anchors to the penstock's bridge. The system will be of all or nothing opening.

Hydraulic pressure calculus for channel penstocks:

L = Free opening of the wall in meters. (channel width)H = maximum water charge in meters. (water level channel)Ph. = Hydraulic pressure over the board in kg.

For channel penstock with board in reinforced plate and displacement rods,

Ph. = 500 x (L + 0.08) x H2

For the rest of the channel penstocks and chisels,

Ph. = 500 x L x H2

Hydraulic pressure calculus for bottom penstocks:


Penstocks and Weirs OPTIMUS ®

L = Free opening of the wall in meters. (hollow width)H = Maximum water charge in meters. (water level previous penstock)Ph. = Hydraulic pressure over the board in Kg.H´ = Maximum water charge over the penstock's centre. (Water level- penstock ´s centre difference)H = Free opening of the wall free height in meters.

For a sliding penstock,

Ph. = 1000 H´ x (L+0.05) x (h+0.03)

For penstocks with displacement rods,

Ph. = 1000 H´ x (L+0.1) x (h+0.05)

For penstocks of small bottom leaks,

Ph. = 1000 H´ x (L+0.025) x (h+0.025)

Pre-Treatment Compact Plant COMBIPRO®

CHARACTERISTICS:

In such pre-treatment it is included:

- The elimination of solids (screening or separation)- The grit elimination (grit removal)- The elimination of grease (grease removal)

The Pre-treatment compact plant COMBIPRO ® installations allow to carry out the above mentioned treatments in a single equipment and for flows up to 150 l/s (540 m3/h).

The waste water is introduced to the entry of the equipment through a flange connected pipe.

The solids contained in the liquid are trapped in the screen and during their extraction a series of nozzles of great performance and power proceed to their washing to eliminate the most of the existing organics substances.

In the lower level of the screen the compacting/ dehydration of the screenings is carried out with the obvious and significant reduction of their volume before they are discharged in a container or plastic bag designed for such purpose. The liquid that travels through the screen enters a hopper where, optimized by the introduction of air, the existing grit sediments. A conveyor takes care of its dehydration and discharges it into the container designed for this purpose.

In this same hopper, also optimized by the introduction of air, the process of the existing grease substances “flotation” is then carried out, and an appropriate device takes care of dehydrating them and discharges them in a container.
