Gujarat Wedge Wire Screens Ltd.

Halol, Panchmahal, Gujarat

The GUJARAT WEDGE WIRE SCREENS LIMITED intake screen removes rubbish, stones, leaves and aquatic life forms from the flow prior to entering the supply pipe (penstock). This is often a requirement of environmental protection agencies. A poor intake is normally the cause of most hydro turbine system problems. Poor intakes may allow small stones to enter the penstock that can cause serious damage to the Pelton rotor or cause the jets to suddenly block resulting in severe water hammer that can rupture pipe and fittings.
Our GWWSL intake screen is not limited to small hydro schemes; it can also be used for domestic, farm, village and small town water supplies.
Our GWWSL intake screens are designed to provide low maintenance screening solutions for water intakes without the need for any moving parts. The self-cleaning ability and high abstraction flow capacity is due to the shape of the screen and the arrangement of the wedge wires that make up the screen.
The GWWSL screen uses the Coanda effect, which is the phenomena in which a jet flow attaches itself to a solid surface and remains attached, even when the surface curves away from the initial jet direction. The screen is built from wedge-shaped wires that have suitably angled faces to which the flow attaches.
Water is directed over the screen in a fast moving sheet, and the bars deflect it into a tank below whilst debris continues straight on and is washed off by the surplus flow.
Water and some fine silt particles (<1.5mm) pass through the screen, whilst larger silt and debris is excluded and deposited downstream. During times of low river flow the screen capacity may be greater than the available water. Under these conditions debris can build up on the lower parts of the screen. This will be washed off the next time the river flow rises above the screen capacity.
You can order your intake so that the pipe can attach on the left hand side (LHS), right hand side (RHS) or in the central location as shown below. The central option is possible but not advised, unless there is no space for a LHS or RHS fitting.
If possible you should avoid a sharp elbow connection to the intake casing. Once the pipe is connected to the intake it can be concreted over to help protect from floods. It is very unlikely you will ever need to separate the intake tank from the pipe again.

Each complete intake comes with:

• Black roto-molded LDPE casing
• Coanda screen
• Outlet pipe fitting based on your selected size option
• Acceleration plate and securing tube
• Low entry-loss (bell-mouthed) internal fitting
• Vortex breaker plate (only on 1/2 screen version)
• Securing anchors so it can be concreted into position

Coanda Intake Screen, also called Coanda Hydro Screen, provide self-cleaning with the special geometry based on the Coanda Effect phenomenon. The Coanda screen is capable to enable liquid-solid separation with high filtration performance. The hydro screen prevents the sediment, sticks, rock, and dirt with the small-sized openings with no-moving parts and no power requirement.

How Does It Technically Work?The curved screen of the Coanda Screen consists of V-shaped wedge wires that are placed in exact locations that will create a Coanda effect for the filtration. These wedge wires have a specific gap and tilt angle relative to each other.
Water flows through this gap between the V-shaped wedge wires by preventing other particles. Thus, this gap and the tilt angle defines both capacity and filtration performance. Also, the curved shape of the Coanda screen helps the filtration process complete accurately by the exerted forces of flow. Unwanted particles such as sediment, rock and stick follow the curved shape with this exerted force. As a consequence, it provides self-cleaning.
In the design of the Coanda Screen, important parameters such as tilt angle, open gap, acceleration plate and curved screen must be taken into account. Because more gaps and high tilt angle cause poor filtration performance but high capacity. Thus, an undesirable situation occurs with ineffective filtration performance.
To avoid this poor filtration performance, important parameters such as gap, tilt angle and curve of the Coanda Screen must be calculated, designed and manufactured accurately for the best utilization of the Coanda Intake Screen. ADENCO is capable to provide accurate and customized design and manufacturing for your applications and requirements with our Coanda Screen Engineers.

Product DescriptionBacked with rich expertise and knowledge in this field, we are counted amongst the foremost manufacturers and exporters of finest quality Demister Pads. We design and manufacture these pads as per the industrial quality and standards using different types of quality materials. Demister Pads, we are offering in the market, find wide application in diverse industries of chemical, petrochemical, petroleum and refining industries.

Further DetailsDemister Pad is also known as mist eliminator, diesel injector filter, knitted wire mesh, mister screen, socks e.t.c. We manufacture demister pads as per customer specifications.

Application :GWWSL demister pads have used in gas-liquid separation e.g. moisture separators for compressed air and column packing pads. Demister pads are also used in the separation of water droplets from Steam. These pads have a wide range of applications in the chemical industry, petroleum industry, pharmaceutical industry, and separation equipment manufacturing.
Demister pads are effective in separating liquid phase from the vapor phase. Typically demisters are mesh-type coalescers but can be constructed of a vane pack as well. The function of Demister Pad is to coalesce fine droplets so that the combined drop is heavy and pulled down due to gravity. Usage of Demisters can help in the reduction of the size of Separator Vessels. The gas/vapor exiting the Separator Vessel is devoid of liquid droplets.

Working Principle :Demisters are employed for the separation of the Liquid Phase from the Gaseous Phase. Gas or Vapour carries liquids in small droplet form. When the Gas / Vapour passes through the demister pad, the fine liquid droplets collide with the filaments of the demister pad. Small droplets adhere to the filament. A sequence of droplets keep joining onto the filament and eventually combine to form bigger drops that are heavy enough to be pulled down due to gravity. The gas being lighter is usually routed to exit from the top of the Separator Vessel and the Liquid from the bottom. Thus, Demister Pads are very effective in Gas-Liquid Separation.

Structure:Single Piece or Multiple Pieces for installation through Man Hole. With Support Grid or Without Support Grid, depending on customer requirement.

Structures of Sieve Bend ScreenWedge wire sieve bends are made of stainless steel wedge wires. They are consist of a concave curved profile wire screen, which are inserted into a stainless steel frame. The wedge wire sieve bends are manufactured by wrapping and welding stainless steel V-shaped profile wire and support rods. Then the panel screens are cutting and curved into arc screen. The wedge wire sieve bends have continuous slots, which has efficient filtering performance. Forces exerted as materials flows against the curved surface, curved screen structure has better filtering and greater capacity than the wedge wire screen panel.

Working Principle of Sieve Bend ScreenDSM screen (sieve bend screen) is ideal for sizing and dewatering applications to remove solids from liquids or in solid/solid separation for dry feed situations. When the filtering materials flows against the sieve screens, Sieve bend screens can be manufactured into a variety of width, arc length and aperture to suit the flow rate and material sizing being separated. The feed materials are directed vertically and tangentially over the full width of the upper screen surface, then the material flows down the concave surface at right angles to the opening between wedge profiled wires. Wedge wire sieve bend screen has continuous slots, which supplies large open area and efficient filtering performance. Curved surface structure supplies higher flow rate, greater capacity and better filtering than wedge wire screen flat panels.
As a result, Thinner materials on the underside is deflected and passed out between the wires.

Features

• High filtering, sizing, dewatering performance.
• Good mechanical properties.
• Great capacity than the traditional vibrating screens.
• Corrosion and rust resistance.
• High temperature resistance.
• Low maintenance. It is easy to clean and need less maintenance.

• Long and durable service life.
• Easy to install and replace.

ApplicationsThe wedge wire sieve bends are mainly used for dewatering, sizing and waste water cleanup applications. They can be used in various fields, such as:

• Sewage treatment.
• Laundry wash water cleanup.
• Poultry, fish, fruit and vegetable waste water processing.
• Minerals processing.
• Paper production.
• Textile plants.

Working Principle of Wedge Wire Screen Tubes in Radical ReactorsCatalytic reforming is an important process for improving gasoline quality and producing petrochemical raw materials. Catalytic reformer is one of the most common devices in modern petroleum refineries and petrochemical catalytic reforming joint enterprises. According to the flow direction of oil and gas in the reactor, it is divided into axial reactors and radial reactors. Radial reactors are widely used in modern reforming units.
The existing radial reactor is equipped with a gas distribution device and a gas collection device, which are respectively installed in the center and around the reactor. The gap between the two is filled with catalyst to form a catalyst bed. There are two kinds of wedge wire screen tubes in radical reactors: scallop wedge wire screen tubes and cylindrical wedge wire screen tube. The devices installed around the reactor are scallop wedge wire screen tubes (flat tubes). According to the flow direction of the gas, they respectively serve as the flow diversion channel or the flow collection channel of gas respectively. The device installed in the center of the reactor is a cylindrical wedge wire screen tube and the bottom of the wedge wire screen tube is connected to the outlet of radial reactor. When the reactor is working, the raw materials enter from the inlet at the top of the reactor, and a series of reactions occur under the action of the catalyst. The gas will be collected in the cylindrical wedge wire screen tube and transferred to the next reaction stage.
Catalytic reforming is an important process in the refining and petrochemical industries. In the actual catalytic reforming reaction, many unexpected situations may occur. For example, in the case of sudden shutdown, the catalyst will move toward the scallop wedge wire screen tube where the gas is accumulated in the reactor. The scallop tube is subjected to a large external force, which may lead to instability and deformation. Therefore, we must choose high quality wedge wire screen tubes to ensure their compressive strength, flatness, verticality and other factors to improve the catalytic reforming effect.

Flat Panels are the most widely used type of Wedge Wire Screens mainly in the mineral processing both for stationery as well as vibratory decks. Flat panels manufactured by GUJARAT WEDGE WIRE SCREENS LIMITED are most dependable for effective sizing or classifying as they have accurate bar spacing from as low as 0. 01 mm to 4.5mm at interval of 0. 01 mm. Because of Looped construction they probably have the highest strength for any particular size and are self supporting and do not require support for long distances. The panels are either continuously or intermittently welded on the lower side of loop to provide complete rigidity to the panels thus becoming very effective in transmitting the vibrations without mechanical failures. The panels can be made with any type of fitment as per the requirement of the customers and for particular machines i.e. the side bar can be of Mild Steel or Stainless Steel square bar or of good quality, hook strips etc.

GUJARAT WEDGE WIRE SCREENS LIMITED has developed Rotary screens complete with side flanges and support/ drive drums of Stainless Steel/ Mild Steel mainly for Sugar and other Chemical plants to achieve very efficient filtration. Our rotary screens have very .high strength coupled with very high open area and rigid construction.
Rotary Wedge Wire Screens remove solids and other debris from wastewater flows to protect downstream equipment such as pumps and irrigation nozzles. The screens are suitable for all types of wastewater. The solid screenings are discharged by gravity. Screens are operating at Chemicals plant, Papers & Pulps, dairy farms and at food processors. They are designed to reduce blockages, maintenance and power consumption.
Rotary Wedge Wire Screen operation: The wastewater enters a weir and is evenly distributed onto the sidewalls of the drum. The solids are retained on the screen surface and the liquid flows through the screen openings. The solids are transported by flights to the open end of the drum. The rotation of the drum allows the entire screening surface to be continuously washed by the wastewater. Cleaning is also done by intermittent use of external spray nozzles.

Rotary Wedge Wire Screens feature: - In-feed flow distribution weir - Screen element of 304 stainless steel construction with screen size to suit flow and chosen screen aperture.

GUJARAT WEDGE WIRE SCREENS has developed run down screens (D.S.M. type) complete with box and curved wedge wire screens to suit particular requirements of the customer in Sugar, Paper and Pulp, Water treatment and Chemical industry
A no-moving part unit that cascades solid laden slurry downs a wedge wire screen to separate solids from liquids. The slurry is pumped or gravity fed into the unit’s top chamber, flows over a full width weir and cascades down the curved screens surface. The liquid passes through the screens voids into a collection chamber below. Solid particles larger than the screens void size stay on the surface, and as this accumulating mass increases in weight/volume, gently slides down the screens surface, compacted and further dewatered as it travels down. At the bottom discharge chute, the solids simply drop off or in some applications, go for further dewatering by a drum or screw press unit. The static screen version has it screen rigidly fixed in position whereas the other, more efficient unit, has its screen mounted to enable a small motor to vibrate it.

In addition to flat panels, wedge wires can be readily made up into full cylinders and segments of cylinders. In most cases, the cross rods lie along the circumference and the profile wires lie parallel to the axis. Occasionally, this arrangement is reversed.

Filter Solutions offers a complete range of resin trap styles to suit virtually any application. Our resin traps provide a high percentage of open areaminimizing pressure loss through the system. Resin trapscan be designed to suit either new or existing strainer bodies and piping.
Resin Trap Filters are essential protection devices for water treatment systems. These trap filters are manufactured from Stainless steel material & contemporary techniques in adherence with the international standards. Offered trap filters are checked by vendors quality experts on several quality parameters before supplying in the market.

Features:

• Perfect design
• Anti corrosive
• Robustness

Other Details:

• The trap is a Filter Basket type with fine filtration up to 0.2 mm (200 microns) with more filtration area.
• The strainer can be installed in backwash line before the drain manhole
• We make traps are designed in corrosion resistant alloy steel material to take care of PH values of flushed water containing slipped resin granuals.

A resin trap is used on service outlet and backwash lines on:

• Cation, anion, mixed bed, and selective ion exchange resin systems
• Commercial and industrial water softeners
• Activated carbon filters
• Greensand, multimedia, sand, anthracite, etc. media filters
• The resin trap holds back escaping media at the onset of a failure
• Visual monitoring will alert the operator to under drain, lateral or strainer damage prior to catastrophic failure and extensive loss of media
• An unmonitored resin/media trap will collect the ion exchange or media in the resin trap until the water flow is completely blocked, but it will still protect the downstream product, process, equipment and/or pumps from damage and contamination

Resin Trap Benefits:

• Saves your downstream product, process, equipment and/or pumps from damage ancontamination.
• Eliminates mass resin/media loss into piping distribution system Prevents loss of resin during backwashing Visual detection of minor resin/media losses prior to catastrophic failure of major equipment.
