Inlet and industrial screens
Inlet and industrial screens
Inlet screens are designed to protect downstream processes and optimise their plant treatment capability.
WPL’s range covers a variety of process applications, including small and medium wastewater treatment plants used at industrial and municipal sites. It includes fine and course screenings, de-watering, compaction and screen handling equipment. All screens can be mounted in a concrete channel or can fit into a steel tank for above-ground applications. A choice of mesh sizes is available. The complete range of WPL screens can handle flows from 3-200 l/s.
Why use a screen?
Inlet screens prevent damage to downstream processes and improve their efficiency. They reduce contamination to watercourses and eliminate material that inhibits recycling.
What to consider when selecting a screen
- Flow – average and variation
- Type of effluent – storm, industrial, municipal
- Sewer type – long sewers result in heavy flushes of rags
- Degree of screenings removal required – screen aperture
- Type of cleaning required – manual, automatic
- Availability of power and wash water
- Health and safety – screenings contain pathogens and attract insects
- Handling, transport and disposal requirements
WPL’s range of inlet screens
Inlet bug screen
The WPL above ground circular bar screen has been developed as a mobile/temporary unit for pre-treatment of municipal and industrial wastewater. It removes fine solid impurities larger than 3 or 6mm, depending on the chosen screen aperture. It also removes grit up to 50mm, sand larger than 3 or 6mm, grease, fibres, and textiles.
The unit is equipped with an integrated bypass, which mitigates the risk associated with power failure or other damage to the fine screen. It also has an easy-to-open laminated cover, fitted with a ‘dead man switch’ cut-out for safety.
Why choose WPL inlet bug screens?
- 304 Stainless steel and plastic components in tank
- Low installation costs – above ground construction
- Durable and suitable for transportation
- Can be skid mounted
- Fine mesh bypass storm overflow prevents overloading
- Compact - suits most site applications
- Can be controlled by Plc
Inlet screw screen
Screw screens are a good general purpose inlet screen, designed for small and medium sized wastewater treatment plants. The screen is supplied for below ground installation in a concrete channel, or in a stainless steel tank where concrete channel is not required.
Maintenance is simplified by a unique pivoting system that allows the unit to be raised out of the housing or channel for cleaning. The outlet pipe can be rotated through 300 degrees to suit the site configuration with regards to screen storage, and can be fitted with optional de-watering and compaction equipment.
Why choose WPL inlet screw screens?
- Concrete channel or stainless steel tank
- Adjustable screen rod dimensions
- Screens can be supplied for deep inverts
- Low wash water and power requirements
Drum screen
The rotary drum screen is designed for separation of screenings from industrial and municipal wastewater effluent, and particularly for water containing viscose and fibrous elements, the unit can be fitted with (optional) compacting and de-watering equipment.
Flow is delivered by pump or gravity to the inlet section where turbulence is reduced in quiescent conditions in the inlet tank. Flows enter the cylindrical drum (out to in) through a high quality wedge wire screen, periodically cleaned by a skimming plate. Screenings fall into a hopper, which can be fitted with a compacting screw conveyor.
Typical flow rates of 3-850 l/s, with mesh sizes varying between 0.25 and 2.5mm
Why choose WPL drum screens?
- Stainless steel construction, including sieve
- Variety of applications
- Suitable for viscose and fibrous screening
- Optional de-watering and compaction in the same unit
- Can be skid mounted for portable applications
