WPL Inlet Screw Screen

Screening for smaller utilities and municipal applications

 

A WPL Inlet Screw Screen is designed for removal of screenings within wastewater prior to being received by the main treatment process. Removal of such screenings minimises blockages of downstream treatment processes. The inlet screw screen works by a screw mechanism which rotates to lift the screenings out of the inlet channel and discharge them into a separate container via a chute. ‘Screened,’ water then flows forward for further downstream treatment.

WPL Inlet Screw Screens are 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 for above ground use.

Maintenance is simplified by a unique pivoting system that allows the unit to be raised out of the wastewater flow for cleaning. The ‘screenings,’ outlet pipe can be rotated through 300 degrees to suite the site configuration with regards to screen storage and can be fitted with optional de-watering and compaction equipment.
