The screen cylinder rotates on four wheels and it driven by TEFC motor, geardrive and corrosion resistant chain and sprocket. It has a fixed spray bar for an automatically applied cleaning shower.

Operation
The influent enters a headbox, extending 2/3 the length of the drum, where the flow is evenly distributed onto the sidewalls of the drum. Solids are retained on the screen surface as the liquid flows radially through the openings. Splash guards direct the liquid filtrate to a central drainage area, and the solids are transported axially, by flights, to the open end of the drum. The rotation of the drum allows the entire screening surface to be continuously or intermittently washed by a fixed external spray bar fitted with a bank of fan jet, spray nozzles.
