Method of 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 by fitted with a bank of the fan jet, spray nozzles.
