Method of Operation
The influent enters a short spillway, which extends into the interior of the drum, where the flow is distributed onto the sidewalls of the drum, The 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 spray nozzles
other size of screening opening are availabe.
