IFO - Internally Fed Screen - Overhung
IFO Series of Internally Fed Rotary Screens have cylindrical drums mounted horizontally on four shaft-mounted wheels. The drum rotates at 4-5 rpm and is driven by a top-mounted, TEFC motor, geardrive, stainless steel chain and sprocket. The IFO/P series screening element is a perforated drum with openings ranging from 1/16 to 3/8 inch diameter, and the IFO/W series screening element is a wedgewire drum with slot openings ranging from 0.010 to 0.100 inches. The screen is supported on a tubular frame and is typically applied to flume waters.
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.
