- Model IFU Series - Rotary Screen



IFU Series of Internally fed Rotary Screens have cylindrical drums mounted horizontally on four shaft-mounted wheels. The drum rotates at 4 rpm and is driven by a TEFC motor, geardrive. stainless steel roller chain and sprocket. The IFU/W series screening element is slotted, wedgewire screen, with openings ranging from 0.010 to 0.100 inches, and the IFU/M series screen has a mesh lining, with openings from 100 to 500 microns. The IFU is a compact uni-frame screen that typically is applied to effluents containing moderate to low solid loadings.

The influent enters a headbox, which extends 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. Splashguards 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.
