DESCRIPTION:

IFS Series of Internally-fed Rotary Screens have cylindrical drums mounted horizontally on four shaft mounted trunnion wheels that are supported on pillow block bearings. The IFS/W series screening element is slotted wedgewire screen with openings ranging from 0.010 to 0.100 inches and the IFS/M series screen has a mesh lining with openings from 100 to 500 microns. The IFS is a base frame mounted screen that is versatile and can handle high flows and/or high solids. METHOD OF OPERATION 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. 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.
