OFS
OFS series of internally-fed rotary screens is the most versatile unit, applied on high flows with heavy solids loading for industrial wastewaters. The OFS features a modular design, with components bolted to a heavy duty based structure. The screen cylinder can be wedgewire, perforated plate or fine mess. The cylinder rotates horizontally on four trunnion wheels and is driven by a TEFC gear motor and corrosion resistant chain and sprocket arrangement

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 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.
other size of screening opening are availabe.
