The new, compact Rotary Drum Screen removes solids from industrial waste streams, and recovers solid product from process streams, at rates from 600 to 2,790 gal/min without blinding or clogging the screen. The product also reduces floor space and headroom requirements compared with non-rotating equipment of equivalent capacity. The stainless steel unit, Model 24-RDS-72, is comprised of a 24. in diameter x 72 in. long cylinder with durable wedge-wire screening, a variable speed drive, head box, discharge chute and support structure. Solids-laden effluent discharges from the head box and overflows a weir, flooding the entire length of the variable speed, rotating wedgewire drum screen. Solids deposited on the screen gravity-drain through slotted apertures to moisture levels in the 20 percent range before being removed by a doctor blade and chute. Liquid passing through the screen falls onto an internal baffle that concentrates the flow, forming a full-length water knife that impinges against the underside of the screen, dislodging any solids trapped in apertures, even when handling oily, greasy, fibrous or resinous matter.
Typical applications include: separation of various solids and sludges from municipal and industrial wastewater, food processors, pulp and paper production and rendering processes; removable of extruded pellets from cooling baths; and separation of debris from any variety of plant and equipment cleaning processes.
