The Flo-Drum MBR Pretreatment Screen from Enviro-Care Company provides a triple face seal that creates a labyrinth that inhibits bypassing of fine solids, including hair. A cleaning brush on the exterior keeps solids contained within the screen basket. Exterior spray nozzles clean the screen and provide an additional containment barrier for fine solids. The screen basket is made of 304 stainless steel (316 stainless steel optional) perforated media with 1-, 2- and 3-mm openings available. Screenings are conveyed out of the interior solids capture trough to a washing cycle and then to dewatering and discharge. Screen diameters range from 600 to 3,000 mm. 815/636-8306; www.enviro-care.com.
