Abstract

A screening system for solid removal includes a housing and a screen positioned within the housing. A flow inlet is operatively connected to an interior chamber defined by the screen. A sump is downstream from the flow inlet for capturing solids that do not pass through the screen. A flow outlet is downstream from the screen in fluid communication with the flow inlet. A moveable cleaning assembly may be positioned either within a perimeter of the screen, around the perimeter of the screen or both. The moveable cleaning assembly is moveable with respect to the screen.

Abstract

A dewatering system (100) for removing solids from an influent includes a filtration assembly (106) and a feed pipe (104) upstream thereof. The dewatering system includes a solids receptacle (114) downstream of the filtration assembly (106), and an effluent collector (116) adjacent to the filtration assembly (106) and in fluid communication with the filtration assembly (106). The dewatering system (100) includes a sensor (118a-h) to sense a characteristic of an influent, an effluent and/or a solid. A control system (120) is operatively connected to the sensor (118a-h) to receive a sensor signal therefrom and to generate an adjustment signal based on the sensor signal to improve the efficiency of the dewatering system (100).
