Abstract

Sewage flows along a channel (2) in the direction from right to left and through an endless screening belt (4) located with its lower region in the sewage stream. The belt (4) consists of pivotally connected perforated screening elements (12) each consisting of a shorter part (14) and a longer part (16) connected at an acute angle to one another. The belt (4) travels anti-clockwise causing solid particles larger than the perforations to be carried upwardly on the shorter parts (14). When each screening element (12) reaches the upper region of the belt (4) the solids drop into a screw conveyor (30) which conveys them to a desired location. A rotary brush (24) and a liquid spray assist the removal of solids from the belt. Any solids which fall clear of the screw conveyor (30) fall back into the channel (2) upstream of the inlet region of the belt (4). This arrangement reduces the risk of solid sewage entering and polluting the cleansed liquid sewage effluent downstream of the conveyor belt (4). <IMAGE>
