ABSTRACT:
A screen assembly is described which comprises a flow channel along which sewage is intended to flow, in use, a continuous flexible belt entrained around roller or wheel means and projecting into the channel, and means for driving the belt. The belt is perforated such that relatively large solids carried along the flow channel in the sewage are trapped by the belt adhering thereto due to a pressure differential across the belt. Movement of the belt lifts such solids from the flow channel. The belt is of thickness less than or equal to 1 mm.
