An apparatus (10) for the screening and removal of waste from waste water comprises a waste water channel (14) with a perforated screen (12) through which waste water flows. The screen (12) collects solid waste from the waste water which is then removed from the screen (12) using a mechanised (20). The head (20) is located at the end of a mechanical arm (18) which is pivotable and moved up and down a shaft (22) so that the arm (18) brings the head (20) into contact with the screen (12). The head (20) then moves up and down the screen (12) scraping away the collected waste and then the waste is removed by suction through an extraction tube (30) to a jet pump or suction pump and on to a compactor or treatment unit. <IMAGE> |
