Apparatus for dewatering sludge comprising a moving foraminous conveyor belt (10) driven in a single direction with a horizontal conveying run (11). Sludge to be dewatered is fed onto the belt at an input end of the conveying run so that liquid may drain from the sludge through the belt. Part way along the belt is disposed at least on ramp (21) having its lower edge in contact with or just above the belt surface to cause sludge to rise up the ramp thus enhancing the dewatering process. A plurality of spaced fingers (26) extend forwardly from the top of the ramp (21) thus leaving strips of the belt (20) free of sludge forwardly of the ramp and fingers.
