Abstract: A sludge dewatering system comprising a moving foraminous belt (10) having a horizontal conveying run on which sludge is carried to permit drainage of water therefrom through the belt. In accordance with the invention a row of deflectors (12) are mounted on a pivotal cross beam (13) extending over the belt (10). Each deflector has a leading edge (19) and a pair of diverging and upwardly concave walls (21) whereby sludge proceeding along the conveying run of belt (10) is divided overturned and compressed by the deflectors.

Abstract: This invention relates to filter presses of the kind comprising a plurality of separate filter plates which are supported by or from a main frame so as to form a stack at one end of the frame during a filtering operation, and which are arranged to be moved one by one towards the opposite end of the frame to enable filter cakes to be removed from between the plates.The plates are heavy and tend to stick together, and known mechanism for moving the plates individually is either complex and tends to clog with the clay or like being filtered in ordinary usage, or fails to take account of the sticktion resulting in the press jamming.
