Sludge dewatering press - includes sludges receiving chamber contg. pressure piston, enabling braking up of caked sludge and draining of filtrate

摘要

Sludge dewatering press has a sludge receiving chamber contg. a pressure piston acting on the sludge, which is sepd. into volumes by flexible sepg. strands. The strands (5) consist of outer solids retaining layers (7) and a filtrate discharging layer (8), covered by at least one of the outer layers. Layers consist of woven or knitted cloth. The strands act at the same time as drainage strands. ADVANTAGE - Combined action of breaking up sludge cake and drawing off filtrate is obtd.
