Abstract

A sludge volume of difficult to dewater sludge is subdivided in a sludge dewatering press into fractional volumes which are self-draining even at press pressures of 50 bar and more. The partitions are water-permeable and form water channels for conducting the expressed liquid away from the sludge volume.
