ABSTRACT:
A web filter press for the removal of liquid from sludge having an upright converging filtering space into which sludge is received from above, a dandy roll at the bottom end thereof, and a horizontal roller train, in which the webs are progressively more deflected and compressed. A horizontal prefiltering run may be arranged ahead of the upright filter space, and suction boxes may be arranged in both of these runs to enhance their filtering efficiency.
