A dewatering screw press that separates liquid from solids — producing a dry, compact sludge cake.
CWG’s screw press is a dewatering press that separates liquid from solids. It works in a manner similar to the Archimedes’ screw, with the sludge travelling in the direction of the rotating screw. In this process the absorbed liquid filtrate (mostly water) is drawn out of the sludge, and the remaining sludge becomes solid and dried. The screw propagates the sludge to the end, where it exits into the discharge chamber as a dehydrated solid known as “sludge cake.”
The rotating screw continuously moves the filter cake along the press, drawing out filtrate while a defined residence time thickens the solids — minimising filter resistance and producing a consistent dry cake at the discharge.
