Screw Sludge Dewatering Machine

In simple terms, a dewatering screw press separates liquids from solids. It is a device that moves slowly, dewatering sludge through a gravitational process. A screw press is used for material that is hard to dewater, including materials that pack together.The purpose of sludge dewatering is to reliably and efficiently concentrate the wastes into high solids filter cakes for easy and cost-effective disposal. Disposal of sludge is governed by strict regulations.A screw with a variable pitch helix operates within a cylinder of fixed and moving rings that make up the dewatering drum. The fixed rings form a static structure whereas the moving rings ensure continuous self-cleaning while the screw is in motion. The gap between the fixed and moving rings varies from 0.5 to 0.1 mm.
