What Is a Screw Press?
A screw press is a mechanical sludge dewatering device that uses a slowly rotating screw within a cylindrical or ring-disc screen to separate water from sludge.
How Does a Screw Press Work?
Learn how a screw press works: from polymer conditioning and flocculation through thickening, dewatering, and cake discharge.
Screw Press Working Principle
Detailed explanation of the screw press working principle: screw conveyance, filtration, pressure build-up, and cake formation.
Multi-Disc Screw Press
Multi-disc screw press technology uses alternating fixed and moving ring discs for clog-free, self-cleaning sludge dewatering with minimal maintenance.
Self-Cleaning Screw Press
Self-cleaning screw press technology uses moving ring discs to continuously clear filtration gaps, eliminating clogging and reducing maintenance.
Sludge Thickening and Dewatering
Combined sludge thickening and dewatering in a single screw press unit eliminates the need for separate thickening equipment.
