Product Overview
The Screw Screen by ArCh Enviro is a compact and highly efficient mechanical screening device designed for wastewater treatment applications. It integrates three key functions: screening, conveying, and compacting, all within a single, space-saving unit.
Ideal for small to medium flow rates, the Screw Screen effectively captures solids like rags, plastics, and paper from municipal and industrial wastewater streams. Its robust, stainless steel construction ensures long service life and reliable performance even in demanding environments.
This equipment is part of our broader Screening Solutions portfolio, engineered to support modern effluent treatment requirements.

Working Principle
Wastewater flows through a fine screen where solids are retained. A screw conveyor integrated behind the screen transports and compacts the solids toward the discharge point. The screen is cleaned by brushes fixed on the screw flight, ensuring efficient screening with minimal clogging.
