Screw Screen

About Screw Screen

Efficient Screening & Solids Separation for Wastewater Treatment

The Screw Screen is an efficient mechanical screening system designed to remove coarse and fine solids from municipal and industrial wastewater streams before downstream treatment processes. It combines screening, conveying, and dewatering in a single compact unit, making it an ideal solution for wastewater treatment plants where reliable solids removal and reduced manual handling are required.

The system captures suspended and floating solids on the screening surface while a rotating screw conveys the retained material toward the discharge point. The continuous operation helps maintain consistent screening performance while reducing the need for frequent manual cleaning.

Effective Removal of Waste Solids

The Screw Screen efficiently separates materials such as plastics, rags, fibres, paper, food waste, packaging materials, and other screenings from incoming wastewater. Removing these solids at the preliminary stage helps protect pumps, pipelines, biological treatment systems, and other downstream equipment from clogging and damage.

Continuous Screening & Conveying

The integrated screw mechanism continuously transports captured solids from the screening zone toward the discharge area. This provides smooth and controlled solids handling while minimizing manual intervention and improving overall plant operation.

Reduced Manual Handling

Unlike conventional manually cleaned screens, the Screw Screen is designed for automated or continuous solids removal. The collected screenings are conveyed directly toward the discharge point, reducing operator involvement and improving workplace cleanliness and safety.

Efficient Solids Dewatering

Depending on the configuration, the conveying section can provide screenings compaction and dewatering before discharge. This helps reduce the moisture content and volume of removed solids, making subsequent handling, transportation, and disposal easier.

Robust & Customizable Construction

The Screw Screen can be manufactured using suitable SS304, SS316, or other materials of construction depending on wastewater characteristics and project requirements. Screen opening, screw diameter, length, capacity, inlet/outlet arrangement, and mounting configuration can be customized according to the application.
