Screw Drum Screen (SDS)
The Screw Drum Screen (SDS) is a pre‑treatment wastewater equipment designed for the mechanical separation of coarse suspended solids from liquid streams.By combining a rotary drum screen with an internal screw conveyor, this unit enables continuous solid separation, dewatering, and automatic discharge, while effectively protecting downstream equipment.
Advantages
- Efficient removal of coarse solids (>500 microns)
- Fully automatic, continuous operation
- Integrated screening, conveying, dewatering and compaction in one unit
- Compact design with low space requirement
- Automatic screen cleaning to prevent clogging
- Reduced wear on downstream pumps and equipment
- Lower operation and maintenance costs
Applications
- Municipal and industrial wastewater treatment plants
- Livestock and poultry slaughterhouses
- Food processing and agricultural industries
- Pulp and paper mills
- Recycling and solid waste management facilities
- Glass manufacturing and similar industries
