Rotary Drum Filter Screen
Rotary Drum Filter Screen
The Rotary Drum Filter Screen is a wastewater pre-treatment system that removes solids, fibres, and debris. It combines screening, washing, conveying, and dewatering into one continuous, automated process, reducing the need for manual work. As water flows through the rotating drum, solids are captured and moved for discharge. An automatic backwashing system keeps the screen clean and prevents clogging. Its compact, all-in-one design saves space and makes installation easy in both new and existing facilities. Built from corrosion-resistant materials, it is durable and reliable, making it a cost-effective solution for wastewater treatment.

Features
Standard Features
- Stainless steel construction (SS304/SS316) for corrosion resistance and long service life
- Integrated screening, washing, conveying and dewatering functions
- Chain-driven drum system for stable and efficient operation
- Automatic backwashing system for continuous self-cleaning
- Optimised flow distribution for uniform hydraulic loading
- Dual overflow protection to minimise splashing and improve hygiene
- Flexible installation options (channel-mounted or tank-installed)
Options & Accessories
- Screen type selection:
- Wedge wire screen (0.5–6 mm)
- Perforated plate (1–6 mm)
- Custom drum diameters (up to 3000 mm) for project-specific requirements
- Variable speed drive for process optimisation
Working Principle
The Rotary Drum Filter Screen operates as a continuous mechanical separation system designed for wastewater pre-treatment. Wastewater enters the inlet chamber and is evenly distributed across the rotating drum surface. As the drum rotates, liquid passes through the screen openings while suspended solids are retained on the inner or outer surface, depending on configuration. Captured solids are transported along the drum by rotation and discharged via a screw or scraper mechanism. An automatic backwashing system continuously cleans the screen surface, preventing clogging and ensuring reliable operation.
Key Benefits
- High-Efficiency Solid Removal
Effectively captures suspended solids, fibres, and debris using precision wedge wire or perforated screens, improving downstream treatment performance. - Fully Automated Operation
Integrates screening, washing, conveying, and dewatering into a continuous automatic process, reducing manual intervention. - Reliable & Stable Performance
A chain-driven system and optimised flow distribution ensure consistent operation under varying hydraulic conditions. - Anti-Clogging Design
Equipped with an automatic backwashing system to prevent screen blockage and maintain filtration efficiency. - Compact & Space-Saving
All-in-one design reduces footprint and simplifies installation, making it ideal for both new and existing installations.
