Rotary Drum Screens
Reliable Solids Separation. Purpose-Built for Your Process.
Chandco’s Rotary Drum Screens are engineered for continuous, high-efficiency solids separation in municipal and industrial wastewater treatment. Each unit is constructed from 304 or 316 stainless steel and custom-built to suit your flow volume, solids concentration, discharge layout, and available footprint. The internally fed design maximizes screening efficiency while minimizing maintenance. Built for durability in corrosive environments, these screens are ideal for primary screening or pre-treatment and integrate seamlessly into both new and existing systems.
Key Features & Performance Advantages
- Engineered Unibody™ Construction
Fully welded 304 or 316 stainless steel body ensures structural integrity and long-term durability in corrosive environments. - Internally Fed Drum Design
Maximizes screening surface area and promotes even influent distribution for efficient solids separation. - Interchangeable Screen Panels
Slide-in woven wire or perforated panels (17 microns and up) allow for fast, tool-free replacement and minimal downtime. - Variable Speed Chain Drive
Adjustable rotation (2–10 RPM) provides process flexibility and accommodates varying flow conditions. - Spray-Back Cleaning System
Automated backwash system maintains screen performance and reduces manual cleaning requirements. - Self-Draining Headbox
Prevents pooling and supports even influent flow across the drum surface. - Optional Solids Discharge Screw
Transfers retained solids to a chute or compaction system, enabling continuous operation. - External Access to Components
Maintenance points are externally accessible, minimizing service time and improving safety. - Compact & Modular Footprint
Easily integrates into tight or retrofit installations. Scalable to match capacity needs. - Control Panel Integration (Optional)
Available with standalone or SCADA-compatible panels for automated cleaning and alarm functions.
Industries & Applications
- Municipal Wastewater Treatment
Used in headworks and lagoons to remove solids at the front end of the treatment process. - Food & Beverage Processing
Screens waste streams from meat, dairy, brewing, and other production lines before discharge. - Meat & Poultry Facilities
Removes organic solids, fats, and proteins prior to biological or chemical treatment. - Pulp & Paper Mills
Captures fibrous waste and debris in process water and final effluent streams. - Industrial Process Water
Handles high-load industrial discharge, protecting downstream equipment and improving treatment efficiency. - Automotive & Equipment Washes
Removes debris, grease, and solids from vehicle and parts washing systems. - Pre-Membrane & Pre-DAF Screening
Improves efficiency and reliability of downstream DAF or membrane filtration systems.
