The Rotary Drum Screen is a high-efficiency solid-liquid separation device designed to continuously and automatically remove suspended solids and debris from water. Rotating drum screening provides precise filtration, stable operation, and minimal maintenance, making it ideal for municipal wastewater, food processing, paper, and chemical industries.
Working Principle
The influent water flows either from the inside or outside of the rotating drum. Solids are trapped on the screen surface while water passes through the openings. As the drum rotates, the collected debris is carried upward and automatically removed by a high-pressure spray or scraper. The waste falls into a conveyor or bin, and the entire process runs continuously with full automation.
Main Components
Rotary Drum: Made of wedge wire or perforated plate, high accuracy and durability
Frame: Stainless steel structure, rigid and corrosion-resistant
Drive Unit: Gear motor ensures stable drum rotation
Cleaning System: High-pressure spray or scraper for automatic cleaning
Trough & Discharge Port: Collects clean effluent and discharges solids
Control System: PLC control with optional pump interlock
Key Features
Compact design with small footprint and easy installation
High screening precision and interception efficiency
Automatic cleaning maintains continuous operation
Low noise, low energy consumption, and minimal maintenance
Fully automatic and unattended operation
All stainless steel construction ensures long service life
Applications
Municipal and industrial wastewater pretreatment
