Rotary Drum Screen – Industrial Rotary Screen for Wastewater Treatment
Rotary drum screen is a highly efficient mechanical filtration system designed for continuous solid-liquid separation in industrial and municipal applications. It is widely used in wastewater treatment, food processing, and industrial filtration systems.
The system consists of a rotating cylindrical drum made from wedge wire or perforated screen, which allows water to pass through while retaining solid particles. As the drum rotates, accumulated solids are automatically removed, ensuring continuous operation with minimal maintenance.
Compared to traditional static screens, rotary drum screens offer higher efficiency, automatic cleaning, and stable performance, making them an essential solution for modern filtration systems.
At WireMeshi, we provide high-performance rotary drum screens with wedge wire screen cylinders, engineered for durability, precision, and long-term operation.

Structure & Components
A rotary drum screen typically includes:
- Wedge Wire Screen Drum
Core filtration component with precise slot openings - Drive System (Motor & Gearbox)
Controls rotation speed and operation - Spray Cleaning System
High-pressure water cleans the screen surface - Frame & Housing
Provides structural support and installation base - Discharge System
Removes separated solids automatically
Working Principle
The rotary drum screen operates through a simple but effective process:
- Wastewater flows into the drum
- Water passes through the screen slots
- Solids are trapped on the surface
- Drum rotation lifts solids upward
- Spray system cleans the screen
- Solids are discharged into collection system
This continuous cycle ensures efficient separation with minimal downtime.
