Rotating Drum Screen Separator for Wastewater Treatment
The rotating drum screen separator is a high-efficiency wastewater fine screening system designed for continuous solid-liquid separation. It is widely used in municipal and industrial wastewater treatment, including food processing, paper mills, and urban sewage systems. The equipment effectively removes scum, fibers, and suspended solids from water intake, providing reliable pretreatment performance with low hydraulic loss and stable operation in high-capacity applications.

Product introduction of Rotating Drum Screen Separator
The rotating drum screen separator, also known as a rotary drum fine screen or wastewater drum filtration system, is designed for precise solid removal in wastewater pretreatment processes.
Wastewater enters the rotating drum at an inclined angle, where fine mesh screening elements intercept suspended solids. The system integrates screening, lifting, washing, and dewatering functions into one continuous operation.
It is suitable for high-precision wastewater treatment applications requiring small screen gaps and stable hydraulic performance.
Working principle
The rotating drum screen separator operates at an inclined angle of approximately 35 degrees.
Wastewater flows into the rotating drum, where fine mesh screens intercept suspended solids, fibers, and scum. As the drum rotates at a constant speed, solids are continuously lifted, washed, and transported by a spiral mechanism.
A built-in spray nozzle and nylon brush system remove debris from the screen surface, ensuring self-cleaning performance. The dewatered solids are then discharged into a container or conveyor system.
This continuous process ensures stable filtration and odor-free operation.
