65–340 m³/h Drum Screen Separator for Industrial Sewage


The 65–340 m³/h drum screen separator is a continuous mechanical screening system designed for fine solid liquid separation in wastewater treatment. It removes suspended particles larger than 0.25 mm using a rotating grid cylinder driven by a speed controlled motor. Wastewater is evenly distributed and filtered through the screen while solids are discharged automatically. It is widely used in industrial and municipal applications requiring stable, high efficiency pretreatment and reliable continuous operation.

Product introduction of 65–340 m³/h Drum Screen Separator

The 65–340 m³/h drum screen separator is an automatic wastewater pretreatment device designed for fine particle removal in industrial and municipal treatment systems. It is constructed from corrosion resistant stainless steel and equipped with a rotating grid cylinder driven by an AC variable speed motor and reducer system. Wastewater enters through a buffer distribution chamber, allowing uniform flow before passing through the screen. Solids larger than 0.25 mm are intercepted and discharged, while filtered water flows to downstream processes. It is suitable for industries requiring stable screening performance and reduced organic and fiber load before biological treatment.

Working principle

Wastewater enters the unit through an inlet valve into a buffer distribution chamber, where flow is stabilized and evenly distributed. The liquid then contacts the rotating grid cylinder driven by a variable speed motor and reducer system.

During rotation, water passes through the grid openings while suspended solids larger than 0.25 mm are retained on the screen surface. A cleaning mechanism removes accumulated solids to maintain permeability.

Separated solids are discharged into a collection hopper, while filtered water is directed to downstream treatment units. The process operates continuously under controlled hydraulic and mechanical conditions.
