Internally Fed Rotary Drum Filter Screen

Short Description:

The internally fed rotary drum screen is a reliable and efficient solid-liquid separation device designed for industrial and domestic wastewater treatment. It is capable of removing solid particles larger than 0.2 mm. Wastewater enters the drum through the feed inlet, flows over the distribution weir, and passes onto the inner drum surface. As the drum rotates, solids are retained on the screen surface while liquids pass through the mesh, enabling continuous separation.
