    Rotary Drum Precision Filter

    The rotary drum precision filter is composed of equipment structure module, filter module, driving system, backwashing system and automatic control system. After the sewage enters the equipment, the automatic control system starts the driving system to drive the drum to rotate, and starts the backwashing system at the same time. Under the action of gravity, the sewage flows out of the drum from the drum, and the suspended solids in the water are intercepted in the drum by the filter screen. The drum rotates slowly, and the backwash pump draws filtered water to backwash the filter screen. The washed dirt falls into the collection tank inside the drum and is discharged outside the equipment through the blowdown pipe.
