Working Principle
Sewage (or other raw water) passes through the front of the drum surface and flows into the drum, and flows out from the bottom. The suspended solids in the sewage remain on the rotating drum surface. The intercepted dirt is transported from the inlet end to the discharge end on the other side as the drum surface rotates, and is then removed by the discharge mechanism. A time relay controls the solenoid valve, which controls the cleaning system to regularly clean the drum surface.
