Raw water fills into the inner distributor through the inlet, and disctributed to the inner grille screen surface after steady. Clean water pass through the grille screen vertically for efficient filtration. While solids are intercepted by the screen and delivered by the inner rotary guide plates to the drainage valve. Rotary drum grille has a flushing nozzle outside the grille cylinder, clean water through the fan-shaped nozzle begins backwashing the grille cylinder under the water pressure of 0.3MPa. Dirty water after backwashing concentrates to the bottom collecting tank, and discharged.
