FILTERING - Inlet wastewater enters the tank or basin, completely submerging the cloth media. By gravity, liquid passes through the cloth media. As solids accumulate on
and within the media, a mat is formed and the liquid level in the tank or basin increases. The filtered liquid enters the internal portion of the disk where it is directed to final discharge through the center shaft.

BACKWASH - At a predetermined level or time, the backwash cycle will be initiated. Solids are backwashed from the surface by liquid suction from both sides of each disk. During backwash, disks are cleaned in multiples of two, unless a single disk unit is utilized. Disks rotate slowly, allowing each segment to be cleaned. Backwash water is directed to the headworks. Filtration is not interrupted during this cycle.

SOLIDS WASTE - The filtration process requires no moving parts. Heavier solids are allowed to settle to the bottom portion of the filter tank. These solids are then pumped on an intermittent basis back to the headworks, digester or other solids collection area of the treatment plant.
