Aqua Aerobics – AquaDisk™ Cloth Media filter offers tertiary filtration with low footprint where clarified effluent enters the filter and flows by gravity through the cloth media of the stationary hollow disks. The filtrate exits through the hollow shaft which supports the individual disks and flows to the effluent channel. As solids accumulate on the surface of the media, the water level surrounding the disks rises. Once a predetermined level is reached, the disks rotate and the media surface is automatically vacuum backwashed clean. Heavier solids settle to the bottom of the tank and are then pumped to a sludge tank or to the plant headworks.
Why Cloth Media?
It’s not just “hydraulic loading” rate, but also “solids loading” rate that matters for an effective Tertiary Device (especially when filtering TSS and precipitated phosphorus solids).
