Abstract
A liquid filtration system is provided which includes a traveling bridge carriage mounting air scour and backwash means within a single hood structure for successively cleaning each of a plurality of roughing filter cells and polishing filter cells formed in a filtration tank. The air scour means includes an air scour inlet conduit for supplying air under pressure to each cell. The backwash means includes a backwash conduit for creating suction within each filter cell. The single hood structure is adapted to sealingly engage each of the roughing and polishing filter cells. For the roughing filter cells, only an air scour operation is carried out while, for the polishing filters, backwash is done.
