摘要： A liquid filtration system is provided which includes a traveling bridge device mounting air scour and backwash means for successively cleaning each of a plurality of filter cells formed in a filtration tank. The air scour means includes a first hood open to atmosphere and adapted for sealing engagement with each filter cell. The first hood may include an air scour inlet conduit for supplying air under pressure to each cell. The backwash means includes a second hood also adapted for sealing engagement with each filter cell and includes a backwash conduit for creating suction within each filter cell. In one embodiment where the air scour pump is mounted on the traveling bridge carriage, each cell is provided with a vertical riser adapted for sealing engagement with the air scour inlet conduit in the air scour hood. In an alternative arrangement, the air is supplied from a ground installed pump, through a common inlet manifold, to the individual cells. In this embodiment, the air flow is regulated by valves located externally of each cell, and successively actuated by a control arm mounted on the carriage.

摘要： A liquid filtration system is provided which includes a traveling bridge device mounting and backwash means for successively cleaning each of a plurality of filter cells formed in a filtration tank. Both surface wash and backwash means are included in a single hood structure adapted to sealingly engage each filter cell, successively, as the traveling bridge carriage traverses the tank. The surface wash means includes a surface wash conduit for supplying liquid under pressure to the upper surface layer of each cell. The backwash means includes a backwash conduit for creating suction within each filter cell.
