ABSTRACT:
A completely new type of filtration system uses a traveling plenum that travels through granular filtration media in a filter tank and backwashes a portion of the media a little at a time. A pump forces backwash water into the traveling plenum, and porous plates mounted on the top of the plenum allow the water to come to the surface of the media and loosen solids deposited at the surface during a filtration cycle. A washwater hood and waste water pump removes the loosened solids from the surface of the media. Porous plates mounted on the sides of the traveling plenum allow backwash water to fluidize surrounding media and promote the transportation of the traveling plenum in the media. Thus, filter construction is reduced to creating a tank with influent and effluent openings without the complicated cell and plenum construction of conventional traveling bridge filters. Effluent plugs, installed across effluent openings, are designed to allow water to exit the tank but retain media inside the tank. The traveling plenum filter maintains the advantages of the low flow rates and low volumes of backwash water commonly found in traveling bridge filter systems.
