Abstract: A rotary disc filter is provided with a system for inhibiting biological fouling from biological growth on filters that form a part of the rotary disc filter. A biocide is pumped from a biocide supply tank to a manifold and mixed with a backwash to form a backwash-biocide solution. The backwash-biocide solution is sprayed onto filter media during a backwashing operation and the presence of the biocide inhibits and eliminates biological growth on the filter media.

Abstract: A method and apparatus for filtering a liquid from a liquid/solid mixture using a centrifuge. The centrifuge has a conveyor having a hub and a flight for imparting a centrifugal motion to the liquid/solid mixture. The conveyor is rotated for imparting the centrifugal motion. A filter is carried in the tank which holds the conveyor. The filter encircles the conveyor for filtering the liquid from the liquid/solid mixture. A backwash system has a tube having a series of nozzles positioned for spraying a fluid at the filter in a narrow band which circumscribes the filter. The tubing is connected to a header which projects out of the casing through an opening. The fluid sprayed through the nozzles is pumped through the header to the tubing having the nozzles. A cylinder is connected to the header for moving the header and the connected tubing longitudinally such that the nozzles move longitudinally along the filter for spraying the liquid against the filter in a narrow band distinct from a first narrow band by the relative movement of the nozzles to the filter. The fluid from the backwash system is at a force to counteract the centrifugal force of the mixture over the narrow band of the filter engaged by the spray. The fluid used for the backwash is the filtered liquid.

Abstract: A cylindrical plastic pipe is used as the sidewall of the rotary portion of the strainer. Apertures are drilled radially through the pipe, and one or more screen assemblies are circumferentially wrapped around the outside of and removably fastened to the pipe to cover the apertures. The central core of the strainer contains both supply and suction pipes. The supply pipe feeds cleaning and drive nozzles that are aimed at the pipe apertures. The cleaning nozzles are aimed radially for cleaning certain apertures. The drive nozzles are aimed tangentially toward a circumferential succession of other apertures near the bottom of the pipe to drive the rotary portion. In one embodiment the drive nozzles can rotate the rotary portion in either direction.

Abstract: A filter apparatus for separating solids from a liquid in a slurry, is cleaned by a jet and a sludge removal device. The filter is generally flat and has an inflow side on which the solids are deposited and an outflow side supported by a grid. The grid subdivides the outflow side into a plurality of separate injection chambers and defines a plurality of separate small regions of the filter material. The jet directs a stream of liquid through one of the injection chambers and against one of the small regions of the filter defined by the injection chamber. A cover plate is provided on the jet for engaging the grid to close one injection chamber opposite the filter material. The sludge removal device is located on the inflow side of the filter and is aligned with the jet to receive solids dislodged from the filter. The jet and sludge removal device more simultaneously and in alignment with each other to close selectively and to direct a stream of liquid through each of the injection chambers.
