Abstract: A self-cleaning filter including a filter housing having at least a raw-liquid inlet and a clean-liquid outlet, a filter medium interposed between the raw-liquid inlet and the clean-liquid outlet At least one nozzle is located in proximity to the filter medium and is connectable to at least two different sources of pressure, one of which pressures is higher than the pressure prevailing in the filter, the other one being lower than the pressure prevailing in the filter There is also provided an arrangement to produce a relative movement between the filter medium and the at least one nozzle to the effect of having a substantial part of the surface area of the filter medium covered by the nozzle.

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.
