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 system for filtering solids includes a filtration tank for receiving a slurry containing the solids to be filtered. A filter assembly including a plurality of filter cells each having a filter medium at an exterior and a cavity at an interior is lowered into the filtration tank using a transport device carrying the filter assembly. A vacuum transfer system is connected to the filter assembly so as to transfer a vacuum to an interior of the filter cells. The vacuum transfer system is operable to perform the filtering and to retain the filtered solids while the transport device moves the filter assembly relative to the filtration tank.
