ABSTRACT:
A method of and device for filtering liquids according to which the liquid to be filtered together with an auxiliary filter substance, e.g. Kieselguhr, is introduced into a filter tank including filter elements arranged in spaced superimposed relationship to each other and located on a filter shaft. The auxiliary filter substance, e.g. Kieselguhr, which has a flow and sedimentation speed settles on the filter elements while forming deposits which form filtering layers for the liquid to be filtered. The filtered liquid is withdrawn from the lower region of the filter tank. A transverse flow extending transverse to the sedimentation speed of the liquid to be filtered is superimposed upon the sedimentation speed including the auxiliary filter substance.
