ABSTRACT:
A filter element for a filter apparatus comprises a rigid support plate on at least one side of which is spanned a generally square filter cloth. This filter cloth may be formed as a pair of panels joined permanently together on three sides so as to form a pocket and having a fourth side which can be closed by a clamp or the like. The support is slipped into the pocket and a plurality of such filter elements are spaced along a rotatable hollow shaft centered in a filter chamber to which a solution to be filtered is fed. During operation the filtrate is pumped out of the hollow shaft through the filter cloth on which filter cake deposits. For cleaning of the cloth the shaft is rotated and the filter cake is washed off with a liquid spray.
