ABSTRACT:
A filter (10) comprises a stack of flat rectangular filtrate-collecting chambers (12) defined by sheets (26) of stainless steel filter medium, and connected via respective thyristors (54, 58) to a power supply (50). Anode plates (14) are arranged between adjacent chambers (12). At intervals a current (of for example 1000A) is supplied to each chamber (12) in turn such that it is a cathode, for a short time sufficient to remove any fouling.
