Abstract
A ceramic filter plate (22) is provided with a conductive wiring (70, 71) extending along the filter plate to form a continuous electrical circuit and arranged to break upon breakage of the filter plate. The integrity of the conductive wiring (70, 71) is monitored, and the operation, particularly the rotation, of the disc filter is immediately stopped upon detecting a break of the conductive wiring.
