ABSTRACT:
A filter-plate assembly has a backing wall having an outwardly directed face and formed with an annular groove opening outward at the face and of a predetermined transverse width and a filter plate adjacent the wall and having an outer peripheral frame set in the groove and of a width substantially less than the width of the groove so as to define therewith an outwardly open annular gap. A generally planar central panel within the frame has a back face turned toward and forming a compartment with the wall and a front face turned away from the wall and adapted to be overlain by a filter cloth. A retaining bar is set in the space and braced transversely between the frame of the element and the backing wall.
