ABSTRACT:
The thickness of filter plates is a parameter determining the size of the useful volume of filter presses.
It is desirable to provide a filter plate which can be dimensioned substantially thinner than heretofore and which moreover can be manufactured in supersize dimensions of, for example, an edge length of 3 m.times.3 m. To provide for high stability and a certain flexibility thereby enabling in a manufacturing of very large filter press plates having relatively thin bottom portions, the bottom portions of the filter plate is divided into at least four quadrants with each of the quadrants including outwardly curved portions, and with the outwardly curved portions of adjacent quadrants being in opposite directions with respect to a center plane of the filter plate.
