Abstract: A filter press for the filtration of suspensions has a frame, a support plate (1), a pressure plate (2) mounted in the frame and a set of vertically arranged filter plates (4) between the support plate (1) and the pressure plate (2). The filter plate (4) is provided with a single layer filter fabric (8) on the side that removes the liquid and collects the solids. The filter fabric runs over two filter cake removal rollers (6, 7) that are so positioned relative to each other and relative to the fabric (8) that an S-configuration is imposed on the filter fabric (8) as the rollers travel along the fabric. A pressure application device (5) presses the filter plates (4) together. A cleaning pipe (17) with spray nozzles (17A) for cleaning the filter fabric (8) is positioned between the cake removal rollers. The single layer fabric reduces the filtering resistance, thereby increasing the capacity of the filter press.
