ABSTRACT:
A filter plate having a flow channel area on its main top surface, and liquid distribution and collection basins, each of polygonal shape, on its main bottom surface. Liquid inlet and discharge trough openings extend through the plate adjacent the respective distribution and collection basins, to commnicate the basins on the main bottom surface of the plate with the flow channel area on the main top surface thereof. Such plates may be associated in opposedly facing pairs to form enclosed flow channels characterized by fluid flow patterns which are substantially uniform across the full transverse extent of the flow path and which facilitate the utilization of the full areal extent of the filter media employed therewith. Also described is a unitary filter element support which may be usefully employed in the filter. The filter of the invention may be advantageously employed for dewatering of aqueous biomass suspensions, desalting of proteins, removal of secreted metabolites from cellular suspensions, and the like.
