ABSTRACT:
A filter plate which is longitudinally partitioned between its inlet and outlet ends, and features liquid feed and collection troughs at the respective ends. Such plates may be associated in opposed, relatively inverted pairs to form enclosed flow channels characterized by fluid flow rates 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 which may be usefully employed in the filter. The filter of the invention may be highly efficiently employed for dewatering of aqueous biomass suspensions, desalting of proteins, removal of secreted metabolites from cellular suspensions, and the like.
