A filter plate which is longitudinally partitioned between its inlet and outlet ends, and features liquid feed and collection troughs at the respective ends which are of progressively decreasing depth from the medial part of the trough to the extremities thereof. 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 in 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.

A filter plate having a generally planar and rectangular shape with a substantially flat bottom surface, and a top surface with an upwardly extending wall circumscribingly bounding a flow channel of generally rectangular shape with said top surface bounded by said upwardly extending wall comprising a top surface bounded by said upwardly extending wall comprising a floor of said flow channel, with a liquid inlet port at a medial part of a first side of said flow channel and a liquid outlet port at a medial part of a second side of said flow channel opposite said first side thereof, said liquid inlet port being joined in liquid flow communication with a liquid feed trough extending transversely across said first side of said flow channel, and said liquid outlet port being joined in liquid flow communication with a liquid collection trough extending transversely across said second side of said flow channel, with a plurality of spaced-apart partitions extending upwardly from the floor of said flow channel between said liquid feed trough and liquid collection trough, said partitions being of lesser height than said wall circumscribing said flow channel and substantially parallel to one another to define a series of sub-channels extending longitudinally between said liquid feed trough and said liquid collection trough, said liquid feed trough being of progressively decreasing depth from its medial portion, in communication with said liquid inlet port, to its marginal extremities, and said liquid collection trough being of progressively decreasing depth from its medial portion, in communication with said liquid outlet port, to its marginal extremities.
