ABSTRACT:
A filtration cassette, of a type comprising membrane filter sheets arranged in a peripherally bonded array of multilaminate character wherein the filter sheets alternate with foraminous (e.g., screen or mesh) sheet elements, and a cross-flow filter comprising a multiplicity of stacked filtration cassettes of such type. The filtration cassettes and 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.
