摘要： A filtration cassette including a multilaminate array of sheets including filter sheets alternating with permeate sheet members and retentate sheet members, and a cross-flow filter device comprising a multiplicity of stacked filtration cassettes of such type. The improvements associated with the filtration cassettes described herein include, but are not limited to, at least one of: reinforced inlet(s) providing for longevity and improved cleanability of the cassettes; spacer permeate screens to limit throughput restriction; stainless steel or otherwise stiffened permeate sheets to prevent movement and increase flux; and stainless steel permeate sheets that can be used with ultrasonic transmission to minimize fouling of the filter sheets and extend cleaning cycles. Advantageously, the filtration cassettes are more resistant to higher temperatures than the filtration cassettes of the prior art.

摘要： The present invention relates to modification to permeate channels and permeate materials in a cross-flow filtration system to improve performance in counter current filtration having both retentate channels and permeate channels wherein a solution is pumped through one of the channels and drawn through a membrane to one of the other channels to assist in positive pressure driven filtration by using the osmotic pressure, concentration, or preferential solubility difference between the retentate and permeate flow streams thereby increasing or altering the flux through the membrane separating the flow streams.
