Abstract
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.
