ABSTRACT:
A process for filtering a fluid is provided. The process includes providing a filtration cell having a filter membrane, a base configured to receive filtrate passing through the membrane, and a flow channel open to the filter membrane. A flow of the fluid is provided through the flow channel substantially tangent to the filter membrane in a first direction and a second direction substantially opposing the first direction, whereby the fluid reciprocally flows across the filter membrane. Filtrate passing through the membrane is collected. A system for filtering a fluid is also provided.
