摘要: Filtration processes and systems are provided for the separation of a filterable fluid stream by a filtration membrane module with uniform transmembrane pressure and flux along the membrane and internal control of membrane fouling via intermittent periodic reduction of the pressure differential between the permeate and retentate sides of the membrane and/or backwashing cycles during separation, recovery, and/or purification of proteins, peptides, nucleic acids, biologically produced polymers and other compounds or materials from aqueous fluids.
