More Information
Summary: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. Des procédés et systèmes de filtration permettent la séparation d'un flux de liquide à filtrer, au moyen d'un module de membrane de filtration ayant une pression transmembranaire uniforme, et d'un flux le long de la membrane, et le contrôle interne de l'encrassement de la membrane par une réduction périodique intermittente du différentiel de pression entre les côtés perméat et rétentat de la membrane et/ou des cycles de lavage à contre-courant pendant la séparation, la récupération, et/ou la purification de protéines, de peptides, d'acides nucléiques, de polymères d'origine biologique et d'autres composés ou matériaux à partir de fluides aqueux.
