Ultrafiltration

Ultrafiltration is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular solutions, especially protein solutions. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains.More specifically, it can refer to:* Ultrafiltration * Ultrafiltration cs:Ultrafiltracede:Ultrafiltrationfr:Ultrafiltrationpl:Ultrafiltracjapt:Ultrafiltraçãozh-classical:超濾法 Ultrasonography (From the Wikpedia article Ultrafiltration.)
