Ultrafiltration membrane filter

Hollow Fiber UF membrane is an asymmetric semi-permeable membrane made of high molecular chemical material by special technology. It presents hollow capillary tube shape (or hollow fiber shape), micro-pore covers tube wall densely. Feed liquid is flowing in or out the membrane under the influence of pressure, dissolvent or small molecular can permeate membrane and become product liquid by collection, while large molecular (protein, each kind of enzyme, nucleic acid, polysaccharide and so on) colloid particle (such as emulsion, micro-ion) and bacterium are cut off of the membrane and are taken off by the circulating flowing feed liquid to become concentrating liquid. That is the process of separating, concentrating, and purifying substance.
