HOLLOW FIBER UF MEMBRANE |
Hollow Fiber Ultrafiltration 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. The pore size of the UF membrane is about 0.001-0.1μm, Cut Off Molecular Weight(MWCO) from1,000 to 500,000 Dalton. Feed liquid is flowing in or out the membrane under the influence of pressure, dissolvent or small molecule can permeate membrane and become pure liquid by collection, while large molecule (protein, each kind of enzyme, nucleic acid, polysaccharide and so on) ,colloid particle (such as emulsion, micro-ion) and bacterium are cut off by the membrane and are taken off by the circulating liquid flow to become concentrating liquid. That is the process of separating, concentrating, and purifying substance;
The pore size of the UF membrane is about 0.001-0.1μm, Cut Off Molecular Weight(MWCO) from1,000 to 500,000 Dalton;
This type of synthetic membrane is made of high molecular chemical material by special technology, with an asymmetric pore structure ( A thin membrane with tight pores backed by one or several thicker membrane with wider pores).
The molecular weight cut-off is a specification commonly used to describe the retention capabilities of UF membrane and refers to the molecular mass of a solute where the membranes have a nominal rejection;
The MWCO specification is most commonly used to characterise ultrafiltration membrane;
Inside-out (Internal pressure)
Feed liquid enters the center of hollow fiber, the colloid, Suspended solids, bacterium and other macromolecule substances are intercepted by fiber inner wall and turn into concentrate, while water molecule and ion permeate fiber wall, and is collected at fiber outer wall and becoming pure liquid;
Outside-in (External pressure)
Feed liquid pass through hollow fiber outside into inside, the colloid, Suspended solids, bacterium and other macromolecule substances are intercepted by fiber outer wall and turn into concentrate, while water molecule and ion permeate fiber wall, and is collected at fiber inner wall and becoming pure liquid;
