UF(Ultrafiltration 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 0.001-0.1?m, Cut Off Molecular Weight(MWCO) from1000 to 500,000 Dalton.，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.

Mainly using materials of hydrophilic PS, the hollow fiber Ultrafiltration membrane made by Motian has excellent water permeability and acid and alkali resistance. The membrane has 3 layers structure, the inside and outside skins are thin separative layers and the interlayer is porous sponge supporting structure, which may effectively reduce the deep layer pollution of the membrane and increase the washing recovery efficiency of the membrane.
There are many varieties of membrane made by Motian according to the molecular weight cut-off, such as 6000, 10000, 20000, and 67000 dal. Customers may choose different pore size UF membrane according to the requirements of materials separation. There are also many types membrane modules with different sizes, such asФ90, Ф125, Ф160, Ф200, Ф225, Ф315, and etc.    Zhaojin Motian not only regard  the vendition but also think a lot of the Sustainable development of Ultrafiltration membrane.  Meanwhile, Motian may provide pilot test for customers and assisting engineering companies with design, system starting and a set of before and after sales services.
