UF technology is a screening for the separation principle , to pressure-driven , membrane separation process to achieve mechanical separation , which is widely used in the separation of the solution , concentration and purification.

Hollow fiber ultrafiltration membrane is a polymer material using a special process of asymmetric semipermeable membrane made ​​of hollow capillary ( hollow fiber ) , wall clouds micropores. Liquid flowing on the outer membrane or film , under pressure , and small molecules through the membrane becomes ultrafiltrate . Which macromolecules ( proteins , various enzymes, nucleic acids , polysaccharides, etc. ) and colloids, bacteria and the like are left in the film , the solution becomes concentrated , thereby completing the separation of substances , concentration and purification .

Using ultrafiltration membrane to achieve separation of substances , concentration and purification has the following salient features:

A ultrafiltration process without no phase transition phase , room temperature operation , energy conservation, to isolate does not produce any pollution. For heat-sensitive material ( such as biological products, bacteria , proteins, etc. ) is particularly suitable for the separation .

B ultrafiltration membrane resistance to chemicals ability to adapt to a wide range of PH .

C ultrafiltration process is simple , easy to operate operation, less maintenance costs, cleaning simple.

D hollow fiber ultrafiltration membrane packing density, maximum filtration area per unit volume of the intima .

Ultrafiltration technology for its energy-saving effect is remarkable , simple equipment, easy to operate, easy to control and the advantages of being more widely used. Select the appropriate membrane separation process can be a true alternative to conventional drum filters , plate and frame filtration , centrifugation, solvent extraction, adsorption, regeneration, flocculation, copolymerization, precipitation, evaporation , and other conventional separation and filtration.

Ultrafiltration technology and other technologies integrated technology will replace largely traditional separation techniques currently used to achieve the skills consumption, improve product quality purposes, greatly promote the progress of science and humanity , contributed to community development. Membrane technology has been widely applied to the chemical industry . Petroleum and petrochemical, bio- chemical, environmental engineering, metallurgy , food , electronics, pharmaceutical, medical and many other industries .

Ultrafiltration process not only provides a very simple and effective way for the separation and purification of the solution , but also in urban domestic water , sewage, industrial wastewater treatment and reuse , desalination and other areas are also playing an increasingly important role.
