Hollow fiber ultrafiltration membrane is an asymmetric membrane made of polymer material by special technology.It is hollow capillary tube wall with microporous, under the action of pressure and liquid flow inside the membrane, the solvent or small molecules can pass through the membrane, by collecting and become super filtrate, and one of the high polymer material (protein, nucleic acid, polysaccharide, etc.), and colloidal particles are stop on the membrane surface, was taken away by circulating fluid concentrate and be concentrate, so as to achieve the separation of matter, and the purpose of enrichment and purification.
The characteristics of ultrafiltration
1, ultrafiltration process no phase conversion, no heating, room temperature operation, energy saving, especially suitable for the separation of heat sensitive substances.Ultrafiltration process is simple, less supporting devices, simple operation and operation, low maintenance costs.
2. Ultrafiltration membrane is resistant to chemical erosion and has a wide range of PH adaptation.The ultrafilter has the largest membrane area per unit volume and the lowest investment cost. Please wash it easily.
3. The ultrafiltration process only USES pressure as the power of membrane separation, so the separation device is simple, short process, simple operation, easy to control and maintain.
