Ultrafiltration is a form of screening for the separation principle, to pressure-driven membrane processes, filtration precision 0.005-0.01μm range, can effectively remove the water particles, colloids, bacteria, organic bedding and high molecular substances . Can be widely used in material separation, concentration and purification. Ultrafiltration without phase transformation, room temperature operation, the separation of the heat-sensitive material is particularly suitable, and has good heat resistance, acid and alkali resistance and oxidation resistance, can be below 60 ℃, PH 2-11 conditions for the long-term continuous use.
Ultrafiltration membrane modules of the structure similar to the basic and reverse osmosis membrane can also be divided into the plate, tube, roll, hollow fiber type and so on.
