Ultrafiltration membrane filtration with pressure difference as the driving force was adopted.Ultrafiltration membranes are mostly made of acetate fibers or polymer materials with similar properties.It is most suitable for the separation and thickening of solutes in the treatment solution, and it is also often used for the separation of colloidal suspensions, which is difficult to be completed by other separation techniques.
Membrane filtration driven by pressure difference can be classified into ultrafiltration membrane filtration, microfiltration membrane filtration and reverse osmosis membrane filtration.They are distinguished by the smallest particle size or molecular weight that the membrane can trap.When the rated pore diameter range of the membrane is taken as the distinguishing standard, the rated pore diameter range of the microporous membrane (MF) is 0.02~10 microns.UF ranged from 0.001 to 0.02 microns.Reverse osmosis membrane (RO) is 0.0001~0.001 muon.It can be seen that ultrafiltration membrane is most suitable for the separation and thickening of solute in solution, or for the separation of colloidal suspension which is difficult to be completed by other separation techniques.The technique of making ultrafiltration membranes, i.e. obtaining the desired size and narrow distribution of micropores, is extremely important.For example, ultrafiltration membranes with different pore sizes and pore size distribution can be obtained according to the type and concentration of solution, evaporation and condensation conditions.Ultrafiltration membrane is generally a polymer separation membrane, used as ultrafiltration membrane polymer materials are mainly cellulose derivatives, polysulfone, polyacrylonitrile, polyamide and polycarbonate.
Ultrafiltration membrane is widely used in food industry, pharmaceutical industry, etc. It can be used for concentrated purification of drugs, fruit juice, milk products, purified water, mineral water purification, etc. Ultrafiltration equipment has the characteristics of good filtration effect, large water yield and strong stability.
