Ultrafiltration membrane has been widely used in industry and has become one of the new chemical unit operations. For separation, concentration and purification of biological products, medical products and food industry; It is also used in terminal treatment devices for blood treatment, waste water treatment and ultrapure water preparation.

Hydrophilic ultrafiltration membrane

Life cycle of ultrafiltration membrane:

The chemical cleaning cycle of hydrophilic ultrafiltration membrane is longer, and the chemical cleaning recovery is better. In each chemical cleaning cycle, the flux recovery after backwashing is close to 100%. The chemical cleaning cycle of non-hydrophilic ultrafiltration membrane is short, and the flux recovery after backwashing within each chemical cleaning cycle is only 80-90%. Therefore, in water treatment engineering, hydrophilic ultrafiltration membrane has obvious advantages over non-hydrophilic ultrafiltration membrane, which can maintain a stable flow rate -- design flow rate -- well in its service life
