Low operating cost: Under the same operating conditions, high performance hollow fiber ultrafiltration membrane has lower transmembrane operating pressure, can maintain low pressure and high throughput for a long time, and the backwashing cycle can be extended by more than 50%. It has obvious advantages of water saving (saving backwashing water), medicine saving (saving chemical backwashing agents, reducing secondary pollution to the environment), energy saving (reducing power consumption of pumps).

 

Low pressure and high flux: Under the same transmembrane pressure, the solution flux of high performance hollow fiber ultrafiltration membrane increased by more than 30%. It has outstanding performance in the measurement of porosity, pore size, pore size distribution and standard pure water flux.

 

Good anti fouling ability: as the high performance hollow fiber ultrafiltration membrane has a strong hydrophilic group on the surface, the hydrophilicity of the hollow fiber ultrafiltration membrane has been greatly improved. Its contact angle is less than 43 degrees, which reduces the pollution caused by hydrophobic pollutants. The enhanced hydrophilicity of the membrane makes it difficult to contaminate the membrane for a long time, even if the gel layer is polluted. Cleaning can be applied to the treatment of highly polluted wastewater. as the high performance hollow fiber ultrafiltration membrane has a strong hydrophilic group on the surface, the hydrophilicity of the hollow fiber ultrafiltration membrane has been greatly improved.
