1. Ultrafiltration membrane:

In the membrane separation technology, a filter membrane with a membrane pore size between 20×10-10m~1000×10-10m is called an ultrafiltration membrane, which is between 0.002-0.1μm, and the general colloid volume is ≥0.1μm, Latex ≥ 0.5μm, coliform, staphylococcus and other bacteria volume ≥ 0.2μm, suspended solids, particles, etc. volume ≥ 5μm, so the ultrafiltration membrane can filter out bacteria, colloids, suspended solids, proteins and other macromolecular substances in the solution.

2. Ultrafiltration use:

Ultrafiltration is usually used to prepare mineral water and mountain spring water. It is a process of separating impurities in liquid by using pressure as the driving force and using different pore sizes of ultrafiltration membranes. At present, in the water treatment industry, polysulfone and polypropylene hollow fiber types are the most used modules.
