The outer diameter and inner diameter of the hollow fiber are very small. The wall of the hollow fiber is covered with micropores. The pore size is expressed by the molecular weight of the substance that can be retained. The retained molecular weight can reach thousands to hundreds of thousands. The raw water flows under pressure on the outside or inner cavity of the hollow fiber, forming external pressure type and internal pressure type respectively. Ultrafiltration is a dynamic filtration process. The retained substances can be discharged with the concentrated water without clogging the membrane surface, and can operate continuously for a long time.
