The hollow fiber ultrafiltration membrane we offer adopts modified PVDF as raw material. The PVDF is processed with hydrophilization treatment; our HF membrane for ultrafiltration has higher water flux and better antifouling property. MEMFILL has various types of membrane which has different molecular weight cut off (MWCO) up to ~100,000 Dalton; Our product can be used for the removal of microorganism, colloids, algae and other impurities that may cause turbidity Good anti-fouling performance, high water flux, stable permeate water production, long service life; Outside-in filtration or Inside out type is possible, it can stand bad water quality condition Combined air and water backwash together, high flux recovery rate, so easy to clean Excellent chemical stability and high antioxidant ability Low-pressure operation; save electricity and energy. Operation pressure 0.30 MPa
