UFc50C is capillary hollow fiber membrane made of high polymer material, which is a separating product that will not have any phase change. The modified PVC material adopted to this product has good permeable rate, good mechanical strength, good chemical resistance anti-pollution ability, MWCO is 100k Dalton. Membrane ID/OD is 1.0mm/1.8mm, filtering direction is inside-out, that is raw water flows inside the hollow fibers and, driven by differential pressure, permeates outwards so as to filter bacteria, colloids, suspended substances, microbes, and other harmful substances.
Production of mineral water, mountain spring water and other germ-free liquid;
Drinking treatment of tap water, surface water, well water and river water;
Pre-treatment of RO device;
Treatment, recycle and reuse of industrial wastewater
According to the service conditions of modified PVC hollow fiber ultrafiltration membrane which are applied to various water sources, the product is proved to reach below filtration effects:
Water Composition | Filtering Effect |
Suspended Substances, Particles >1um | Removal Rate ≥99% |
SDI | ≤ 3 |
Virus, Bacteria | >4 log |
Turbidity | <0.1NTU |
TOC | Removal Rate 0-25% |
Above data is obtained when turbidity of feed water is less than 15NTU. The product is proved to reach the sanitary standards of drinking water by Health Department of Guangdong Province. Approval number is YUE WEI SHUI ZI 2014S1671.
