Applications
●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.
Filtration Performance
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 2014?S1671.
