The ultrafilter is a purifier with high precision, good purification effect, long service life membranes. the membranes has Internal pressure and External pressure two models.
how to choose the membrane? if the water is not so dirty , the internal pressure membrane is good to choose ,it’s economical and practical. If the water is dirty , choose the external pressure membrane , also it’s called hand washing membrane , if the water is too dirty , should be chosen a pre-filter , to protect the ultrafilter membrane.
1.The principle and function of the PVDF Ultrafilter , using 0.01 micron ultrafiltration membrane separation technology, can effectively remove sediment, rust, suspended solids, colloids, bacteria, viruses, macromolecular organics and other harmful substances in water.
2. Advantages and disadvantages of the PVDF Ultrafilter: PVDF Ultrafilter has high filtering accuracy, the purified water is close to mineral water, and can drink directly . The flow is large, the filter element has a long service life, the internal pressure membrane filter can be automatically cleaned, no need electricity , not much waste water . the hand washing membrane filter is easy to take out and wash it regularly . The disadvantages are that the water purifier water treatment equipment removes scale, the water alkali effect is poor, the heavy metals in the water cannot be completely removed.
