  • China UF Membrane Water Purifier Ultrafiltration

    Ultrafiltration water treatment equipment is a membrane separation process driven by pressure. Particles and impurities with a diameter of 0.002-0.1μm can be intercepted through the micropore screening on the membrane surface, which can effectively remove colloids, silicon, proteins, and microorganisms in the water.

  • Drinking water treatment by using ultrafiltration

    1996-8-1 · In this study we used two types of UF hollow fiber membranes-CA and PES-for drinking water treatment of river water. The UF perfor- mance was evaluated in terms of flux and quality of treated water. The CA membrane is hydro- philic, to which very low adsorption of substanc- es in raw water is expected.
