Hollow Fiber PVDF UF Membrane for WasteWater Treatment Plant
1. UF technology introduction
1.1.Ultrafiltration (UF) is a separation principle for screening, with pressure as the driving force to realize
mechanical separation membrane separation process, namely under certain pressure, when the mixed
solution of large molecules or a small molecule solute through the membrane surface, solvent
(e.g., inorganic salt) and small molecule solutes through the membrane, and the solute molecules due
to mechanical filtration membrane as concentrate intercept.
1.2.Ultrafiltration membrane products made by our company mainly include PES, PAN and PVDF membrane:
a.Polyethersulfone hollow fiber ultrafiltration membrane with acid and alkali resistance, high temperature resistance, high mechanical strength, resistance to cleaning and other advantages, widely used in the food industry, electroplating industry, pharmaceutical industry fermentation liquid separation and concentration, cathode electrophoresis paint recoveryand other fields.
b.Polyacrylonitrile membrane components with low prices, large water flux, pollution resistance and cleaning resistance, which is widely used in a variety of water treatment industries, especially the reuse of water and reverse osmosis water equipment pretreatment industries.
c.PVDF hollow fiber ultrafiltration membrane has strong anti-oxidation, anti-pollution and good cleaning performance, which is widely used in various sewage treatment industries.
