UF filters
Modified hydrophilic PVC membrane characteristics:
Modified hydrophilic hollow PVC fibers (UF membranes), has been modified through hydrophilic and materialization treatment. These fibers have the advantages of low energy consumption, high flux, high antipollution, high mechanical strength and toughness. At the same time, they are optimized by the making membrane formula, which have good resistance of acidity and alkalinity, oxidability, ageing and bacteriostat
UF membranes have stable MWCO, its surface is smooth, easily to wash, and has a high flux recovery rate
UF membranes are widely used in the underground water, surface water, middle water/waste reuse, seawater desalinization and other water treatment process flow and concentration, separation of biology pharmacy, food/drinks, and wine industry.
PES and PVDF, UF membranes are available upon request.
