Product Overview

UFf225 capillary hollow fiber membrane is high polymer material, which will not have any phase change. Modified PVDF material, which is adopted on this product, has good permeable rate, good mechanical properties, good chemical resistance and pollution resistance. MWCO is 200K Dalton, membrane ID/OD is 0.8mm/1.3mm, filtering type is outside-in.


  • Drinking water treatment of tap water, surface water, well water and river water.
  • Pretreatment of RO.
  • Treatment, recycle and reuse of industrial waste water.
