OWUF (External Ultrafiltration Membrane Module)

The OWUF (External Ultrafiltration Membrane Module), is featured with higher sewage interception and larger filteration area. Due to the patented OWUF membrine module broaken through the design of polyvinylidene fluoride (PVDF) ultrafiltration super-hydrophilic modification and new detachable structure and eliminating membrane fouling in the application process of ultrafiltration membrane, it is ensured to run stably for a long term. It has been successfully applied to  large membrane seawater desalination project of (100,000t/d).


  • Excellent effluent quality: Narrow membrane pore size distribution, high filtration precision, more than 6 log of bacterial retention rate, more than 4 log of virus retention rate;

  • Strong fouling resistance: Due to wide spacer structure, pulsating operation, special homogenized disk structure, secondary water and air distribution is realized and fouling is effectively controlled;

  • Strong corrosion resistance: Membrane produced with PVDF material is more resistant to seawater corrosion;

  • Low maintenance cost: Due to detachable structure, components can be recycled and the cost is saved;

  • Long service life: Due to new blending formulation and“3H” atent technology for membrane production, the service life is more than 5 years.



Note: *Design flux is determined based on the water temperature and water quality conditions.


Note: The pouring sealant material is epoxy resin; the siphon material is UPVC.
