The OWUF（External Ultrafiltration Membrane Module）, breaking 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, is featured with higher seawage interception and larger filtration area. Thus, the system is ensured to run stably for a long term. The product is one of the significant achievements in Major Science and Technology Program for Water Pollution Control and Treatment during “the 12th Five-Year Plan”, and it has been awarded as the New Technology and New Product in Zhongguancun, the Beijing New Techn ology and New Product，etc.
Excellent effluent quality: Narrow membrane pore size distribution, high filtration precision, more than 6log of bacterial retention rate, more than 41og of virus retention rate;
Strong fouling resistance: Due to wide spacer structure, pulsating operation and special homogenized disk structure, secondary water and air distribution is realized and fouling is effectively controlled;
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”patent technology for membrane production, the 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.
