MS® PVDF Pressurized UF Module

MS® hollow fiber PVDF UF module is made of high chemical-tolerant PVDF material with high clean-ability, low chemical consumption, high recovery, and a superior combination of mechanical properties and chemical resistance. And the PVDF pressurized Ultrafiltration elements widely apply in the Integrated Membrane System (IMS) for treating general water and industrial wastewater to protect downstream process of RO system.


  • Seawater RO pre-filtration  
  • Injection water treatment of Oil & Gas
  • Industrial sewage deeply treatment & reuse 
  • Municipal sewage treatment and reuse
  • Surface water and groundwater treatment 
  • Drinking water pre-filtration


  • Hydrophilicity modified PVDF, smoother, less fouling
  • Intercept particles, bacteria and viruses
  • High chemical resistance
  • High intensity for membrane silk lining
  • Simple process, reasonable design, easy to replace
  • Low operating pressure, energy saving, stable water quality
  • Good water quality: Turbidity≤0.1NTU, SDI≤3, SS<1mg/L
