Toray Pressurized UF/MF Membrane Modules

The material of Toray's Hollow Fiber (HF) Pressurized Ultrafiltration (UF) / Microfiltration (MF) modules is PVDF (Polyvinylidene fluoride). This best grade HF membrane material provides high mechanical strength and chemical resistance (oxidation, pH). Two HF membranes with different nominal pore size are available:

PVDF hollow fiber membrane HFU HFS
Nominal Pore Size or Nominal MWCO 150 kDa 0.02 micron meter
Recommended Applications Drinking Water Production * **
Industrial Water Treatment ** *
Seawater Desalination (for RO pretreatment) ** *
Wastewater Tertiary Treatment ** *
Special feature Low fouling layer -

*…Suitable / **…Recommended

The filtration mode is an Outside – in & Dead-End Filtration. This filtration method offers simple operating control and low energy consumption.

The possibility of the filtration of Ground Water, Surface Water, Sewage Secondary Effluent and Seawater allows a wide range of different applications:

  • Drinking Water Production
  • Tertiary Treatment of Sewage Water
  • RO Pretreatment in Seawater Desalination
  • Industrial Water Production
  • Reuse of Industrial Waste Water

Toray's Hollow Fiber Modules are available as microfiltration or ultrafiltration modules in a wide range of membrane area.
