Hollow Fiber Membrane Technology

Prime water produces a super-efficient hollow fiber membrane, which has a high affinity for water and only needs low pressure to start the filtration process. Available in micro and ultra filtration versions, it delivers high flow rates at a low pressure gradient, with low energy consumption as an added benefit.

The Prime water capillary (hollow fiber) membranes have following properties:

  • Asymmetric micro porous structure.
  • 1 mm OD, with smooth inside surface.
  • Low pressure drops, ensuring high flow rates.
  • Very consistent pore sizes:
    • micro-filtration 0.2 µm (micron max)
    • ultra-filtration 0.025 µm (micron max)
  • High porosity (85 %).
  • Permanently hydrophilic
  • Pressure resistant up to 5 bar = 118 PSI.
  • Heat resistant up to 120°C (248°F) if applied in a polysulfone housing.
