How the Membrane System Works

The spiral membrane is constructed of one or more membrane envelopes wound around a perforated central tube. The permeate passes through the membrane into the envelope and spirals inward to the central tube for collection.

Operation Specifications

  • Feed water temperature = 95º F Max.
  • Feed water pressure = 40 to 80 psi
  • Turbidity should be removed
  • Maximum operating pressure: 1000 psi
  • Iron tolerance: 0.05 ppm Max.
  • Feed water TDS: 42,000 ppm, or higher as an option
  • pH range: 3-11
  • Chlorine and other oxidants should be removed
  • No bacteriological or organic content
  • Membrane rejection: 95-99%
