RO-MAN Reverse Osmosis Systems Mambranes

RO-MAN supplies Systems for Domestic drinking water, Public Aquariums, Universities & Hospitals, Industrial applications and Aquarium keepers.

Our staff are all trained in the Reverse Osmosis process - including comprehensive training in America by one of the leading specialists in the science of water purification. We have gone to these lengths because aftercare is so important to us. We will always endeavour to sort out any problems. To help with this we have a dedicated online helpdesk plus telephone support.

99% Of Membranes come for the US and are Calibrated in US Gallons
1 UK gallon = 1.200950 US gallons

Note:

  • Performance specifications based on,
  • 500 ppm tap water,
  • 65 psi (0.47 MPa) applied pressure,
  • 77°F (25°C) feed water temperature,
  • feed water pH 7
  • Recovery Element permeate flow may vary ± 15%

    Important Operating Information

    • Elements must be kept sealed and moist when in storage. Drying out will irreversibly damage the membranes.
    • Prevent elements from freezing, or being exposed to direct sunlight.
      Elements are shipped in sealed bags and contain a preservative solution of 1-2% (by weight) of sodium meta bisulphate (Food Grade).
    • Discard the permeate from the first hour of operation.
    • Permeate flow varies with feed water temperature. Divide the rated flow with the correction factor below to get the permeate flow at that temperature.
    • Membrane Elements for residential systems have a one year warranty from the date of shipment. Warranty is void for membrane elements fouled by suspended solids, precipitates or biological growth. Membrane warranty is also void if the membrane elements are improperly used, poorly maintained or improperly stored.
    • Warranty claims for membrane elements must be made as detailed in Membrane Warranty Claims Bulletin.
