Generic RO Systems

How permeate pump worksReverse osmosis systems offer a more advanced treatment process than carbon filtration only or entry level pour-through pitchers. At the heart of the system is a reverse osmosis membrane which removes impurities as small as an atom! Additionally, drinking water passes through a series RO filters of sediment and carbon, eliminating any unwanted tastes and odors, giving your water a polished fresh taste. Fresh Water Systems offers a great range of reverse osmosis replacement filters and RO systems for your home. Contact us today if you have any questions about replacement RO filters or systems.

About the Reverse Osmosis Membrane:

Thin Film Composite Membrane vs. Cellulose Tri-Acetate Membrane
RO TFC membranes are much more effective than CTA reverse osmosis membranes due to their superior performance on water supplies with high pH, TDS, and hardness. Additional benefits of TFC membranes include:

  • Greater Reduction of Contaminants
  • Longer Membrane Life
  • Better for Low Pressure Applications
  • More Water Production

  • Upgrading Reverse Osmosis Membranes to Higher Gallon Output:
    If purchasing a higher capacity membrane for an RO system, you must also select a matching flow control. This will insure adequate flushing and the long term functioning of the reverse osmosis system.

    Reverse Osmosis Membrane Retrofitting CTA with TFC:
    TFC Membranes require non-chlorinated water. All municipal water supplies use chlorine or chloramine as a disinfectant. If retrofitting a system that originally used a CTA RO membrane, make sure to replace the sediment prefilter with a Carbon Block RO Prefilter to remove the chlorine. If the RO system has two prefilter housings, install the carbon block RO prefilter in the second housing after the first sediment filter. On non-chlorinated water supplies, no change to the prefilter is necessary. If you need further assistance finding the correct reverse osmosis prefilters let us know.
