Reverse Osmosis Membrane Applications
RO Membranes

We provide high quality Reverse Osmosis membranes from leading manufacturers. Elements are available for tapwater, brackish water and seawater applications.

 

 

 

 

APPLICATIONS

  • Low-pressure residential tapwater elements are used in single-element, point-of-use systems to treat pre-processed or municipal water. Elements produce from 10 to 100 gallons per day.
  • Commercial tapwater elements are used in single-element commercial and residential systems to treat pre-processed or municipal water. When used in systems producing up to 2 m3/hr (10 gpm), these are considered commercial applications.
  • Brackish water elements are used to treat water with salt concentrations between 50 and 10,000 mg/l. In commercial applications, these elements are used in multiple-element systems to treat pre-processed or municipal water.
  • Seawater elements are used for treatment of water with salt concentrations greater than 10,000 mg/l.
  • Ultra Low Pressure elements operate at a pressure of 80 psi. They are also the best choice to counter the negative effects of cold water on reverse osmosis production.
    Nano Filtration process used most often with surface water and fresh groundwater, with the purpose of softening and removal of organic matter.
