Reverse Osmosis (RO / Deionization (DI))

Reverse Osmosis (RO) / DEIONIZATION (DI):

Reverse osmosis pre-treatment is a natural fit to pair with deionization.  RO system removes the majority of the ionic and organic impurities through a mechanical process.  RO water is added to the holding tank as required.  The content of the holding tank is recirculated through the DI Bottles to achieve high quality water.


The System is configured to match the application requirements:

  • Source water pre-treatment
  • Reverse Osmosis Element(s)
  • Ion Exchange Resin
  • Ultraviolet Lamp Assembly(s)
  • Particulate Filtration
  • Ultrafiltration
  • Degas
  • Inert storage tank (Nitrogen blanket)
  • Pressure Transducers
  • Flow Transducers
  • Water Quality Instruments
