Mixed bed ion exchange is often used to polish Reverse Osmosis (RO) permeate in many industrial water systems. This process has been utilized for several years and it is well known that the management of the dissolved Carbon Dioxide (CO2) in the water is critical for an efficient operation.

CO2 typically accounts for the largest anion load in a DI system and it is normally handled using one of the following methods:

  • Conventional degasifying unit, such as a Forced Draft Tower
  • Liqui-Cel® Membrane Contactors
