For years, many industries have used Membrane Contactors for carbon dioxide removal from water. Systems utilizing RO and Deionization technologies need to reduce the amount of carbon dioxide in the water. High inlet conductivity levels into an RO or DI Tanks will reduce the resistivity of the outlet water.
A common cause of the high conductivity is dissolved carbon dioxide. Membrane contactors provide a clean, maintenance free method to remove carbon dioxide from water without any chemical pH adjustment. RO systems will produce higher quality water if the CO2 has been removed upstream, thus extending the life of Deionization Tanks.
Smith Engineering prefers Liqui-Cel® Membrane Contactors for their operational efficiency, cost/value, and ease of installation. There is a cost saving and environmental benefit when using Liqui-Cel® Contactors instead of chemicals to remove carbon dioxide from water.
The contactors are small and compact and offer a preferred alternative to chemical injection and forced draft de gasifiers. Contact Smith Engineering to discuss how CO2 removal might make sense for your process.
