The pharmaceutical industry requires a continuous source of purified water with a conductivity of < 1.3 µS/cm. Controlling and removing the dissolved CO2 from the water will allow the water to reach this conductivity level. Historically chemical dosing with NaOH was used to control the CO2. Today people are moving away from using chemicals because of their negative impact on the environment and the safety implications of people having to handle the chemicals.

Additionally, EDI and CDI have become a common technology for Ion Exchange in the pharmaceutical industry. These technologies operate more efficiently if the dissolved CO2 is first removed from the water. Excess CO2 in the water will load the EDI and require the installation of more EDI stacks than are necessary.

The pharmaceutical industry also requires high water quality without contamination. Liqui-Cel Membrane Contactors offer the ideal solution for gas control in the pharmaceutical industry. Systems with 3M Liqui-Cel are closed systems that do not introduce environmental contaminants into the water like an old Forced Draft Deaerator used to do. They also replace the need to use chemical injection.

Membrane Contactors also provide simultaneous O2 and CO2 removal which benefits any processes where oxygen can negatively impact the end product. Sometimes oxygen can affect the shelf life or product stability. The contactors offer an easy gas removal system that operates consistently 24 hours a day, 7 days a week.
