CO2 Removal using Membranes
Preferred: CO2 Removal by GTM Gas Transfer Membranes like 3M’s Liqui-Cel™
Water, even pure water, contains dissolved CO2 gas and the ionic bicarbonate form HCO3-. Dissolved CO2 gas can be removed using GTM membranes; this is a closed clean system. Ionic HCO3- can be removed using RO if the pH is right. Understanding the pH of the RO feed, the RO permeate, and how this affects choice of CO2-removal strategy is important.
