Capture of ambient air CO from municipal wastewater mineralization by using an ion-exchange membrane.

The capture of ambient air CO from synthetic urban wastewater mineralization reaction was studied. An ion exchange membrane was used as sorbent, which adsorbs CO when dry and releases it when wet. The UV/HO degradation process was chosen to convert Total Organic Carbon (TOC) to carbon dioxide due to its advantages of convenience and fast kinetics over the conventional biological treatment that is usually used in urban wastewater treatment plants.
