Aeration is often used to reduce the carbon dioxide liberated by a treatment process. For example, ,acid, may be fed to the effluent of sodium zeolite softeners for boiler alkalinity control. Carbon dioxide is produced as a result of the ,acid, treatment, and aeration is employed to rid the water of this corrosive gas.

Stripping sour water: the effect of heat stable salts

Caustic injection on a lower ,tray, generally works better than injection directly into the SWS feed itself because the H2S concentration is already small on lower trays. However, ,pH, is extremely responsive to caustic addition, so the measuring and control elements should be as close together in time as possible if rather large fluctuations in ,pH, are to be avoided.
