Corrosion control by use of limestone contactors was evaluated both in the laboratory and at a field installation. As water is transported through a packed bed of limestone, calcium carbonate dissolves and the pH, calcium ion concentration, and alkalinity increase. A mathematical model was derived for use in contactor design. The …
