97-11: A New Treatment for Calcium Carbonate Control in Alkaline Conditions GeneralThe increasing costs associated with makeup and discharge water, as well as safety issues associated with the use of acid for pH control demand that cooling towers be operated at higher cycles of concentration without acid feed. Under these conditions, high calcium ion concentrations and high alkalinity at high pH makes control of calcium carbonate extremely critical. The paper presents laboratory data and history in which the effectiveness of a new
