Once-through cooling systems, especially cooling lakes, generally operate at low calcium carbonate supersaturation and are easy to chemically treat for scale/deposit control. However, due to the large volume of water that must be cost effectively treated, chemical treatment optimization becomes extremely important. This paper discusses a laboratory procedure for optimization, a computer program for predicting optimum dose, and field verification using a test loop heat exchanger at a power plant. Due to short residence time and low supersaturation of the water, a constant composition technique was used in the laboratory for optimizing chemical treatment and the results were found, generally, in good agreement with the field study.
