Abstract |
A survey was conducted of chlorination practices at five power plants owned and operated by the Pacific Gas and Electric Company. Frequency and duration of chlorination varied significantly from plant to plant and was controlled analytically by the orthotolidine and/or amperometric methods. All the plants plan to change to using the amperometric method for future control purposes. In-plant studies were conducted during chlorination cycles to determine oxidant residuals at both the condenser inlets and at a point near the outfall. Both free and total oxidant residuals were measured amperometrically for most studies. The DPD-FAS method was included in later studies to gain a better understanding of the nature of the oxidant residual. These results indicated that most of the oxidant residual at the Hunters Point and Moss Landing power plants was bromine residual. Decay studies were conducted at the plant sites on the chlorinated cooling water collected at the outfall. The slowest decay was observed at the Contra Costa plant where the cooling water was the freshest. The most rapid decay was at the Hunters Point plant. The presence of sunlight increased the rate of decay at all locations. |
