Abstract

The Lake Kampeska Filtration Plant draws its drinking water supply from the Lake Kampeska as a part of the drinking water system for the city of Watertown, South Dakota. In this investigation, an ozonation pilot plant was used to determine the effect of ozonation on trihalomethane formation, odor, chlorine demand, and organics. Spectrophotometric characteristics were analyzed for surrogate parameter studies. Following a preliminary study based on trihalomethane reduction, ozone dosages of 0, 4, 8, and 12 mg/1 were applied to raw water at detention times of 10, 15, and 20 minutes. Analysis of variance showed that: (1) Ozonation of raw water reduced Total Trihalomethane formation, Chemical Oxygen Demand, and appeared to reduce odor. (2) Ozonation of raw water produced a higher chlorine demand. (3) Ozonation of raw water did not affect Total Organic Carbon concentration. Analysis of variance also showed that UV absorbance of unfiltered samples and color absorbance of uncentrifuged samples were suitable for estimating Total Trihalomethane concentration of the water.
