Abstract: To predict how much bromate is being formed during a water treatment process a predictive model is needed that is based on the general unit processes and water quality characteristics of drinking water treatment. With a bromate prediction model, water treatment plant operators would have the ability to estimate the amount of bromate that would form in the resulting drinking water and alter their operating conditions to reduce the formation. The formation of bromate is a very practical problem that is occurring at all operating plants that use ozone as a disinfection agent. The objectives of this project include but are not limited to the following: 1. Determine seasonal variations in the bromide concentration and bromate formation in relation to water quality characteristics. 2. Provide a relationship between operational conditions and bromate formation. 3. Develop a model that predicts bromate formation based on water quality characteristics. Overall, the main goal of the research project is to gain knowledge pertaining to water quality parameters that influence bromate formation, and provide this information to water plant managers/operators so they can operate their plant accordingly and effectively reduce the harmful disinfection byproduct, bromate.
