Full Description

To comply with the new regulations proposed by the Disinfectants/Disinfection By-Products (D/DBP) Rule, many utilities will be required to modify their treatment trains. The use of ozone as a pre-disinfectant/oxidant will be an option considered for DBP control by many utilities. Ozone can provide significant C*t credit and decrease the chlorine demand, reducing the required chlorine dose prior to distribution. However, ozonation generates byproducts that may be of health concern. Ozone DBPs include organic DBPs, such as aldehydes and ketoacids and the inorganic DBP bromate. The objective of this research was to systematically evaluate the impact of pH on the formation of bromate during ozonation of raw Ohio River water (filtered through a glass fiber filter) for a range of bromide concentrations at two ozone residuals.
