Results of examination of the formation and control of disinfection by-products (DBPs), specifically total trihalomethanes (TTHMs) and total haloacetic acids (HAAs) in water treatment, are described in this article. Systems analysis models for TTHMs and HAAs for drinking water treatment plants using 28 surface water sources in Ontario are developed. Statistically, significant predictive regression models for TTHMs from dissolved organic carbon (DOC), chlorination and temperature (r2=0.72) and HAAs from DOC, chlorination and pH (r2=0.72) are demonstrated. These models are used to consider options to decrease DBP formation by shifting from pre-chlorination to post-chlorination, demonstrating that the potential may exist by applying more of the chlorine at a later point in the treatment sequence. This type of shift may reduce TTHMs by up to 63% and HAAs by up to 39% for the conditions being experienced at Ontario surface water treatment plants. |
