The Use of Peracetic Acid as a “Pre-Oxidant” for Drinking Water Applications

Chlorination as a technology for drinking water disinfection has significantly reduced the incidence of human disease and is one of the most significant contributions to the improvement of human health over the past century. Chlorine’s ability to provide a stable residual concentration makes it suitable as a drinking water disinfectant at the point of use. However, natural organic matter in the raw water being treated and disinfected at the drinking water treatment plant may interact with the residual chlorine to form compounds classified as disinfection by-products (DBPs).
