For many years chlorination has served as a barrier to protect human health from waterborne disease outbreaks. Chlorine is viewed as a near-universal oxidant and disinfectant, that provides a stable residual preventing microbial re-growth all the way through the consumer’s tap. Upon reaction with natural organic matter (NOM) however, it forms disinfection by-products (DBPs) many of which are potent human carcinogens and therefore have been of research interest since the 1970’s (Froese et al., 1999; Krasner et al., 2006, 1989; Richardson, 2003; Rook, 1976, 1974; Singer, 1994). The trihalomethanes (THMs) and haloacetic acids (HAAs) are the most prevalent (Krasner et …

This work examined the role of manganese oxide (MnOx) in the formation of disinfection byproducts (DBPs) in drinking water treatment. DBPs are of increasing concern as more is being learned about their carcinogenicity and genotoxicity. Studies were performed to determine the impact of MnOx and free chlorine (Cl2), used for dissolved manganese (Mn(II) removal, on the formation of these undesirable byproducts. Batch experiment results showed that the presence of MnOx did not significantly increase the haloacetic acid or trihalomethane concentrations. Rates of DBP formation were also similar in the absence and presence of Mn(II) …
