AWWA WQTC55012

The concern over trihalomethanes in drinking water has led researchers to explore other disinfection options other than free chlorine. One disinfectant that is showing promise is chlorine dioxide, a powerful oxidant that has a high disinfection capacity and produces significantly less trihalomethanes. However, the impacts of chlorine dioxide on corrosion in water distribution systems has not been widely reported. The objective of this study is to study the impacts of free chlorine, monochloramine, chlorine dioxide and chlorite on internal corrosion and water quality in a pilot-scale pipe loop system. Results from this study have shown that relative to the free chlorine and monochloramine pipe loops, chlorine dioxide lower corrosion rates and lower concentration of total iron in the effluent. It was therefore concluded that, in addition to being a strong disinfectant, chlorine dioxide could also be used to mitigate red water problems in distribution systems.
