Effects of Chlorine on Disinfection by-Products (DBPs) Formation in Synthetic Drinking Water

Abstract:

This study focused on the effect of chlorine on disinfection by-product (DBPs) formation. The concentration of DBPs and total residual chlorine were measured at the same time in synthetic drinking water. Chlorine demand and DBPs increased with chlorine dose and contact time. The descending DBPs formation potential rank was: TCM > DCAA > TCAA > TCNM > BDCM. Furthermore, a linear relation between the concentrations of DBPs (HAAs, THMs or TNMs) and chlorine demand was discovered, and the coefficients did not correlate with chlorine dose. Emerging N-DBPs such as HANs did not follow those disciplines because of their special structures. These results have instructive meanings to the further control of DBPs.
