ABSTRACT Response surface methodology (RSM) with central composite design (CCD) was used to monitor and optimize species-specific interaction of trihalomethane (THM) precursors in a scaled-up distribution network (DN). Independent variables such as applied chlorine (Cl2), contact time (t), humic acid (HA) and bromide ions (Br−) were analyzed using full factorial CCD. Analysis of variance revealed a good agreement between experimental data and proposed a two-factor interaction model (p = .04, R2…

Since the surface water is one of the main potable water resources, the usage of chlorine as a disinfectant has increased. Consequently the production rate of disinfection by-products (DBPs) such as
Factors Affecting the Formation of Organic By-Products During Water Chlorination: A Bench-Scale Study
The formation of chlorination by-products (CBPs) was investigated through bench-scale chlorination experiments with river water. The compounds selected for analysis belonged to the groups of
Laboratory-scale chlorination to estimate the levels of halogenated DBPs in full-scale distribution systems
TLDR
Results of this research suggest that the use of experimental data to predict halogenated DBP levels in full-scale distribution systems – for operational, regulatory and epidemiological purposes – must be done with caution.
[Effects of bromide and ferric ions on formation of tri-halomethanes during disinfection of drinking water by chlorine].
TLDR
The results showed that bromide in this reaction system not only contributed to the increase of brominated species, but also the total tri-halomethanes, which can result in the biggest challenge on carcinogenicity risk in alkalescent environment.
