Nanofiltration of pretreated Lake Houston water: Disinfection by-product speciation, relationships, and control

Influence of soluble microbial products (SMP) on wastewater disinfection byproducts: trihalomethanes and haloacetic acid species from the chlorination of SMP

“…Each water sample was dosed with a sodium hypochlorite solution (Clorox Bleach, 52.8 gL −1 ) at Cl 2 /TOC = 4. The specific quantity of chlorine dosage and TOC was shown in Table 2 25°C in the dark, and after that, each 15-mL sample of the chlorinated water was used to determine the species of THMs and HAAs, respectively (Chellam et al 2008;Xue et al 2008). The control experiment was conducted with model compounds and SMP in the SBR.…”

Modelling disinfection by-products formation in bromide-containing waters

“…It has been proved that chlorine reacts with NOM through both incorporation and oxidation reactions [11][12][13]. It has also been found that, in the presence of bromide, bromine competes with chlorine as consequence of the rapid oxidation of bromide to bromine [14][15][16][17][18][19]. DBP species containing bromine are formed as a result through the reaction pathway identical to that with chlorine [12,13].…”

Removal of viruses and disinfection by-products at two drinking water treatment plants in southern China

“…Each water sample was dosed with a sodium hypochlorite solution (Clorox Bleach, 52.8 g/L) at Cl 2 /TOC (total organic carbon) = 4. All samples were stored without headspace for 1 day at 25 o C in the dark and after which each 15 mL samples of the chlorinated water were used to determine the species of trihalomethanes (THMs) and haloacetic acids (HAAs) [20,21]. The free chlorine was standardized by the N,N-diethyl-p-phenylenediamine titrimetric method [22].…”
