AWWA ACE92128

The objective of this study was to investigate the reactions of specific OBPs with chlorine and chloramines through evaluation of the kinetics and stoichiometry of chlorine demand and total organic halide (TOX) formation as a function of pH. Several OBPs routinely found in practice were selected for study due to their simplicity and minor variations in chemical structure. All of the compounds studied in this work have a carbonyl (C=O) functionality, and thus the types of chemical reactions may be similar. The nature of the chemical substituent (e.g., methyl group, hydrogen, etc.) adjacent or alpha to the carbonyl carbon has a strong bearing on the reactivity of the compound. Simple compounds were chosen from three classes of carbonyl compounds, aldehydes, keto-aldehydes, and keto-acids, in order to study the relationships between structural characteristics (e.g., functional groups and alpha substituents) and reactivity towards secondary disinfectants (kinetics, stoichiometry, chlorinated byproducts).
