Modeling the Formation and Propagation of 2,4,6-trichloroanisole, a Dominant Taste and Odor Compound, in Water Distribution Systems

2,4,6-trichloroanisole (2,4,6-TCA) formation is often reported as a cause of taste and odor (T&O) problems in water distribution systems (WDSs). The biosynthesis via microbial O-methylation 2,4,6-trichlorophenol (2,4,6-TCP) the dominant pathway pipes. This paper attempted to utilize data on process formulate deterministic kinetic models for explaining 2,4,6-TCA dynamics WDSs. pipe material’s critical role stimulating O-methyltransferases enzymatic activity regulating 2,4,6-TCP bioconversion was established. expressions formulated were later applied develop novel EPANET-MSX-based multi-species reactive-transport (MSRT) model. effects operating conditions temperature directing microbiological, chemical, organoleptic quality variations WDSs analyzed using MSRT model two benchmark systems. simulation results specified chlorine application’s implication maintaining levels within its perception limit (4 ng/L). In addition, sensitivity described, effect increase from 10 25 °C accelerating rate explained. Controlling source concentration by accepting appropriate treatment techniques recommended primary strategy T&O
