WebJan 1, 1998 · This paper applies second-order kinetics to describe both of these relationships, using data collected from a recent collaborative study between the EPA and the American Water Works Association Research Foundation. It demonstrates that TTHM formation can be characterized as a function of chlorine demand.

Webimpact of changing treatment approaches on TTHM formation (Harrington et al., 1992)10. The output from that model was used to support the development of the DBP regulations, and the equations and models were further updated in the late 1990s. The most recent predictive equations used in a regulatory context have been reviewed and published by WebOct 1, 2002 · The authors provide a simple mechanistic model to predict total trihalomethane (TTHM) and the sum of nine haloacetic acids (HAA9) formation based on chlorine demand. To evaluate this modeling approach, eight Missouri surface waters (raw and alum-treated) were used in DBP formation and chlorine decay kinetic studies.
WebAug 29, 2024 · Trihalomethanes (THMs) are prevalent disinfection by-products. High THM formation is usually associated with natural organic matter with high molecular weight and aromatic characteristics, which is efficiently removed by nanofiltration (NF).
