Exploring HAA Formation Pathways During Chloramination

The use of chloramine for DBP control has received increasing attention in the U.S. water treatment industry since the first discovery of THM in drinking waters. Chloramination can almost completely suppress THM formation and reduce haloacetic acids concentration to 3-30 percent of the amounts formed during chlorination, making it a viable alternative to utilities for complying with the Stage 2 Disinfectants and Disinfection By-products Rule. This project investigated the routes of HAA formation during chloramination.
