Full Description

One of the greatest concerns in drinking water treatment is the formation of brominated disinfection byproducts (DBPs) through the addition of chlorine, chloramines, or ozone to waters containing bromide and natural organic matter (NOM). The brominated DBPs that occur in the greatest concentrations thought to have the greatest risk are the trihalomethanes (THMs), haloacetic acids (HAAs), and bromate, although the formation of brominated haloketones and haloacetonitryles are also known to occur. It has been shown that the brominated THMs pose a significant cancer risk when ingested while trichloromethane (chloroform) does not (US Environmental Protection Agency 1997). In a recently published paper, a bench-top process was presented which removed bromide from high bromide/high THM formation potential (THMFP) California State Project water (Kimbrough reaction rates; changes in disinfection byproduct formation procedure (DBPFP) through the reactor; oxidation and volatilization of bromide in the reactor; post-reactor volatilization; and, post-reactor volatilization in the air stripper. The five analytical techniques that were used in this study are listed. Includes 5 references, figures.
