Full Description

Draft drinking water regulations in the US will specify a maximum contaminant level (MCL) of 10 ug/L for bromate ion (BrO3-), an ozonation byproduct produced during drinking water treatment. Several different options to remove BrO3- after its formation, applicable to conventional drinking water treatment plants contemplating the use of ozone at various points of application, have been evaluated: ferrous iron reduction (Fe2+), activated carbon surface reduction (GAC), and ultraviolet irradiation (UV). In all processes, chemical analysis of the treated water showed the formation of bromide ion (Br-) indicating that chemical reduction of BrO3- is the significant mechanism; adsorption of BrO3- onto the surface of iron floc is insignificant. BrO3- removal is activated carbon specific, and not all carbons have shown the ability to reduce BrO3- to Br-.
