Tiered approach for the assessment of bromate control strategies based on the results of this work. In the blue area, the focus should primarily be on removing bromide from entering the ozonation process and on minimizing bromate formation through optimizing ozone dissolution, adding specific chemicals that sequester bromide, and/or disrupting bromate formation reactions. In the green area, if these solutions are not viable, then the question of whether ozone should be used should be assessed. The brown area shows options and limitations of downstream treatment for bromate abatement.
