🧪 EPA Stage 1/2 DBPR (Bromate Ion MCL 10 ug/L, Acid pH Suppression 6.5-7.0 Minimization)

Potable Water Bromate Control & Acid Feed Calculator

Model carcinogenic bromate ion (BrO3-) formation kinetics during ozonation of bromide-containing raw surface and groundwater: calculate sulfuric acid / carbon dioxide (CO2) chemical feed rates to suppress ozonation pH to 6.5 - 7.0 (or chlorine-ammonia pre-treatment), keeping finished water bromate strictly below the EPA Maximum Contaminant Level ($MCL = 10 ext{ }mu ext{g/L}$).
