Abstract

The patent is aimed at treating industrial wastewaters, containing high concentrations of ammonia, by using a bromide enhanced ozonation process that avoids the generation of nitrate. The treatment is based on the optimization of an already-know process that uses the reaction between ozone and bromide to generate hypobromous acid (HOBr) and, through this, gaseous nitrogen.
