The control of bromate formation in ozonation of bromide-containing water

Abstract

Bromate formation under different conditions of ozone-based treatment for bromide-containing water was investigated. The paper not only presented common influencing factors such as temperature, pH, addition of ammonia or hydrogen peroxide, but also explored the effect of utilization of metallic compounds containing magnesium oxide, titanium oxide, potassium permanganate, and copper sulfate. The results showed that bromate formation could be significantly inhibited by increasing acidity, addition of ammonia or permanganate. And cooling the ozonation system is an alternative to control bromate formation.
