Abstract

An investigation is given to the bromate formation of catalytic ozonation in treating drinking water. It is shown that the c × t value of ozone depletion stage plays a more important role in BrO₃^- formation. Catalyst addition not only reduces the residual ozone content by 60.0%-77.4% but also extends the ozone ID stage time from 4.3 min to 6.8 min, which makes the ozone c × t value shorter. A full-scale study indicates a very effective strength and performance of catalytic ozonation in controlling BrO₃^- formation and it is able to suppress BrO₃^- formation potential by 51.7% on average.
