Influence of catalytic ozonation process on suppressing bromate formation potential in drinking water treatment
2008
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 BrO~-_3 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 BrO~-_3 formation and it is able to suppress BrO~-_3 formation potential by 51.7% on average.
