Use KMn04 to control bromate formation during drinking water ozonation:influencing factors
This formation of bromate during ozonation of polluted source water has long caused great concerns.This paper used KMnO4 to control the bromate formation during water ozonation.KMnO4 was added 10 min prior ozone to oxidize the organic pollutants.The initial Brconcentration was 1000 μg/L.The results showed that the bromate formation efficiency was low (<5%) during KMnO4-ozone oxidation.Among KMnO4 dose,ozone dose,and source water TOC,the single most important factor for bromate formation was the ozone dose.When the ozone dose was 3 mg/L or higher,the bromate concentration exceeded the national standard no matter what level of KMnO4 was used.The organic pollution level had little influence on the bromnate formation.
