Study on formation Characteristics of bromate in bromide water treatment by ozone

Abstract:

To control the formation of bromate in the treatment of drinking water with bromide by ozone,the influencing factors on bromate formation were studied in detail.Results of pilot test and pilot scale test show that,most of bromate are generated in the first 10 minutes of ozonation,;and when pH>8,the bromate formation is increased evidently;when pH<7,the bromate formation is limited under 10 μg/L.The existence of and NOM could inhibit the generation of bromate.When the concentration of NOM gets to 40 mg/L,the amount of bromate will be under 10 μg/L.
