- Abstract:
- Formation of bromate in source water of Q waterworks treated by ozone/potassium monopersulfate (O3/PMS) oxidation process was investigated, and the formation of bromate in different water containing bromide prepared by pure water, S school tap water, H spring water, source water of Q waterworks, and J reservoir water was compared and analyzed when treated by O3/PMS process. When source water of Q waterworks containing bromide was treated by O3/PMS, the inhibition of PMS on bromate formation showed an increasing trend with the n(PMS)/n(O3) (molar ratio) increasing in the range of 0-1.5, and the inhibition was the largest when n(PMS)/n(O3) was 1.5. When n(PMS)/n(O3) continued to increase, the inhibition of PMS on bromate formation was weakened. The effect of PMS on bromate formation was different when the different water quality containing bromide was treated by O3/PMS. When the pure water, H spring water and J reservoir water containing bromide were treated by O3/PMS, the combination of ozone and PMS promoted the formation of bromate. When O3/PMS was employed to treat S school tap water and source water of Q waterworks containing bromide, the combination of O3 and PMS inhibited the formation of bromate. The reason was mainly because of a series of reactions between organic matter in water and O3/PMS affected the formation of bromate.
