Abstract
This study aims to establish appropriate conditions to control the formation of bromate ion and brominated organic compounds during the O3/H2O2 treatment of the secondary effluents of sewage. When the H2O2/O3 mole ratio of injection was above 0.5 and the dissolved ozone concentration was below 0.1 mg/L, bromate ion formation was controlled, and treatment purposes such as the reduction of estrogenic activity or organic matter were completed. The formation of TOBr and individual brominated organic compounds during O3/H2O2 treatment was also completely controlled.
