The Control of Brominated By-products and the Removal of Organic Pollutants during the Ozone/Hydrogen Peroxide Treatment of Secondary Effluent

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.

Keywords:
