THE REDUCTION OF BROMATE BY GRANULAR ACTIVATED CARBON

摘要

The removal of bromate, an inorganic disinfection by-product, by granular activated carbon (GAC) was investigated in this study. Bromate ion removal from water was observed in the presence of virgin and acid-washed outgassed (AWOG) GAC. In GAC filter with distilled-deionized water, bromate breakthrough occurred slowly whereas bromate breakthrough occurred very quickly in antural water due to the presence of natural organic matter (NOM) and other anions.
