Abstract:

Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate ion was formed when water containing bromide ion was ozonated. It was concluded that bromate ion was chemically reduced to bromide ion by the granular activated carbon. Also, reverse osmosis nanofiltration rejected bromate and bromide ions an average of 89% and 84%, respectively, whereas hyperfiltration rejected bromate and bromide ions an average of 97% and 89% respectively.
