Abstract
A process for the treatment of an aqueous media having contaminants therein, including adding hydrogen peroxide to the aqueous media, exposing the aqueous media to a catalytic environment, removing the aqueous media from the catalytic environment prior to the aqueous media having a five minute residence time within the catalytic environment, thereafter adding ozone to the aqueous media, and allowing the ozone and aqueous media to interact outside of the presence of the catalytic environment.
