ABSTRACT:
A process for the treatment of an aqueous media having contaminants therein, comprising adding hydrogen peroxide to the aqueous media; and exposing the aqueous media to a catalytic environment for a time long enough to form usable reactive intermediates and short enough to prevent scavenging of the usable reactive intermediates formed. Also provided is a reactor for achieving the process.
