ABSTRACT:
A process is provided for treating aqueous streams contaminated with electron affinic contaminants. Accordingly, these contaminants are removed by producing a reactive intermediate that is generated in-situ and then reacting the reactive intermediate thus produced with the electron affinic contaminant. The reactive intermediate is produced in the aqueous stream by maintaining low levels of oxygen in the stream and by providing a reducing radical precursor, such as an alcohol, to the aqueous stream.
