Abstract

A method and system treat contaminated water. In one embodiment, the method comprises treating contaminated water by introducing a methylmorpholine-N-oxide solution to a vessel. The vessel contains the contaminated water and iron oxide. The contaminated water comprises contaminants. In addition, the methylmorpholine-N-oxide solution comprises methylmorpholine-N-oxide and water. The method further comprises contacting the methylmorpholine-N-oxide solution with the contaminated water. In addition, the method comprises treating the contaminated water by allowing the methylmorpholine-N-oxide to react with the contaminants in the presence of the iron oxide.
