Remediation of Contaminates Including Low Bioavailability Hydrocarbons

Number: 6,746,180
Year: 2004
Patent Status: Issued
Authors: Kukor, J.J., K. Nam

A method of treatment of a contaminated material contaminated with an organic compound. The method includes treating the contaminate with a chemical oxidation step and a bioremediation step. The chemical oxidation step includes treating the contaminate with the following: a transition metal in soluble form in combination with an isolated chelator of the transition metal, to form a transition metal:chelator complex; an oxidizing agent that provides a reactive free radical in the presence of the transition metal complex; and a buffering compound; the pH being maintained in a neutral range. The method of treatment further includes treating the contaminate with a microbial consortium including at least two species prior to or after the chemical oxidation step to enhance the remediation process.
