Abstract
A method of treating an organic contaminated material includes producing manganese oxide media in a first treatment system; and contacting the organic contaminated material with the manganese oxide media in a second treatment system. The manganese oxide media may be coated aggregate having a layer of manganese oxide. The manganese oxide media may be manganese oxide solids. The manganese oxide solids can be formed by removing at least a portion of the manganese oxide layer from the coated aggregate.
Claims15
A method of treating a contaminated material comprising organic contaminants, comprising:
- exposing aggregate to coal mine drainage containing manganese ions in a first treatment system such that the manganese ions adsorb and oxidize on the surface of the aggregate to form coated aggregate having a layer of manganese oxide;
- removing at least a portion of the coated aggregate from the first treatment system;
- placing at least a portion of the removed coated aggregate into a second treatment system;
- and
- exposing the coated aggregate in the second treatment system to a contaminated material comprising organic contaminants such that at least a portion of the organic contaminants are removed from the contaminated material.
A method of treating a contaminated material comprising organic contaminants, comprising:
- exposing aggregate to coal mine drainage containing manganese ions in a first treatment system such that the manganese ions adsorb and oxidize on the surface of the aggregate to form a coated aggregate having a manganese oxide coating layer;
- removing at least a portion of the manganese oxide coating layer from the coated aggregate to form manganese oxide solids;
- placing the manganese oxide solids into a second treatment system;
- and
- exposing the manganese oxide solids in the second treatment system to a contaminated material comprising organic contaminants such that at least a portion of the organic contaminants are removed from the contaminated material.

- removing at least a portion of the manganese oxide coating layer from the coated aggregate to form manganese oxide solids;
- placing the manganese oxide solids into a second treatment system;
- exposing the manganese oxide solids in the second treatment system to a contaminated material comprising organic contaminants such that at least a portion of the organic contaminants are removed from the contaminated material;
- and
- returning the aggregate having the at least a portion of the manganese oxide coating layer removed to form the manganese oxide solids to the first treatment system.
A method of treating a contaminated material comprising organic contaminants, comprising:
- exposing a contaminated material comprising organic contaminants to manganese oxide solids such that at least a portion of the organic contaminants is removed from the contaminated material, wherein the manganese oxide solids have been removed from aggregate exposed to coal mine drainage.
