Abstract
Cost-effective tailored earth materials and methods of making and using these tailored earth materials are disclosed. These tailored earth materials can be used to treat (filter) emergent contaminants, such as perchlorate, from water or brine. The sorbed contaminants on the spent tailored earth materials can be degraded after use by bioremediation.
Claims5
A method for bioremediation of a spent organoclay composition containing brines, at least one of an organoclay, at least one of a cationic surfactant and at least one of a sorbed contaminant comprising:
- providing at least one of a nutrient amendment;
- providing at least one of an electron donor source;
- and
- providing at least one of a contaminant degrading bacteria to stimulate biodegradation of the sorbed contaminant.
