In-situ remediation of contaminated ground water using the MAG*SEP{sup SM} technology
- Bradtec-US, Inc., Atlanta, GA (United States)
Argonne National Laboratory is leading a project for demonstration of in-situ remediation of contaminated ground water utilizing MAG*SEP{sup SM} technology developed by Bradtec. This technology is being considered for eventual application at sites involving groundwater contaminated with heavy metals and/or radionuclides, such as the Savannah River Site (SRS) and Berkeley Pit. The MAG*SEP{sup SM} technology uses specially coated magnetic particles to selectively adsorb contaminants from ground water. Particles are mixed with ground water, contaminants are adsorbed onto the particles, and the particles are removed by magnetic filtration. The technology can recover low levels of radioactive and/or inorganic hazardous contamination (in the ppm range), leaving nonradioactive/nonhazardous species essentially unaffected. The first phase of this project has involved the optimization of MAG*SEP{sup SM} process chemistry for a selected site at SRS. To date this work has identified a candidate adsorber material (the amino form of iminodicarboxylic acid) for selective removal of lead, cadmium, and mercury from this site`s ground water. Decontamination factors of 170, 270, and 235, respective, for each contaminant have been achieved. Further process chemistry optimization work for this adsorber material is planned. The project will eventually lead to an in-situ demonstration of the MAG*SEP{sup SM} technology, integrated with the EnviroWall{trademark} barrier technology developed by Barrier Member Containment Corporation (BMC).
