One of the main problems associated with remediation of chlorinated solvent groundwater contamination is the presence of NAPLs in the source zone. NAPLs are often better treated through solvent extraction, surfactant washing, or vapor extraction than through bioremediation. Removal of NAPL through solvent extraction would likely leave a substantial residual of both the extraction solvent and th...

• PCE removed continuously using packed column and jet-mixer electro-scrubbers. Important chemical reactivity of PCE. No significant improvement with the addition cobalt mediators. Better performance jet-mixers In this work, removal perchloroethylene (PCE) continuous-operation electro-scrubbers is evaluated. Two types were made by combining a jet mixer or absorption single flow-cell. The absorb...
