UPDATE ON ELECTROKINETIC BASED SOIL DESALINIZATION FIELD TEST
Athmer, C. and D. Andersen.
2018 IPEC: 25th International Petroleum Environmental Conference, October 30 - November 1, 2018, Denver, Colorado. 29 slides, 2018

Electrokinetics (EK) technology can provide an approach to remediation of brine-contaminated soils via the application of DC electric fields in the soil mass to induce electromigration of the soluble ions. During desalinization, the chloride ions migrate toward anode wells and sodium ions migrate toward cathode wells, where they are removed. A full-scale EK desalinization process, installed in a wetlands area in North Dakota in May 2016, has been operated for 3 summer periods and shut down during the winter months. The system contains a grid of 93 electrode wells, a DC rectifier, and simple peristaltic fluid management system. The electrode wells were installed using a Geoprobe® unit. A trailer containing the rectifier and remote data monitoring equipment was placed adjacent to the site. This presentation describes EK system installation at the North Dakota site, operations and maintenance, and results to date.
