Electrokinetic Remediation Setup in Field Applications

All the above-mentioned processes followed the fundamental electrokinetic techniques, but with some modifications in the process either by adding additional chemicals or in the configuration or construction of electrodes. From the cited literatures, an electrokinetic remediation setup essentially consists of the following 

Pollutants present in the soil are recovered from the electrode solutions and also, the chemicals to enhance the separation and transportation of pollutants are supplied to the electrode solutions. Therefore, a circulation system is important for the management of the electrode solution and to maintain the parameters like temperature and pH of the anolyte as well as the catholyte. A proper circulation control system enables complete mixing of electrode solutions and sample withdrawal also if necessary. It might also include a process piping to distribute any chemical amendments to electrode wells and to extract the contaminants from the electrode solutions (e.g. precipitation and ionic exchange). 

Apart from the above-mentioned systems, an electrokinetic setup might consist of other ancillary systems depending upon the site-specific characteristics, such as offgas extraction and treatment systems, by-product monitoring systems, and so on.
