Practical Aspects of In-Situ Electrokinetic Extraction

摘要: Electrokinetic extraction in an emerging technology that can be used to remove contaminants from heterogeneous fine-grained soils situ. Contaminants the subsurface are removed by application of a direct-current electric field across contaminated soil. The primary contaminant transport and removal mechanisms electroosmotic advection ionic migration. However, there many complex physicochemical reactions occurring simultaneously during process may enhance or retard cleanup process. Nonetheless, viability has been established results obtained bench-scale large-scale laboratory pilot-scale experiments performed on various soils. This paper will review fundamental concepts discuss some important practical aspects design criteria for implementations. An example cost analysis is also presented demonstrate use equations illustrate cost-effectiveness technology.
