Today, the issue of sustainable development has become one of the most important global issues and has become the focus of attention and human attention in the economic, social, and environmental perspectives. Various human activities, as well as the development of industries and the expansion of urbanization with waste and wastewater, have contaminated soil. Different methods are available to clean up the soil about economic issues. One of them is the electro remediation method, which is often applied in low-permeability fine-grained soils and is successful as a greenhouse effect in reducing the toxicity of heavy metals and is a new and developing approach for organic pollutants. This paper will be presented the effective parameters, the strong points as well as limitations, to clarify the basic concepts in the electro remediation process. Conduct experiments with the three-dimensional arrangement of electrodes instead of the linear arrangement of electrodes could be more practical. Using geosynthetic electrodes to prevent corrosion of metallic electrodes, combining the electro remediation process with other designs and different operational modes, and overcome to the problem of reducing the electro-osmosis flow and reverse electro-osmosis flow with pH control are methods to enhance the rate of removal of pollutants from soils.
