Advances in the industrial and urban sector has led to an increase in the release of contaminants into the environment. These activities can help in the growth of economy, but on the other hand, it leads to environmental problems and also has its effect on human health. To minimize these problems, remediation and reclamation is necessary. Remediation methods for soil/ sludge include physical, chemical and biological techniques. Biological methods such as phytoremediation and bioremediation are also adopted. A low cost treatment method known as electroremediation is an emerging technique in the remediation of marine sediments, soil contaminants, sludge and flyash. This technique uses low voltage direct current that is applied to the medium, which induces various physico-chemical reactions in the medium. This helps in the removal of oil hydrocarbons, and other pollutants. In this paper, the application of electroremediation in various environmental samples are discussed.
