Electro-bioremediation: An Advanced Remediation Technology for the Treatment and Management of Contaminated Soil
- 372 Downloads
Abstract
The world’s soil is being contaminated by various influences such as urbanization and industrial activities, for instance, the uncontrolled discharge of industrial wastewater. This chapter is mainly focused on electrokinetic (EK) techniques for remediation of soil polluted by the textile industry. Electrokinetic technology is employed for the removal of heavy metals and organics by applied direct electric current, which may induce the movement of pollutants from the matrix. However, so far only limited studies are available about the treatment of textile industry-contaminated soil. The present article describes approaches that can be utilized for the treatment of soils polluted by organic or inorganic compounds. Therefore, the EK removal of heavy metals, inorganic ions, and various textile dye contaminants is summarized, and the state-of-the-art is reviewed along with future trends for EK remediation of contaminated soil.
