Toxic metals are increasing contaminants due to modern day municipal wastewater/sludge,farming and mining practices.Water on earth is finite resource and facing shortages due to wide spread pollution.At shallow depths,in-situ electrokinetic processes like electrochemical oxidation,electro-osmosis and electro-ionization can effectively remediate these toxic metals threats.There are 7 practical scenarios on the electrokinetic treatment of heavy metals: Ex-Situ Sludge Dewatering and Metals Removal In-Situ Farmland Toxic Metals Treatment In-Situ Acid Mine Drainage Remediation In-Situ Mine Tailings Dam Remediation Ex-Situ River Water Remediation In-Situ Groundwater Remediation Farmland Toxic Metals Remediation in China(special cleanup requirements)
