Description:
This SBIR Phase I project will demonstrate the feasibility of an innovative electrochemical process for high efficiency simultaneous recovery of mixed heavy metals from contaminated groundwater. Electrochemical recovery of metals from wastewater is a promising approach for metal recycle. However, the conventional electro-chemical method is not efficient to treat dilute wastewater. Additionally, when the wastewater contains two or more heavy metals, the metal with the more negative reduction potential is difficult to recover. For example, when wastewater containing the mixture of copper and lead is treated, lead can be removed efficiently only after the copper concentration is much lower than the lead concentration. Faraday Technology's innovative approach will demonstrate an efficient, simultaneous electrochemical/ion-exchange process.Supplemental Keywords:
