Capacitative deionization based treatment and metal recovery from lead-acid battery recycling wastewater stream

Description :  

The objective of the investigator of this project is to revitalize the Louisiana lead-acid battery recycling industry through improved wastewater treatment and recycling. In collaboration with VerdeEn Recycling Solutions LLC, the investigator will address issues of treating hazardous metal-contaminated wastewater produced in the processing of lead-acid battery recycling. By using a capacitive deionization-based electrochemical method of wastewater treatment, the investigator may recover commercially valuable contaminants such as Copper, Antimony, Bismuth, Arsenic, Cadmium, and Tin. Capacitive deionization may be paired with graphene, carbon aerogel, and other carbon forms to remove the inorganic pollutants. In addition, high temperatures and varying flow rates combined with the regeneration phase of exhausted/saturated electrodes will be utilized to recover the metal ions from the wastewater. The expected results from this project may be applied to wastewater treatment in mining and oil and gas explorations.
