Redox-mediated electrodialysis multi-channel membrane module system for wastewater treatment and resource recycling

Abstract

Provided is a redox-mediated electrodialysis multi-channel membrane module system for wastewater treatment and resource recycling. Provided is a redox-mediated bipolar membrane electrodialysis (RBED) process, which combines a bipolar membrane electrodialysis (BPED) process with a redox flow desalination process, the present invention is driven at a low potential via a redox reaction with a low operating potential instead of the water-splitting reaction used in conventional electrodialysis. Consequently, the system exhibits superior energy efficiency. By utilizing this redox-mediated multi-channel membrane module system, high-efficiency desalination and resource recycling are possible for wastewater generated during secondary battery manufacturing and metal recovery processes. Furthermore, the energy consumed for desalination and resource recycling can be recovered, thereby providing high energy efficiency and cost competitiveness.
