Electrodialysis for metal removal and recovery: A review

Electrodialysis (ED) is a multipurpose technology that can be used for treating acidic effluents containing metal species. Its continuous operation capacity, scalability, and easy operation can solve most of the drawbacks of current technologies, and the direct reuse of concentrated metal streams can avoid the need for chemical addition and precipitation. Hence, ED emerges as a promising technology with a huge growth potential to concentrate, separate, and selectively recover metals from acidic effluents. This critical review aims to (I) review and discuss the types of ED processes and their state-of-the-art, (II) provide an insight on the most important parameters behind the ED technology, and (III) evaluate…
