| Abstract Scope |
Bipolar-assisted electrodialysis (BPED) is a membrane-based separation technique widely used for treating wastewater. One of its major advantages is the ability to produce three valuable products: a base, an acid, and desalinated water. This study explores the use of BPED to treat wastewater generated during battery recycling, which contains lithium and complex chemical compositions. The efficiency of lithium recovery is a key metric of the process. Various parameters, including the initial concentration of acid and base compartments, stack voltage, volume ratio, and processing time, were examined and optimized. The purity of the recovered lithium product, lithium hydroxide (LiOH), was evaluated to meet battery-grade standards. |
