The chrome plating industry generates wastewater containing toxic chromium(VI) ions, necessitating effective treatment methods for chromium recovery and water conservation. This study's objective was to explore an electrochemical ion exchange (EIX) method that combines ion exchange and electrodialysis processes for removing and concentrating chromium ions from rinsewater. Implementing batch recirculation operations at a voltage of 12.5 V allowed the researchers to achieve an impressive maximum chromium removal rate of 98.82%. The results indicate that increasing the operational voltage accelerates chromium removal while simultaneously decreasing the necessary treatment time. Moreover, specific energy consumption metrics were calculated to understand the efficiency of the treatment process better. This study presents a promising approach for recycling treated chromium-laden rinsewater, allowing it to be reused in plating operations, thus contributing to waste reduction and environmental sustainability in metal finishing industries. Future work will focus on optimizing the EIX process further and its scalability for industrial applications.
