In this study, the performance of electrocoagulation (EC) for the removal of mixed heavy metals such as chromium, copper, lead, nickel, and zinc from electroplating industrial wastewater was investigated. The objective was to determine the optimal operational parameters affecting the EC process, including electrode material, initial pH, inter-electrode distance, electrode size, and applied voltage. An experimental methodology was employed, where varying conditions were tested to assess their impact on metal removal efficiency. The results indicated that a pH of 8 yielded the best removal rates, with the Fe-Fe electrode pair, a 1-cm inter-electrode distance, and an electrode surface area of 40 cm² operating at an applied voltage of 8 V resulting in maximum removal efficiencies of 96.2% for Cr, 96.4% for Ni, 99.9% for Zn, 98% for Cu, and 99.5% for Pb within 30 minutes of reaction time. Moreover, the energy consumption under these optimal conditions was calculated to be 51.40 kWh/m³. These findings demonstrate the effectiveness of electrocoagulation as a viable method for the removal of heavy metals from electroplating effluents.
