Abstract
AbstractThis study was carried out to investigate the effect of the electrocoagulation reactor design parameters in the removal of zinc from water. In order to optimize experimental electrocoagulation reactor parameters such as inter electrode distance (die), electrode connection mode, surface-area-to-volume ratio (S/V), and the initial temperature of the solution (T), many electrocoagulation tests were performed using aluminum electrodes. The obtained experimental results showed that optimal zinc removal was achieved with a distance between electrodes of 0.5 cm, a bipolar connection mode, the surface-area-to-volume ratio (S/V) of 13.6 m−1, and for an initial temperature (T) of 50°C. The application of these results on the treatment of a sulfuric acid and superphosphate manufacturing industry wastewater made it possible to achieve a total zinc removal in five minutes of electrolysis time.
