Electrocoagulation (EC) process involves a detailed study discriminating the effect of pH, current density, the concentration of effluent and operating time. Continuous EC process was carried out with and without recirculation of DSW. Experiments were carried out to remove the color and COD of DSW by the electrocoagulation (EC). The wide range of operating conditions was implemented such as initial pH (3.1–8.7), current density (3.25–10.75A/cm2), initial COD concentration (5803 mg/L), and operating time (0–400 min). High- performance liquid chromatography (HPLC) analysis confirms the degradation of DSW. The pair of aluminum electrode removes chemical oxygen demand up to 94.88% and color 78.65%. Sludge analysis was carried out by using XRD to explore the result.
