Electrocoagulation (EC) of undigested distillery spent wash with high color removal efficiency and COD was investigated using a set of aluminum and iron electrodes. The distillery spent wash was characterized for various parameters as per the standard method of analysis. The effect of operating variables such as voltage (V), electrode distance (cm), and electrolysis time (minute) on removal efficiency of color and chemical oxygen demand (COD) were studied. At a voltage of 20V, electrode distance of 3 cm and constant pH 7, the highest color removal of 87% and COD removal efficiency of 88 % were obtained with Fe-Fe and Al-Al electrodes respectively for 150 minutes of electrolysis time. The process proved the ability to effectively remove the COD and Color content which when high in industrial wastewater can lead to serious impacts on the environment.
