Electrochemical treatment of actual sugar industry wastewater using aluminum electrode Sahu, O. P.; Gupta, V.; Chaudhari, P. K. & Srivastava, V. C. Abstract In the present study, electrochemical (EC) treatment of sugar industry wastewater (SIWW) was investigated using aluminum electrode. Effect of various parameters such as pH, current density (CD), electrode gap and electrolysis time was evaluated for chemical oxygen demand (COD) and color reduction. Energy requirement and electrode loss were found to increase with an increase in pH. Kinetics studies showed that the COD reduction rate was second order with respect to organic materials (COD) and 0.591 order with respect to CD. Filtration of treated slurry was found to be best near the neutral pH, while settling was best at pH 10. Operating cost of the treatment has been calculated. Results demonstrate that EC can be applied to reduce pollution load of SIWW. Keywords COD removal; Color removal; Current density; Filtration; Settling
