The cost effective treatment of sugar industry wastewater is a challenging task. In the present work, an attempt
was made for the treatment of sugar industry wastewater using Electrocoagulation technique with Aluminum electrodes as
sacrificial anode in bipolar connection system. The effects of operating parameters such as pH, voltage and electrolysis
duration on the removal of Color and TDS were investigated. The optimum value for each operating variable was
experimentally determined. The optimum values of voltage, initial pH and electrolysis time were found to be 25V, 7.0 and 1
hours respectively. The experiments revealed that color and TDS in aqueous phase was effectively removed. The analysis of
the treated water showed that the maximum color and TDS removal efficiencies were 95% and 94% respectively at optimum
conditions. The effluent was very clear and its quality meets the discharge standard. Consequently, the Electrocoagulation
process can be considered as a reliable, safe and cost effective method for the treatment of sugar industry wastewater.
