Paper Title
Electrochemical Treatment Of Dairy Effluents Using Aluminum Electrodes

Abstract— The dairy industry generates strong wastewater characterized by high BOD, COD, nutrients and inorganic content. Furthermore, the dairy industry is one of the largest sources of industrial effluents. Hence, the cost effective treatment of dairy effluents for environmental protection is a challenging task. The removal of pollutants from dairy was experimentally investigated using direct current electrocoagulation (EC). In this study, the effect of pH, electrolysis time (ET), applied voltages were examined. The COD and turbidity in the aqueous phase was effectively removed when aluminum electrodes were used. The optimum value of voltage, pH and ET were found to be 25V, 7.0 and 60 minutes respectively. The batch EC experimental results revealed that the overall COD, turbidity and phosphate removal efficiencies reached 94.7%, 96.7% and 89.4%. Thus, EC technology with aluminum electrodes in bipolar system could be an attractive alternative for the treatment of Dairy effluents.
