TREATMENT OF SUGAR INDUSTRY WASTEWATER USING ELECTROCOAGULATION TECHNIQUE IN MONOPOLAR AND BIPOLAR ELECTRODE SYSTEMS

The space between all the electrodes was maintained 2cm in all the experiments. In each run the voltage was varied to a desired value of 10, 15, 20 and 25V. The volume of solution in each batch experiment is 1.00 L. Magnetic stirrer is used in all tests to ensure a homogenous solution in the batch reactor containing wastewater. About 2g/L of boric acid is added as electrolyte to the wastewater for each batch. The wastewater concentration is reduced to half the strength throughout the study to reduce the time.

And current consumption and to obtain better efficiency. Electrodes were washed with 15-20% HC1 followed by a detergent wash before experiment. The EC experiments were performed for 75mins and in each run samples were collected at every 15mins interval for necessary analysis. All the samples were allowed to settle for one hour before analysis.
