Abstract:

Due to exhaustion of fossil fuels and water pollution caused by discharge of industrial wastewater, sustainable energy production and zero effluent discharge are now becoming the two main global environmental issues to be faced by the humanity. This study investigates the electrolysis of rice mill wastewater in the presence of sulfuric acid to produce hydrogen. High purity hydrogen gas (>99%) was produced by decomposition of organic compounds by the application of electricity. Effect of acid concentration was investigated and the results illustrate that the increase in acid concentration improves the rate of hydrogen production with reasonable COD reduction. Current efficiency of the electrolysis was found to be greater than 90%. Cumulative hydrogen production of 700ml per hour was obtained for 5V. Maximum energy efficiency (26%) of the process was achieved at acid concentration of 3wt% and applied voltage 4V. Platinum coated titanium electrodes used for electrolysis have not been etched during the operation.
