Treatment of Distillery Industrial Wastewater Using Ozone Assisted Fenton’s Process: Color and Chemical Oxygen Demand Removal with Electrical Energy per Order Evaluation

Ozonation is one of the most effective and efficient advanced oxidation processes (AOPs) has shown great potential in treatment industrial effluent wastewater. In present work, ozone-Fenton process for % COD color removal together with electrical energy per order (EE/O) determination distillery wastewater (DIW) was established. The developed by combining ozone (O3) Fenton (Fe2+/H2O2) process. (O3/Fe2+/H2O2) compared other such as O3, Fe2+, H2O2, O3/Fe2+, O3/H2O2, Fe2+/H2O2 EE/O efficiency DIW. at 100% chemical oxygen demand (COD) 96.875% were achieved a minimum 0.5315 kWh/m3 using O3/Fe2+/H2O2 operating optimum conditions. values obtained significantly higher than those processes. color, removal, its associated evaluated varying O3 inlet concentration, initial pH synergy effect reported. Our experimental findings suggest that could effectively treat
