Asaithambi, Esayas Alemayehu, Baharak Sajjadi, Abdul Raman Abdul Aziz Comparison of UV, H 2 O 2 , Fe 2+ , UV/H 2 O 2 , UV/Fe 2+ , Fe 2+ /H 2 O 2 and UV/Fe 2+ /H 2 O 2 processes for the removal of percentage color, COD and electrical energy per order from the effluent distillery industry. The results showed that, UV/Fe 2+ /H 2 O 2 process yield higher percentage color and COD removal with low electrical energy per order than UV, UV/H 2 O 2 , UV/Fe 2+ process. To obtain the UV/Fe 2+ /H 2 O 2 process performance by operating various parameters on the percentage color and COD removal using response surface methodology. A Regression quadratic model describing the percentage color and COD removal efficiency of UV/Fe 2+ /H 2 O 2 process were developed and validate by analysis of variance. Experimental results showed that, UV/Fe 2+ /H 2 O 2 process can effectively reduced 96.50% of color and 84.40% of COD removal of the distillery industry wastewater under the optimum conditions such as Fe 2+ –1.50 mM, H 2 O 2 –200 mM, COD–1500ppm and pH–3.2, respectively. Result concluded that, UV/Fe 2+ /H 2 O 2 process can be used effectively for the treatment of real industrial effluent. Graphical abstract
