Decolorization of Industrial Waste Using Fenton Process and Photo Fenton

Industrial waste water decolorization has been done using the method of Fenton and Photo Fenton. The experiment was conducted in order to obtain the optimum process conditions for industrial waste treatment method with Fenton and Photo Fenton. Industrial waste used in this experiment waste of blue batik making process derived from Rara Djograng Batik Yogyakarta. Factors were studied in this research are the effect of the amount of catalyst FeSO4.7H2O, the amount of oxidant H2O2, and the time of oxidation in the Fenton and Photo Fenton. The optimum conditions of decolorization of blue batik waste by Fenton and Photo Fenton methods occurred in the number of FeSO4.7H2O 25 mg, the amount of H2O2 25 mL, contact time of 15 min at pH 3.0. In these conditions efficiency of decolorization reached 77.5% for the Fenton and 98.5% for the Photo Fenton process
