Abstract :A hybrid wastewater treatment method was used to improve the quality of the treated wastewater for possible reuses. Real textile wastewater was subjected to electrocoagulation and Fenton like oxidation sequentially. In the Fenton like oxidation process the performances of BiFeO3/RHAC and BiNiO3/RHAC insert ignore into journalissuearticles values(RHAC: Rice husk based activated carbon); catalysts were compared. BiNiO3/RHAC was determined to be more effective in total organic carbon removal. A parametric study was carried out in the presence of the selected BiNiO3/RHAC catalyst to investigate the effect of the catalyst loading, pH and the oxidant dosage on total organic carbon removal. The most suitable reaction conditions were determined as 1.5 g/L of catalyst loading, pH 7, and 2 mM initial hydrogen peroxide concentration. 17% and 15.7% total organic removal efficiencies were achieved in electrocoagulation and Fenton like oxidation processes, respectively, whereas the cumulative removal efficiency was 32.7%.
