In this study, COD and colour removal efficiencies of a textile industry wastewaters, which is located in Bursa City were investigated, using different advanced oxidation processes. Coagulation, Fenton, Fenton-like and ozonation processes were applied to the wastewater taken from the equalization tank of the treatment plant of the industry. The results show that, the best results for COD and colour removal were obtained using Fenton processes and ozonation. COD and colour removal efficiencies for Fenton process and ozonation were determined as %52 and %96, %51 and %98, respectively. Operating costs of various advanced oxidation processes were also determined in the study. Considering operation and investment costs, for COD and colour removal from textile industry effluent Fenton process was suitable.
