Homogeneous and Heterogeneous Catalytic Ozonation of Textile Wastewater: Application and Mechanism

This paper presents an overview of textile wastewater treatment by catalytic ozonation, highlighting the parameters process and accompanying mechanisms. Since more than 800,000 tons dyes are produced annually thousands cubic meters highly polluted have been emitted into environment every day, this issue has become environmental concern. Due to high oxidative potential ozone (2.08 V) hydroxyl radical (2.80 V), main reactive species in burdensome organic pollutants, including dyes, can be successfully decomposed. The shows groups catalysts, emphasizing novel structural, nano-structured, functionalized materials. examples ozonation industrial application for real were specially highlighted.
