Abstract
A statistical design of experiments was used to evaluate the potential use of clay catalyst (CuOFeB) during photo-Fenton process in which the concentration of hydrogen peroxide (H2O2), catalyst loading and pH values were select-ed as effective experimental factors in the process of dye decolorization. The photo-Fenton oxidation of Reactive Red 120 (RR120) has been investigated using a concentrating solar parabolic reactor with constant solar radiation of 950 W/m2 during summer period of the year. Under the optimal reaction conditions catalyst showed good catalytic activity in the processes with dye removal over 90%. Also, experiment confirmed that decolorization efficiency depends on the pH and concentration of H2O2 , wherein better results were achieved under lower pH values and higher concentration of H2O2.

IntroductionIn the textile industry wastewater is treated with various physical-chemical (coagulation, flocculation, ozonisation, gravity separation, filtration methods, adsorption, etc.) and biological treatments (removal of nitrogen, phosphorus, organic matter etc.) (Chandran, 2016; Urbas et al, 2016; Boczkaj and Fernandes, 2017)

In recent years, advanced oxidation processes (AOPs) have been Journal of Graphic Engineering and Design, Volume 9 (2), 2018. 33 studied in order to apply new methods for the treatment of organic wastewater (Glaze, Kang and Chapin, 1987; Wanget al., 2016) defined AOPs as water treatment processes characterized by generating reactive hydroxyl radicals at room temperature and atmospheric pressure (Pouran, Aziz and Ashri Wan Daud, 2015)
Summary
In the textile industry wastewater is treated with various physical-chemical (coagulation, flocculation, ozonisation, gravity separation, filtration methods, adsorption, etc.) and biological treatments (removal of nitrogen, phosphorus, organic matter etc.) (Chandran, 2016; Urbas et al, 2016; Boczkaj and Fernandes, 2017). Wastewater with very low organic load (in ppb) containing dissolved organic compounds that are difficult to remove can be treated with advanced oxidation processes (Pouran, Aziz and Ashri Wan Daud, 2015; Boczkaj and Fernandes, 2017). This process shows high efficiency of oxidation of organic pollutants and inactivation of microorganisms in wastewater (Villegas-Guzman et al, 2017).
