This work focuses in the use of Fenton reagent and UV-irradiation, in a lab-scale experiment, for the treatment of real dye wastewater coming from a Spanish textile manufacturer.Response surface methodology (RSM) and a 2 3 factorial design were used to evaluate the effects of the three independent variables considered for the optimization of the oxidative process: temperature, Fe (II) and H 2 O 2 concentrations, for a textile wastewater generated during a dyeing process with chemical oxygen demand (COD) of 1705 mg·L -1 O 2 at pH = 3. Wastewater degradation was followed in terms of COD decrease.In the optimization, the correlation coefficients for the model (R The combination of Fenton, Fenton-like and photon-Fenton reactions has been proved to be highly effective for the treatment of such a type of wastewaters, and several advantages for the technique application arise from the study. Under these conditions, 120 min of treatment resulted in a 62.9 % and 76.3 % decrease in COD after Fenton and photo-Fenton treatments respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
