“…Due to the irreparable effects of dyes especially the methylene blue, and the increased use of these dyes, which are a serious threat to the environment and the health of communities, the removal of colorants in industries containing these dyes is of particular importance. Several studies have also shown that Fenton processes have high efficiency in removing dye from colored wastewater .…”

In this article, degradation of Methylene Blue by Fenton's oxidation process was investigated. The effect of, Fe2+ and H2O2 concentrations and reaction time in initial concentration of the dye = 10 mg/L, pH = 3 and lab temperature on the dye removal was studied. Also, Artificial Neural Networks (ANN) was applied to model the dye removal data obtained by Fenton oxidation process. A network consisting of two layers of eight neurons in the hidden layer was considered. Very low root mean squared error (RMSE) of 1.262 and high determination of coefficient (R2) of 0.995 in the network calculation verified validity of the acquired network for further analysis and optimization. © 2018 American Institute of Chemical Engineers Environ Prog, 39:e13126, 2020

“…Fenton was mainly responsible for the metabolites' degradation-up to 90%. In the case of full-scale industrial textile wastewater treatment, the Fenton process significantly improved color and COD removal (66 and 73%, respectively) obtained in pure-oxygen activated sludge treatment [242]. Ribeiro et al [243] tested whether Fenton process may be used as a polishing step enabling water reuse.…”

In the last 3 years alone, over 10,000 publications have appeared on the topic of dye removal, including over 300 reviews. Thus, the topic is very relevant, although there are few articles on the practical applications on an industrial scale of the results obtained in research laboratories. Therefore, in this review, we focus on advanced oxidation methods integrated with biological methods, widely recognized as highly efficient treatments for recalcitrant wastewater, that have the best chance of industrial application. It is extremely important to know all the phenomena and mechanisms that occur during the process of removing dyestuffs and the products of their degradation from wastewater to prevent their penetration into drinking water sources. Therefore, particular attention is paid to understanding the mechanisms of both chemical and biological degradation of dyes, and the kinetics of these processes, which are important from a design point of view, as well as the performance and implementation of these operations on a larger scale.

“…However, the treatment facilities target easily biodegradable organic matter, rather than refractory non-biodegradable organic matter, as long as the facilities can comply with traditional regulations for Depending on the type of industry, some industrial discharges are abundant in NBDSCOD, and thus, more refractory in a biological treatment process. For example, it has been reported that dyeing factories discharge a large amount of NBDSCOD [4,8,9]. Because many chemical dyes are based on aromatic or heterocyclic ring structures, which are considered non-biodegradable, industrial discharge from dyeing factories likely contains substantial amounts of NBDSCOD.…”

“…In addition, industrial discharge from paper mill factories was reported to contain a large amount of lignin and lignin derivatives, which are also known to be non-biodegradable, and hence, increase the amount of NBDSCOD [10,11]. An advanced oxidation process might be required to degrade NBDSCOD containing aromatic compounds from dyeing and paper mill factories [9,12].…”

Municipal wastewater treatment plants (WWTPs) in Korea collect and treat not only domestic wastewater, but also discharge from industrial complexes. However, some industrial discharges contain a large amount of non-biodegradable organic matter, which cannot be treated properly in a conventional biological WWTP. This study aimed to investigate the characteristics and biodegradability of the wastewater organic matter contained in the industrial discharges and to examine the fate of the industrial discharges in a biological WWTP. In contrast to most previous studies targeting a specific group of organic compounds or traditional water quality indices, such as biological oxygen demand (BOD) and chemical oxygen demand (COD), this study was purposed to quantify and characterize the biodegradable and nonbiodegradable fractions of the wastewater organic matter. Chemical oxygen demand (COD) fractionation tests and fluorescence spectroscopy revealed that the industrial discharge from dyeing or pulp mill factories contained more non-biodegradable soluble organic matter than did the domestic wastewater. Statistical analysis on the WWTPs' monitoring data indicated that the industrial discharge containing non-biodegradable soluble organic matter was not treated effectively in a biological WWTP, but was escaping from the system. Thus, industrial discharge that contained non-biodegradable soluble organic matter was a major factor in the decrease in biodegradability of the discharge, affecting the ultimate fate of wastewater organic matter in a biological WWTP. Further application of COD fractionation and fluorescence spectroscopy to wastewaters, with various industrial discharges, will help scientists and engineers to better design and operate a biological WWTP, by understanding the fate of wastewater organic matter.
