“…An inherent difficulty in the treatment of wastewater from kraft pulping and the bleaching of kraft pulps, is the resistance of lignin-related species to biodegradation (Lindholm-Lehto et al 2015). This problem has been often addressed by advanced oxidation processes (AOPs) (Esplugas et al 1994;Masten and Davies 1994;Hörsch et al 2003;Oller et al 2011;Merayo et al 2013;Hermosilla et al 2015).…”

“…Eriksson and Kolar (1985) employed isotopic labeling to explore the mechanisms involved in the biodegradation of such compounds. Efforts to eliminate such compounds by alternative treatment methods such as advanced oxidation processes (AOPs) have been widely reported (Rodriguez et al 1999;Pokhrel and Viraraghavan 2004;Eskelinen et al 2010;Merayo et al 2013;Lindholm-Lehto et al 2015). AOPs can be employed either as pretreatment to increase the biodegradability of the organic solids or as post-treatment to remove the remaining organic content.…”

“…Fe 3+ , may serve as mediators for the transformation of the organic compounds. Electro-oxidation has been examined by several research groups in the treatment of wastewater from P&P facilities (Mahesh et al 2006;Wang et al 2007;El-Ashtoukhy et al 2009;Särkkä et al 2009;Soloman et al 2009;Kishimoto et al 2010;Antony and Natesan 2012;Qu et al 2012;Krishna et al 2014;Lindholm-Lehto et al 2015) even using rice straw as raw material to produce paper pulp (El-Ashtoukhy et al 2009). Patel et al (2008 evaluated the removal of pentachlorophenol, as well as the treatment of pulp bleaching effluent from a bamboo-based mill, by an electrochemical process, reporting the removal of 10 mg L −1 of pentachlorophenol in less than 10 minutes when performing such treatment.…”

The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with costeffective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.

“…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.

“…Chlorophenols are introduced into the environment through the discharge of industrial or agricultural effluents that contaminate aque-ous bodies. Chlorophenols are derived from the uncontrolled use of pesticides, fungicides, and herbicides, as well as processes of degreasing metals, wood processing, and paper bleaching with chlorine, and may even be generated in the potabilization of water as a result of the chlorination of phenols formed by products of the hypochlorite reaction with phenolic acids, with 2-chlorophenol, 2,4-dichlorophenol, and 2,4,6-trichlorophenol as the most frequent occurrences in water designated for human consumption [1,2].…”

Currently, interest has grown in finding effective solutions for the treatment of water pollution by toxic compounds. Some of the latter that have acquired importance are phenols and chlorophenols, due to their employment in the manufacture of pesticides, insecticides, cords of wood, paper industry, among others. The problem is rooted in that these compounds are very persistent in the environment because they are partially biodegradable and cannot be photodegraded directly by sunlight. Chlorophenols are extremely toxic, especially 2,4,6-trichlorophenol, which is potentially carcinogenic. In this work, Mg/Al-mixed oxide catalysts were obtained from the thermal treatment of hydrotalcite-type materials, synthesized by sol-gel method with different Mg/Al ratios. Hydrotalcites and Mg/Al-mixed oxides were physicochemically characterized by X-ray diffraction, thermal analysis (DTA and TGA), and N 2 physisorption. The results were obtained on having proven the photocatalytic degradation of 2,4,6-trichlorophenol as a pollutant model by water. The catalysts obtained present the hydrotalcite phase with thermal evolution until achieving Mg/Al-mixed oxides at 500°C. The catalysts are of mesoporous materials and exhibiting large surface areas. The catalysts demonstrated good photocatalytic activity with good efficiency, reaching degradation percentages with Mg/Al = 1, 2, 4, 5, and 7 ratios of 94.2, 92.5, 86.2, 84.2, and 63.9%, respectively, until achieving mineralization.
