“…However, the decrease of COD remains low, possibly due to scavenging of hydroxyl radicals by bicarbonate and sulfate ions present in the effluent. Additionally, Fenton-like oxidation has been used in combination with ultrasonic irradiation to breakdown refractory compounds from bleaching effluents (Vilve et al 2009). Ultrasonic treatment as a pre-or post-oxidation combined with biodegradation of paper mill effluent has been reported to decrease toxicity and enhance biodegradability (Gonze et al 2003).…”

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.

“…Among AOPs, Fenton's reagent has been used (either alone or in combination with other treatments) as a chemical process for the treatment of a wide range of wastewaters. Recent applications of Fenton´s reagent include the pre-treatment of olive mill wastewater (Lucas & Peres, 2009), the treatment of landfill leachate (Deng & Englehardt, 2006;Zhang et al, 2005), copper mine wastewater (Mahiroglu et al, 2009), water-based printing ink wastewater (Ma & Xia, 2009) and cosmetic wastewaters (Bautista et al, 2007), the degradation of pesticide (Li et al, 2009;Chen et al, 2007), antibiotic (Ay & Kargi, 2010;Elmolla & Chaudhuri, 2009), high-strength livestock wastewater (Lee & Shoda, 2008) and organic compounds of nuclear laundry water (Vilve et al, 2009), the oxidation of combined industrial and domestic wastewater (Badawy & Ali, 2006), the pre-oxidation of pharmaceutical wastewaters (Martínez et al, 2003), the treatment of water-based paint wastewater (Kurt et al, 2006) and cellulose bleaching effluents (Torrades et al, 2003), the degradation of the explosives 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) after iron pretreatment (Oh et al, 2003), and the treatment of different streams of textile wastewaters, such as the treatment of hot desizing wastewaters (Lin & Lo, 1997), and the treatment of dye wastewaters (Wang et al, 2008;Gulkaya et al, 2006). Fenton´s reagent is also combined with biological process, as a pre-treatment to enhance the biodegradability of the recalcitrant compounds and lower the toxicity (Padoley et al, 2011, Mandal et al, 2010, Badawy et al, 2009 or as a post-treatment to improve the efficiency of the wastewater treatment (Ben et al, 2009, Yetilmezsoy & Sakar, 2008).…”

“…Advanced oxidation processes (AOPs) constitute a wide group of destructive methods that have been successfully used to degrade refractory organic pollutants in water [1][2][3][4][5][6][7][8][9][10][11][12]. The vast majority of photochemical AOPs use UV radiation as the source of external energy [13,14].…”

A novel process combining hydrogen peroxide (H2O2) and radiation emitted by ultraviolet light emitting diodes (UV LEDs) has been investigated. The UV LEDs were used as UV-C light sources emitting radiation in the range 257-277 nm for decomposition of the model substance phenol in water. In addition, the effect of H2O2 to phenol molar ratio and initial phenol concentration was examined. Two parameters, the decomposition efficiency of phenol and characterization of hydroxyl radical (HO*) production from H2O2 when illuminated with UV radiation, were selected to provide detailed information regarding the performance of the UV LEDs in the treatment process. A new concept was introduced to characterize and describe the production of HO* radicals produced when photons were absorbed by H2O2 molecules. The phenol decomposition efficiency at the initial concentration of 100 mg/L was the most pronounced at the lowest emitted wavelength. A significant correlation was found between the phenol decomposition efficiency and the photons absorbed by H2O2 (i.e. formation of radicals).
