Exploring reuse of industrial wastewater from exhaust dyebaths by solar-based photo-Fenton treatment
The aim of the research under discussion in the present paper is to study the decolorization and mineralization of textile industrial wastewaters from exhaust dyebaths by means of a solar photo-Fenton treatment. The exhaust dyebaths were grouped according to the fibers and dyeing recipes used, so as to verify the effectiveness of the photo-Fenton treatment on each dyeing process separately. Next, the results previously achieved were compared to those obtained by mixing all the exhaust baths together, as is common practice when treating the industrial textile effluents from dyeing and finishing procedures. After their neutralization and filtration, photo-Fenton-treated exhaust dyebaths and mixtures were reused to prepare laboratory dyeing samples. These techniques on the reuse of wastewaters were tested on several fibers by using the same dyeing procedure that was originally applied, as well as in different dyeing processes and for most fiber types. The results achieved showed that the reutilization of the aforementioned effluents, either in new exhaust dyebaths or in some other textile industrial operations, was of some considerable importance. Water consumption would be significantly reduced as well as the wastewater levies for the firms. Furthermore, the contaminating effect of the industrial effluents to be dealt with would be also diminished, reaping environmental and economic benefits.Sanz Carbonell, JF.; Monllor Pérez, P.; Vicente Candela, R.; Amat Payá, AM.; Arques Sanz, A.; Bonet Aracil, MA.

Photo-Fenton reaction at mildly acidic conditions: assessing the effect of bio-organic substances of different origin and characteristics through experimental design
This is an Author's Accepted Manuscript of an article published in Arlen Mabel Lastre-Acosta, Rafael Vicente, Margarita Mora, Ulises Javier Jáuregui-Haza, Antonio Arques & Antonio Carlos Silva Costa Teixeira (2019) Photo-Fenton reaction at mildly acidic conditions: assessing the effect of bio-organic substances of different origin and characteristics through experimental design, Journal of Environmental Science and Health, Part A, 54:8, 711-720 [copyright Taylor & Francis], available online at: http://www.tandfonline.com/10.1080/10934529.2019.1585721[EN] Urban-waste bio-organic substances (UW-BOS) have been shown to be capable of extending the photo-Fenton reaction to mildly acidic conditions. In this study, the effects of pH (3-7), UW-BOS, H2O2 and iron concentrations on the photo-Fenton process were systematically assessed using a Doehlert experimental design and response surface methodology for two UW-BOS (CVT230 and FORSUD). Solutions of the model antibiotic sulfadiazine (SDZ) were irradiated in a solar simulator equipped with a 550W Xenon lamp. The results showed that for UW-BOS contents below 30mg L-1, SDZ removal proceeds at pH 5 with similar rates for both CVT230 and FORSUD, regardless of Fe(III) concentration. For 50mg L-1 of UW-BOS or higher, CVT230 performs better than FORSUD, even for low Fe(III) content (1-3mg L-1). In contrast, half-life times of 35-40min can only be achieved under mildly acidic conditions with FORSUD for iron concentrations higher than 10mg L-1. The better performance of CVT230 can be associated with its high hydrophilic/hydrophobic ratio, low E2:E3, higher iron content and possibly higher yields of triplet reactive species generation upon solar irradiation. The most appropriate conditions for each UW-BOS studied are discussed for the first time, which are advantageous for possible engineered applications.The authors express their gratitude to CNPq (National Council for

Humic-like substances from urban waste as auxiliaries for photo-Fenton treatment: a fluorescence EEM-PARAFAC study
[EN] In this work, analysis of excitation-emission-matrices (EEM) has been employed to gain further insight into the characterization of humic like substances (HLS) obtained from urban wastes (soluble bio-organic substances, SBOs). In particular, complexation of these substances with iron and changes along a photo-Fenton process have been studied. Recorded EEMs were decomposed by using parallel factor analysis (PARAFAC). Three fluorescent components were identified by PARAFAC modeling of the entire set of SBO solutions studied. The EEM peak locations (lambda(ex)/lambda(em)) of these components were 310-330 nm/400-420 nm (C1), 340-360 nm/450-500 nm (C2), and 285 nm/335-380 nm (C3). Slight variations of the maximum position of each component with the solution pH were observed. The interaction of SBO with Fe(III) was characterized by determining the stability constants of the components with Fe(III) at different pH values, which were in the order of magnitude of the ones reported for humic substances and reached their highest values at pH = 5. Photochemical experiments employing SBO and Fe(III), with and without H2O2, showed pH-dependent trends for the evolution of the modeled components, which exhibited a strong correlation with the efficiency reported for the photo-Fenton processes in the presence of SBO at different pH values.This work was supported by Generalitat Valenciana, Conselleria d'Ecuacio, Cultura i esport, Spain (GV/2015/074), Spanish Ministerio de Economia y Competitividad (CTQ2015-69832-C4-4-R) and by the Marie Sklodowska-Curie Research and Innovation Staff Exchange project funded by the European Commission H2020-MSCA-RISE-2014 (Project number: 645551).

Treatment and reuse of textile wastewaters by mild solar photo-Fenton in the presence of humic-like substances
The final publication is available at Springer via http://dx.doi.org/10.1007/s11356-016-7889-1In this paper, the possibility of reusing textile effluents for new dyeing baths has been investigated. For this purpose, different trichromies using Direct Red 80, Direct Blue 106, and Direct Yellow 98 on cotton have been used. Effluents have been treated by means of a photo-Fenton process at pH 5. Addition of humic-like substances isolated form urban wastes is necessary in order to prevent iron deactivation because of the formation of non-active iron hydroxides. Laboratory-scale experiments carried out with synthetic effluents show that comparable results were obtained when using as solvent water treated by photo-Fenton with SBO and fresh deionized water. Experiments were scaled up to pilot plant illuminated under sunlight, using in this case a real textile effluent. Decoloration of the effluent could be achieved after moderate irradiation and cotton dyed with this water presented similar characteristics as when deionized water was used.This work was realized with the financial support of a Marie Sklodowska-Curie Research and Innovation Staff Exchange project funded by the European Commission H2020-MSCA-RISE-2014 within the framework of the research project Mat4treaT (project number 645551).

A new methodology to assess the performance of AOPs in complex samples: Application to the degradation of phenolic compounds by O3 and O3/UV-A Vis
[EN] A methodology combining experimental design methodology, liquid chromatography, excitation emission matrixes (EEM) and bioassays has been applied to study the performance of O3 and O3/UVA-vis in the treatment of a mixture of eight phenolic pollutants. An experimental design methodology based on Doehlert matrixes was employed to determine the effect of pH (between 3 and 12), ozone dosage (02¿1.0¿g/h) and initial concentration of the pollutants (1¿6¿mg/L each). The following conclusions were obtained: a) acidic pH and low O3 dosage resulted in an inefficient process, b) increasing pH and O3 amount produced an enhancement of the reaction, and c) interaction of basic pH and high amounts of ozone decreased the efficiency of the process. The combination of O3/UVA-vis was able to enhance ozonation in those experimental regions were this reagent was less efficient, namely low pH and low ozone dosages. The application of EEM-PARAFAC showed four components, corresponding to the parent pollutants and three different groups of reaction product and its evolution with time. Bioassys indicated important detoxification (from 100% to less than 30% after 1¿min of treatment with initial pollutant concentration of 6¿mg/L, pH¿=¿9 and ozone dosage of 0.8¿g/h) according to the studied methods (D. magna and P. subcapitata). Also estrogenic activity and dioxin-like behavior were significantly decreased.The authors thank the financial support of the European Union(PIRSES-GA-2010-269128, EnvironBOS) and Spanish Ministerio de Educación y Ciencia (CTQ2015-69832-C4-4-R).

Humic like substances extracted from oil mill wastes in photo-Fenton processes: Characterization, performance and toxicity assesment
[EN] Olive mill waste has been used as sourcing materials for the isolation of humic like substances (OMW-HLS) which have demonstrated its capacity to expand the range of applicability of photo-Fenton process to pH= 5. During the isolation process, membranes of three different pore sizes (300 kDa, 150 kDa and 50 kDa) were employed in order to obtain three batches of OMW-HLS. Four pollutants contained in 2013/39/EC were used as target substances: terbutryn (TBT), diclofenac (DCF), chlorfenvinphos (CVF) and pentachlorophenol (PCP). Results showed that OMW-HLS was able to enhance photo-Fenton at pH = 5, but differences were not significant, either among fractions or with commercial humic substances. Reactions were scaled-up and driven under real sunlight and pollutants removal was faster in the presence of OMW-HLS. Toxicity was monitored according to bioassays based on different organisms or cell lines. Detoxification was observed with and without OMW-HLS, although higher toxicity was detected in the presence of humic acids, most probably due to the surfactant effect, that allows a better contact between pollutant and organism.The authors thank the financial support of the European Union H2020 (2018-2022) (Ref. 776816) Proyect O, and Spanish Ministerio de Ciencia, Innovacion y Universidad (RTI 2018-097997-B-C31) .

New Route for Valorization of Oil Mill Wastes: Isolation of Humic-Like Substances to be Employed in Solar-Driven Processes for Pollutants Removal
[EN] The valorization of olive oil mill solid wastes (OMW) has been addressed by considering it as a possible source of humic-like substances (HLSs), to be used as auxiliary substances for photo-Fenton, employing caffeine as a target pollutant to test the efficiency of this approach. The OMW-HLS isolation encompassed the OMW basic hydrolysis, followed by ultrafiltration and drying. OMW-HLS structural features have been investigated by means of laser light scattering, fluorescence, size exclusion chromatography, and thermogravimetric analysis; moreover, the capability of OMW-HLS to generate reactive species under irradiation has been investigated using spin-trap electronic paramagnetic resonance. The caffeine degradation by means of photo-Fenton process driven at pH = 5 was significantly increased by the addition of 10 mg/L of OMW-HLS. Under the mechanistic point of view, it could be hypothesized that singlet oxygen is not playing a relevant role, whereas other oxidants (mainly OH center dot radicals) can be considered as the key species in promoting caffeine degradation.Authors want to acknowledge the financial support of Spanish Ministerio de Economia y Competitividad (CTQ2015-69832-C04) and European Union (645551-RISE-2014, MAT4-TREAT).García-Ballesteros, S.; Grimalt, J.; Berto, S.; Minella, M.; Laurenti, E.; Vicente Candela, R.; López Pérez, MF....

Reutilización en nuevas tinturas de aguas industriales reales tratadas mediante proceso foto-Fenton (I)
[EN] Textile wastewaters have a potential impact on the environment, therefore, reuse of these effluents represents an economic and ecological benefit. The appropriate depuration by firms after textile dyeing and finishing operations needs the application of efficient and adequate wastewater treatments. Processes known as Advanced Oxidation Processes (AOP) used in the decolorization and mineralization of wastewaters are extremely effective. AOPs using solar light, as the photo-Fenton process, are especially interesting for the treatment of textile effluents. 99% decrease in absorbance of the industrial textile effluents treated, from exhausting dyeing, has led to its re-use in new laboratory dyeing of several textile materials, by using a range of dyestuffs with diverse chromoferes.[ES] Los efluentes generados por las industrias textiles representan un problema potencial para el medioambiente. Su tratamiento antes de ser liberados en cauces públicos o estaciones depuradoras de aguas residuales (EDAR), implica la aplicación de tratamientos eficientes. Las técnicas conocidas como Procesos Avanzados de Oxidación PAOs para la depuración de aguas son especialmente efectivas, tanto por su elevada reactividad como por su poca selectividad oxidativa. Entre los PAOs, los procesos foto-Fenton resultan muy interesantes para el tratamiento de efluentes textiles, especialmente aquellos que emplean la luz del sol. La disminución del 99% en la absorbancia de los efluentes industriales, de tintura por agotamiento, tratados, ha permitido su reutilización para tintar a escala de laboratorio diferentes materias textiles con diversas familias de colorantes.Sanz, JF.; Monllor Pérez, P.; Vicente Candela, R.; Vercher Pérez, RF.

Polyamide 6.6 Degradation through Photo-Fenton Process
[EN] Synthetic polymers have become essential in our life, nevertheless, the high production and the low recycling around the world have caused serious problems of contamination in soil and water. In addition, its fragmentation into microplastics in environmental conditions has exacerbated the ecological problems due to its possible ingestion by organisms and its high capacity to transport and release a wide variety of organic pollutants. Photo-Fenton process was used to evaluated its capacity to degrade PA6.6 microplastic under simulated solar irradiation and natural solar irradiation plus LED visible light in order to get a best knowledge about its behavior in environmental conditions. PA6.6 was degraded for 7 h through photo-Fenton process under simulated solar irradiation. Superficial defects were observed along the PA6.6 microplastic after degradation experiments. However, FT-IR analysis did not show the formation of additional bands which indicated the formation of new products. DSC analysis showed changes in the melting point of the PA6.6 after the photo-Fenton treatment at different times. The assays carried out under natural solar irradiation showed lower degradation of the PA6.6 under the same experimental conditions, nevertheless, it was observed an increase of the specific surface area 90 times higher in the PA6.6 treated for 10 h.The authors wish to thank the Spanish Ministry of Science, Innovation and Universities (MCIU) for
