    This article presents experimental results on 47 mu mol L-1 sulfathiazole (STZ) degradation by Fenton and photo-Fenton reactions using multivariate analysis. The optimal experimental conditions for reactions were obtained by Response Surface Methodology (RSM). In the case of the Fenton reactions there were 192 mu mol L-1 ferrous ions (Fe(II)) and 1856 mu mol L-1 hydrogen peroxide (H2O2), as compared with 157 mu mol L-1 (Fe(II)) and 1219 mu mol L-1 (H2O2) for photo-Fenton reactions. Under these conditions, around 90% of STZ degradation were achieved after 8 minutes treatment by Fenton and photo-Fenton reactions, respectively. Moreover, a marked difference was observed in the total organic carbon (TOC) removal after 60-min treatment, achieving 30% and 75% for the Fenton and photo-Fenton reactions, respectively. Acetic, maleic, succinic and oxamic acids could be identified as main Fenton oxidation intermediates. A similar pattern was found in the case of photo-Fenton reaction, including the presence of oxalic acid and ammonia at short periods of irradiation with UV-A. The calculated values of Average Oxidation State (AOS) corroborate the formation of oxidized products from the initial steps of the reaction.

    Despite being acknowledged as an emerging contaminant, sulphamethazine (SMT) degradation has received scarce attention in the advanced oxidation processes field. Thus, this work addresses the degradation of SMT in water solutions (12L of 25mgL(-1) samples) by means of a photo-Fenton process and a systematic H2O2 dosage protocol that enhances its performance. A conventional photo-Fenton process led to 86% mineralization after 120min treatment when adding the Fenton reactants at once (initial concentrations were 10mgL(-1) Fe(II) and 200mgL(-1)H(2)O(2)). Conversely, the process achieved the total mineralization of the samples in less than 75min when the same amount of H2O2 was continuously dosed according to a conveniently tuned dosage protocol. In both cases, total SMT degradation was achieved within 10min. Hence, this work's aim is to determine the efficient dosage conditions of H2O2. The results show that a significant improvement of the photo-Fenton mineralization of SMT solutions is possible by adjusting the dosage of H2O2.

    The remediation of water solutions containing tetracycline antibiotic (TC) using photo-Fenton treatments has received scarce attention in the literature. However TC deserves attention due to its condition of emerging contaminant. In this work, TC oxidation in water solutions (12 L, 40 mg L-1) by means of photo- Fenton reaction under variable hydrogen peroxide dosage is investigated. This shows a more efficient use of the hydroxyl radicals produced in the reaction medium and enhances treatment performance. First, a suitable range of Fenton reagent loads is determined in a preliminary study. The hydrogen peroxide dosage is parameterized through two variables: The initial release of the total load, y0 (kick-off), and the time tini at which the continuous dosage of the rest of the load starts. Hence, a design of experiments (22) can be used to characterize the performance of the process under different hydrogen peroxide dosage protocols. The results obtained this way show that total TC remediation is attained in all the cases studied, but alike amounts of hydrogen peroxide lead to total mineralization only when the dosage scheme is conveniently tuned. Therefore, the photo-Fenton treatment has proved to be effective in removing TC from water solutions, and the opportunity for an efficient dosage to reduce the requirements of hydrogen peroxide has also been confirmed. © 2013 Elsevier B.V.

    The aim of the present study was to compare the degradation kinetics of low (1 mg L-1) and high (25 mg L-1) concentrations of ciprofloxacin (CIP) aiming to decrease the concentration of additives and evaluate the pH limitation by the use of low iron concentrations and organic ligands. A parameterized kinetic model was satisfactorily fitted to the experimental data in order to study the performance of photo-Fenton process with specific iron sources (iron citrate, iron oxalate, iron nitrate) under different pH medium (2.5, 4.5, 6.5). The process modeling allowed selecting those process conditions (iron source, additives concentrations and pH medium) which maximize the two performance parameters related to the global equilibrium conversion and kinetic rate of the process. For the high CIP concentration, degradation was very influenced by the iron source, resulting in much lower efficiency with iron nitrate. At pH 4.5, highest TOC removal (0.87) was achieved in the presence of iron citrate, while similar CIP conversions were obtained with oxalate and citrate (0.98 after 10 min). For the low CIP concentration, much higher conversion was observed in the presence of citrate or oxalate in relation to iron nitrate up to pH 4.5. This behavior denotes the importance of complexation also at low dosages. Appropriate additives load (320 mu M H2O2; 6 mu M Fe) resulted in a CIP conversion of 0.96 after 10 min reaction with citrate up to pH 4.5.

    This work addresses the optimization of the batch process recipe of an Advanced Oxidation Process (AOP) aimed at reducing paracetamol (PCT) and Total Organic Carbon (TOC) concentrations from a given effluent. The kinetic model by Cabrera Reina et al. (2012) is adapted to model the treatment, the problem is next formulated as a dynamic optimization problem and dosage of hydrogen peroxide is addressed by means of a piecewise constant strategy, which is compared with other dosage protocols. Results show that cost reductions can be obtained when applying the model-based optimization techniques proposed, and hint new opportunites for AOPs enhancement

    El aumento de la densidad poblacional en algunas zonas del planeta y los cada vez más rápidos avances en las áreas tecnológicasy energéticas han traído como consecuencia un crecimiento notable en los requerimientos de bienes y servicios, lo que a su vez haocasionado una sobreexplotación y una consecuente contaminación de los recursos ambientales. El agua, un recurso norenovable, no escapa de los efectos nocivos de la actividad humana y los crecientes niveles de contaminación que la afectanamenazan con interferir con el desarrollo normal de los ecosistemas y, eventualmente, de la vida misma.En las últimas décadas, se ha detectado la presencia de una nueva generación de contaminantes en aguas residuales,superficiales, subterráneas e incluso potables. Estos contaminantes, llamados ¿contaminantes emergentes¿, no son aún objeto deregulación, pero su carácter recalcitrante y sus efectos como disruptores endocrinos sugieren que su bio-acumulación tendrágraves consecuencias. Al no ser biodegradables, no es posible removerlos en las plantas de tratamiento de aguas convencionales,por lo que se requiere de un proceso químico que los oxide al menos a contaminantes más biodegradables y/o no tóxicos. Losprocesos de oxidación avanzada han demostrado ser particularmente útiles en la degradación y eventual mineralización decontaminantes emergentes, pero la complejidad de sus mecanismos y los altos costos de reactivos y energía que involucranobligan a investigar opciones para mejorar su desempeño.El objetivo de esta tesis consiste en investigar y proponer alternativas para mejorar el desempeño del proceso foto-Fenton, unproceso de oxidación avanzada ampliamente utilizado que ha demostrado ser eficiente en la degradación de contaminantesorgánicos recalcitrantes. Para tal fin, se cumplieron los siguientes objetivos específicos: un estudio detallado de las variablesinvolucradas en el proceso, la mejora del proceso a través de una dosificación sistemática del peróxido de hidrógeno, la simulacióndel proceso bajo las condiciones de adición propuestas y la investigación de una alternativa de optimización para la reducción decostos operativos.En la primera fase de la investigación, a través del mencionado enfoque experimental, se estudian las variables involucradas en elproceso y se propone un protocolo de adición de peróxido de hidrógeno novedoso, flexible y de fácil implementación que mejora demanera considerable la mineralización de soluciones acuosas de tres contaminantes emergentes, llegando en algunos casoshasta la total eliminación del carbono orgánico total. Sin embargo, la efectividad del protocolo de adición propuesto se vefuertemente influenciada por el efecto cruzado entre los parámetros involucrados.En una etapa posterior, de carácter computacional, se simula el proceso con el protocolo de adición propuesto, de modo que puedepredecirse fácilmente la mejora del desempeño del proceso cuando los parámetros del protocolo se ajustan de maneraconveniente. En un paso más allá, en la búsqueda de una herramienta que permita identificar la mejor combinación de losparámetros que controlan la adición del peróxido de hidrógeno, se investiga la optimización de la operación batch, demostrándoseque es posible reducir los costos del proceso sin desmejora de la calidad del producto.Para concluir, esta tesis supone un paso hacia adelante en el mejoramiento de los procesos de oxidación avanzada y abre laspuertas a continuar investigando propuestas de modelaje, simulación y optimización de estos complejos procesos.

    The growth of population density in some areas of the planet and the increasing fast advances in technology and energy issues, have resulted in a remarkable increment in the necessity for goods and services, with a subsequent over-exploitation and pollution of the environmental resources. Water, a non-renewable resource, does not escape from the harmful effects of human activity and its increasing pollution levels threaten the normal development of ecosystems and life as well. In the last decades, the occurrence of a new generation of contaminants has been detected in wastewaters, surface and underground waters, and even in drinking water. These substances, called "emerging contaminants" or "emerging pollutants", are not subject to regulation, but their recalcitrant character and their effects as endocrine disruptors suggest that their bio-accumulation will have severe consequences to the environment. These non-biodegradable compunds cannot be removed in conventional wastewater treatment plants, and there is a need for chemical processes to oxidize them at least to bio-degradable or non-toxic species. Advanced oxidation processes (AOPs) have demonstrated to be particularly useful in degrading and eventually mineralizing emerging contaminants, but the complexity of their mechanisms and the high reagent and energy costs involved, make necessary to develop options to improve their performance. This thesis specifically addresses the photo-Fenton process, an advanced oxidation process which has been widely applied and has demonstrated to be efficient in the degradation of recalcitrant organic contaminants. The objective of this thesis is to investigate and to propose operating alternatives to improve the performance of photo-Fenton process. For that aim, it was necessary to fulfill some specific objectives: to perform a detailed study of the variables involved in the process, propose its enhancement throughout a systematic dosage of hydrogen peroxide along the treatment span, simulate the process and to investigate opportunities to optimize the process batch recipe. In the first stage of the investigation, with a clear experimental approach, the variables involved in the process were studied and a novel, flexible and easy-to-implement hydrogen peroxide systematic dosage protocol was proposed, improving the mineralization of three emerging contaminants, reaching almost total mineralization in some of the cases. However, the effectiveness of the protocol is strongly influenced by the crossed effect between the involved parameters. In a subsequent stage, a computational approach, the process involving the proposed dosage protocol is simulated and the performance of the process was predicted at different operational conditions. The opportunities for improving process performance when the parameters concerning the dosage protocol are conveniently adjusted can be addressed. Finally, taking a step forward, a first attempt to investigate the alternatives for process optimization was investigated, demonstrating that operational costs can be reduced without diminishing the quality of the final product. As a final remark, this thesis supposes a step forward in the improvement of advanced oxidation processes and it opens the door to continue developing strategies to model, simulate and optimize these complex processes.

    Photodegradation of Paracetamol by photo-Fenton process E. Yamal-Turbay1, E. Ortega1, M. Graells1, H. D. Mansilla2, O. M. Alfano3, M. Pérez-Moya1 1Universidad Politécnica de Cataluña, Departamento de Ingeniería Química, Barcelona, España.

The presence of pharmaceuticals in surface water, sewage treatment plant effluents (STP) and groundwater waters has been recently reported to be an environmental issue of great significance because of its consequences over ecosystems and human health. Photo-Fenton process has shown to be effective as an alternative to remediate wastewaters containing this kind of contaminants and it can be used before or after conventional treatments. Although this process has been widely studied, a lot of work is still required in order to develop a practical understanding of its performance so that the operational conditions can be determined to exploit it efficiently in terms of economical and environmental costs. In this work, the photo-Fenton degradation of solutions pharmaceutical such as paracetamol (PCT) (15 L, 40 mg L-1) has been addressed. The treatment performance has been analyzed under a factorial design and the efficiency of the degradation process has been evaluated considering the decay of PCT and total organic carbon (TOC) concentrations and the biological oxygen demand, BOD5. Light influence has also been assessed and the photonic efficiency for the photooxidation of paracetamol by photo-Fenton process has been determined. Finally, data obtained from the assays performed are discussed and compared. Results characterizing the treatment output dependence on factors such as hydrogen peroxide, iron (II) and photonic efficiency, allow determining enhanced conditions for the photo-Fenton degradation of paracetamol solutions.

    La incorporación de la lengua inglesa en la formación superior es algo que en el siglo XXI no admite discusión. Sin embargo, no parece que exista un único modelo para llevarlo a cabo, tanto en el fondo como en la forma. Este trabajo discute algunos modelos, ventajas e inconvenientes, y analiza y valora la experiencia de incluir en la formación clases en inglés impartidas por profesores visitantes, cuya principal ventaja estriba en el hecho de que la comunicación en inglés se convierte en una necesidad real para acceder a los conocimientos que viene a aportar a la clase un especialista de otro país. El programa Erasmus, además, es un medio poco explotado que facilita el intercambio de profesorado y fomenta el aprendizaje en inglés.

    A novelty detection approach for detecting novel faults has been developed and applied to a photo-Fenton process in a fully monitored pilot plant. The proposed approach consists of two stages: Fault Detection or binary classification stage, and Fault Diagnosis (FD) or multi-class classification stage. Batches under nominal operating conditions, where coffee samples are degraded, are defined according to an experimental design and three possible faults are found in the process. Experimental batches under such normal and abnormal conditions are used to construct the classification models and therefore, the novelty detection approach. Two faulty batches, not learned by the models, were used to validate the approach. The successful results obtained encourage performing potential models for other pollutants that allow further detecting novel contaminants in wastewater treatments.

    Emergent contaminants, recently detected in wastewaters such as human and veterinary pharmaceuticals, have turn into an environmental and health concern [1]. Among pharmaceuticals, antibiotics need to be highlighted because they cause bacteria resistance and harmful effects to organisms [2]. In this context, the development and application of efficient treatment processes aimed at degrading antibiotics from wastewaters has arisen as a mean to reduce environmental impact and health risk. This communication presents some relevant results of the study of the degradation of two different emergent pollutants from the group of antibiotics recently detected in wastewaters: Tetracycline (TC) and Sulfamethazine (SMT) [3,4].

    The impact and significance of a training process may not be easily noticeable in the short term, and is difficult to track in the long term. This is more common when training targets are acquiring positive attitudes and competences (i.e. environmental awareness) rather than specific technical procedures. Thus, such training requires specific evaluation tools for quantifying the degree of achievement the objectives. Microteaching is a training methodology characterized by brevity and flexibility, which focuses in promoting active learning and evaluating its long-term impact (including performance indicators). The methodology was developed during two European projects (Leonardo da Vinci Programme(Overschie,2006; Pérez-Moya, 2008, www.microtrainingsupport. eu/).
