The general aim of that Project is the study, design and optimization of novel processes or processes with certain level of maturity in order to implement the wastewater treatment plant (WWTP) of the 21st century. Spanish and Dutch research groups, extensively expertise in the fields related to wastewater and sewage sludge, work within that Project: from specialists on processes for wastewater and sewage sludge treatment, to specialists on related modeling, economy and ecotoxicology, among others. NovEDAR_Consolider Project encouraged conducting collaborations in between the different research groups. Thus, particularly for the case of the present PhD Dissertation, it is to be highlighted that the study to carry out and the objectives to achieve are included in the scope of the sludge line on WWTPs. The main objective consists on the study of different processes, a priori considered as high pressure processes (> 1bar), that may be implemented and optimized with the aim of improving the sewage sludge treatment and management. Energy saving and recovery is a key point in this Dissertation. In addition, a study on the anaerobic oxidation of ammonium biological process, the so called Anammox, is included in this Dissertation; the reason: the optimum implementation of this quite young process as connection between the sludge line and upstream section of the water line could involve several important benefits for the operation in novel WWTPs. The following highlighted key points are included in the present PhD Dissertation: 1.- Introducing of the Advanced Thermal Hydrolysis process (ATH), a novel pretreatment for the Anaerobic Digestion (AD) of sewage sludge: detailed comparative study with the Thermal Hydrolysis (TH) process. The ATH process takes advantage of a peroxidation plus direct steam injection synergistic effect in order to improve sewage sludge solubilization, dewaterability and biodegradability. In this work, ATH process proved to be a promising alternative from the energy saving and recovery point of view [in the sense of expediting methane (CH4) production in the AD]. A wide range of operating conditions was studied in detail: temperatures from 90 to 170 ¿C, operation times from 5 to 40 min, and with or without the addition of different hydrogen peroxide (H2O2) doses. Work conducted in collaboration University of Cádiz (Spain) - University of Valladolid (Spain). 2.- Study on the Hydrothermal Oxidation in the field of the sludge line of WWTPs. To be highlighted is the implementation of a complete kinetic study on the SCWO of Isopropanol (IPA) as auxiliary fuel/co-fuel for the optimization of the design and operation of the sewage sludge SCWO. The experimentation was conducted in a SCWO continuous flow tubular reactor system: temperatures from 400 ¿C to 500 ¿C, 250 bar and residence times from 4 to 80 seconds. The developed equations can be applied on the design, optimization and scale-up of the SCWO process in the sewage sludge treatment framework. Work carried out in the University of Cádiz (Spain). 3.- Anammox bacteria cultivation in a membrane bioreactor (MBR) looking forward to finding out the optimal operating conditions of the Anammox process, which main objective is to control/reduce the ammonium (NH4+) concentration of the WWTPs¿ effluents (the reader should take into account that NH4+ has, to some extent, a refractory behavior in the processes studied in the present PhD Dissertation: Thermal Hydrolysis, Advanced Thermal Hydrolysis, Anaerobic Digestion and Supercritical Water Oxidation). In fact, as it can be checked in the corresponding chapter of this PhD Dissertation, a cultivation of Anammox bacteria with a growth rate four-fold higher than that one commonly reported in the up to date literature.

El objetivo general de dicho proyecto consiste en llevar a cabo el estudio, diseño y optimización de procesos, ya sean novedosos o con determinado grado de madurez, para acometer la implementación de la Estación Depuradora de Aguas Residuales (EDAR) del siglo XXI. Grupos de investigación españoles y holandeses, expertos en diversos ámbitos relacionados con la depuración de aguas residuales urbanas y de los lodos producidos en dicho proceso, forman parte de este consorcio interdisciplinar europeo: trabajan en consonancia desde especialistas en el tratamiento de aguas residuales y lodos de EDAR como tal, hasta expertos en economía, simulación y ecotoxicología, entre otros. En el seno del Proyecto NOVEDAR_Consolider se incentiva establecer colaboraciones entre los distintos grupos que lo componen, las cuales faciliten la consecución de los objetivos parciales y finales del mismo. De esta forma y concretando al caso de la Tesis Doctoral aquí descrita, se debe reseñar que el estudio a desempeñar y objetivos a lograr se enmarcan en la línea de fangos de las EDARs. El objetivo último consiste en el estudio de diferentes procesos a alta presión, que puedan ser implementados y optimizados para mejorar el tratamiento y gestión de lodos de depuradora, haciendo especial hincapié en los aspectos de ahorro y recuperación energética. Adicionalmente, se incluye un estudio sobre el cada vez más extendido proceso biológico de oxidación anaerobia de amonio, conocido como Anammox, ya que son muchos los beneficios que puede conllevar la implementación óptima de este proceso como conexión entre el efluente de la línea de fangos y la cabecera de las EDARs. De la presente Memoria de Tesis Doctoral se desprenden los siguientes hitos a tener en consideración: 1.‐ Propuesta y estudio de un nuevo proceso denominado Hidrólisis Térmica Avanzada (HTA) como pretratamiento alternativo a los convencionales para mejorar el rendimiento de la posterior Digestión Anaerobia (DA) de lodos de depuradora: estudio pormenorizado y comparativo con la Hidrólisis Térmica (TH). El proceso HTA aprovecha el efecto sinérgico de la peroxidación más la adición de vapor vivo desde una caldera para mejorar la solubilización, deshidratabilidad y biodegradabilidad de los lodos EDAR. De esta forma se erige como una alternativa prometedora desde el punto de vista del ahorro y recuperación energética [en forma de metano (CH4) generado en la DA]. En cuanto a las condiciones de operación, se estudió de forma detallada un amplio rango de posibilidades: temperaturas desde los 90 оC hasta los 170 оC, tiempos de operación desde los 5 min hasta los 40 min, y con o sin adición de diferentes dosis de peróxido de hidrógeno (H2O2). Este trabajo fue realizado en colaboración Universidad de Cádiz (España) ‐ Universidad de Valladolid (España). 2.‐ Estudio de la Oxidación hidrotérmica en el ámbito de la línea de fangos EDAR. Se ha llevado a cabo un completo estudio cinético de la Oxidación en Agua Supercrítica (OASC) del Alcohol isopropílico (o Isopropanol, C3H8O) como combustible auxiliar/co‐ combustible para optimizar el diseño y operación de la OASC de lodos de EDAR. Se utilizó un sistema a escala de laboratorio con reactor tubular para la operación en continuo en condiciones supercríticas: temperaturas desde los 400 оC a los 500 оC, a una presión de 250 bar y tiempos de residencia aproximados desde los 4 a los 80 segundos. Las ecuaciones cinéticas desarrolladas tiene una aplicación práctica directa en futuros estudios de diseño, optimización y escalado de la OASC en el ámbito del tratamiento de lodos EDAR. Este trabajo se realizó en la Universidad de Cádiz (España). 3.‐ Cultivo de bacterias Anammox en un reactor biológico de membrana (MBR) en busca de las condiciones óptimas de operación del proceso Anammox, cuyo principal objetivo es el control/reducción de la concentración de amonio (NH4+) en el efluente de las EDARs (el lector debe tener en cuenta que el NH4+ presenta, en cierto modo, un comportamiento refractario en los procesos estudiados en la presente Tesis Doctoral: Hidrólisis Térmica, Hidrólisis Térmica Avanzada, Digestión Anaerobia y Oxidación en Agua Supercrítica). De hecho, como se verá en el correspondiente capítulo de la presente Tesis Doctoral, se ha logrado cultivar las bacterias Anammox con una tasa de crecimiento aproximadamente cuatro veces superior que la comúnmente reportada en la bibliografía hasta la fecha.
