Book excerpt: Existe una creciente preocupación medioambiental debida la presencia de microcontaminantes orgánicos en los sistemas acuáticos. La escasa eficiencia en la degradación de contaminantes orgánicos persistentes en las plantas de tratamiento de aguas residuales convencionales basadas en procesos biológicos constituye uno de los principales fuentes de su emisión en el medio ambiente. Esto significa la liberación continua en el ciclo del agua de sustancias que aunque se encuentran en muy bajas concentraciones, han sido reconocidas como potencialmente peligrosas para el medio ambiente y la salud humana. Por tanto, para la eliminación de estas sustancias se está investigando la inclusión de un tratamiento terciario en las estaciones depuradoras de aguas residuales. En este respecto, los procesos de oxidación avanzada (POA) han sido ampliamente investigados debido a la generación de radicales hidroxilos altamente reactivos, capaces de oxidar compuestos orgánicos. Entre ellos, el proceso foto-Fenton ha demostrado ser eficaz en la eliminación de microcontaminantes. Sin embargo, todavía se necesita investigar en la operación de este proceso para su aplicación en plantas de tratamiento de aguas residuales a escala real. Este trabajo ha sido diseñado para evaluar diferentes estrategias de operación del proceso foto-Fenton como tratamiento terciario para eliminar microcontaminantes en efluentes secundarios de la industria agroalimentaria (“Cítricos del Andarax S.A.”, Almería, España) y de plantas de tratamiento de aguas residuales municipales. La evaluación se ha realizado en función de las características de las distintas matrices de agua así como por la viabilidad de escalar el proceso a niveles reales utilizando un reactor de bajo costo tipo “raceway”. Los reactores “raceway” son fotorreactores extensivos formados por canales donde el líquido es movido por un agitador de palas y que permiten tratar grandes volúmenes de agua. En resumen, el trabajo presentado en esta tesis muestra que controlar el pH durante la depuración biológica de aguas residuales de industria agro-alimentaria facilita la eliminación de microcontaminantes mediante el proceso de foto-Fenton y que reduce los costes de reactivos. Además, el exceso de fango generado durante el tratamiento biológico puede ser reducido por ultrasonicación del fango purgado y degrada la mayoría de los plaguicidas absorbidos en el fango. Por otro lado, los reactores tipo “raceway” permiten altas capacidades de tratamiento para la eliminación de microcontaminantes mediante procesos de Fenton solares como la dosificación secuencial de hierro y el uso del complejo Fe3+/EDDS, habiendo demostrado ser tratamientos eficientes en la eliminación de microcontaminates y toxicidad en efluentes secundarios de depuradoras de aguas residuales.

Download or read book Water Availability and Management in Mexico written by Elena María Otazo-Sánchez and published by Springer Nature. This book was released on 2019-09-28 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents several complex case studies related to water management and planning in the context of pollution, growing demands, and global climate change in Mexico, but which are also relevant for other countries in Latin America. These concerns are of critical importance for policymakers who are coping with multiple conflicting interests. Water availability in Mexico is polarized, with abundant rainfall and large rivers in the south, and desert-like conditions in the north. The central region, which is the most industrialized, is overpopulated. Mexico City pours millions of cubic meters of “blackwater” into the northern valley daily and receives its clean water from the south. To address these unsustainable conditions, the world's 4th biggest water treatment plant went into operation in 2018. The water infrastructure and governance must satisfy the demands of all sectors, including agricultural, urban, and economic activities. At the same time, water resources are affected by drought, and climate change puts constraints on the supply. As such, regulation and monitoring are important when it comes to adherence to agreed plans and priorities. The book is divided into four sections. 1: Water Availability discusses quantitative aspects, such as supply, methods of calculation, and fracking. 2: Water Quality highlights pollution risks and diagnosis of water resources. 3: Water Allocation examines the sectoral demands and vulnerability due to unsustainable irrigation. 4: Water Governance and Management focuses on laws, urban rules, national parks, planning, and integrated water resources management, among other topics. The chapters include illustrative case studies in Mexico, such as basins, cities, reservoirs, and aquifers, water supply demand assessment, planning, and management.

Download or read book Tratamiento biol gico de aguas residuales principios modelaci n y dise o written by C. M. Lopez-Vazquez and published by IWA Publishing. This book was released on 2017-11-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: En las últimas decadas, el conocimiento y entendimiento del tratamiento de aguas residuales ha avanzado extensamente evolucionando de enfoques basados en procedimientos meramente empíricos a enfoques con principios básicos que abarcan la química, microbiología, física, ingeniería de procesos y matemáticas. La gran mayoría de estos avances han madurado a tal grado que han sido codificados en modelos matemáticos para su simulación en computadoras. Para una nueva generación de jóvenes científicos e ingenieros que ingresan al área del tratamiento de aguas residuales, la cantidad, complejidad y diversidad de estos nuevos desarrollos puede ser abrumador, particularmente en países en vías de desarrollo donde no existe un fácil acceso a cursos avanzados de postgrado en tratamientos de aguas residuales. Este libro tiene como objetivo resolver esta deficiencia ya que compila e integra el material de diversos cursos de postgrado de más de una docena de grupos de investigación de todo el mundo que han hecho contribuciones significativas para el desarrollo del tratamiento de aguas residuales. Cabe resaltar que la edición en inglés del presente libro, forma parte de un plan de estudios en tratamiento biológico de aguas residuales que incluye: • Resúmenes de las presentaciones y clases de los temas cubiertos en el libro • Videos de las clases de los profesores autores de los capítulos del libro • Ejercicios de auto-aprendizaje para los participantes en los cursos Al término del plan de estudios antes mencionado, los últimos avances en modelación y simulación de la operación y diseño de los sistemas de tratamiento de aguas residuales (ya sean lodos activados, procesos de remoción biológica de nitrógeno y fósforo, clarificadores secundarios o sistemas de biopelículas) pueden ser abordados con mayor profundidad, conocimientos más avanzados y mayor confianza.

This book was released on 2006-06-27 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, due to expanding populations and industries, regulatory authorities have imposed tighter discharge limits on nutrients from wastewater treatment facilities to avoid eutrophication in water streams. Common methods, such as metal salt precipitation, are being used to lower phosphorus concentrations which are a main contribution. However, alternate phosphorus removal techniques, such as phosphorus crystallisation, can provide further benefits. Precipitated solid can be utilised as a marketable fertiliser. Principles of magnesium and ammonia phosphate precipitation, working with a synthetic wastewater and a supernatant coming from dewatering an anaerobic digested sludge, are studied in this work. NOTE: This thesis is in Spanish.
