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.

This book was released on 2017-09-27 with total page 242 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Water pollution problems are of continued importance around the world, with an impact on both populated areas and the environment. This volume consists of papers presented at the 14th International Conference in the series of Monitoring, Modelling and Management of Water Pollution. The environmental problems caused by the increase of pollutant loads discharged into natural water bodies requires the formation of a framework for regulation and control. This framework needs to be based on scientific results that relate pollutant discharge with changes in water quality. The results of these studies allow industry to apply more efficient methods of controlling and treating waste loads, and water authorities to enforce appropriate regulations regarding this matter. Environmental problems are essentially interdisciplinary. Engineers and scientists working in this field must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement, to name but a few. In view of the scarcity of available data, it is important that experiences are shared on an international basis. Thus, a continuous exchange of information between scientists from different countries is essential. Topics covered include: Water contamination; Monitoring, modelling and forecasting; Water management; Wastewater management; Groundwater and aquifers; Flood damage; Freshwater quality; Coastal and offshore pollution; Health risk studies; Agricultural contamination; Industrial pollution; Water reuse; Emerging technologies; Socio-economic-political consequences; Population and climate change; Education and training.

Book excerpt: Encompassing papers form the 2019 Water and Society Conference, this book is a collection of latest trans-disciplinary research on issues related to the nature of water, and its use and exploitation by society. This book demonstrates the need to bridge the gap between specialists in physical sciences, biology, environmental sciences and health. Over the centuries, civilisations have relied on the availability of clean and inexpensive water. This can no longer be taken for granted as the need for water continues to increase due to the pressure from growing global population demanding higher living standards. Agriculture and industry, major users of water, are at the same time those that contribute to its contamination. Water distribution networks in urban areas, as well as soiled water collection systems, present serious problems in response to a growing population as well as the need to maintain ageing infrastructures.Many technologically feasible solutions, such as desalination or pumping systems are energy demanding but, as costs rise, the techniques currently developed may need to be re-assessed. The research contained in this book addresses the interaction between water and energy systems.The socio-political implications of a world short of clean, easily available water are enormous. It will lead to realignments in international politics and the emergence of new centres of power in the world.The following list covers some of the subjects included in this book: Water resources management; Agribusiness; Water as a human right; Water quality; Water resources contamination; Sanitation and health; Water and disaster management; Policy and legislation; Future water demands; Irrigation and water management; Management of catchments; Groundwater management and conservation.
