This book was released on 2017 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: La disponibilidad y calidad de las aguas se ha convertido en uno de los mayores problemas del sector industrial a nivel mundial. Por ello, en los últimos años se están realizando grandes esfuerzos en las industrias con el fin de alcanzar un uso sostenible del agua que incluya los nexos agua-energía-alimentación-salud. De esta forma se podrá desligar el crecimiento empresarial del uso excesivo del agua y del impacto ambiental causado por los vertidos industriales. Esta tendencia está motivada por una legislación cada vez más restrictiva en cuanto al consumo del agua y a la carga contaminante vertida al medio desde la industria, así como por una mayor concienciación medioambiental de la sociedad que mueve a las industrias a mejorar su imagen en materia de sostenibilidad. Además, en numerosas ocasiones, una gestión integral del agua permite ahorros económicos significativos. Para ello, se hace necesario el desarrollo de tecnologías más eficaces que permitan alcanzar los nuevos compromisos medioambientales objetivo de estas investigaciones. La industria alimentaria constituye uno de los sectores productivos más relevantes tanto a nivel europeo como nacional, siendo a su vez una de las actividades productivas con mayor consumo de agua y, por tanto, con mayor generación de aguas residuales. Las aguas residuales de este sector se caracterizan por su elevada carga orgánica, lo que implica que suelan ser tratadas mediante sistemas biológicos convencionales. Los tratamientos biológicos normalmente aplicados son aerobios, por su mayor facilidad de operación y de adaptación a cambios en las características del agua a tratar, dada la variabilidad de los procesos productivos del sector. Los tratamientos aerobios permiten alcanzar una calidad del efluente final apta para su vertido, pero cuando se tratan de aguas con altas cargas orgánicas los costes de operación, derivados principalmente de la necesidad de aireación del tanque aerobio y de la generación de fangos, son muy elevados a la vez que requieren reactores de grandes volúmenes...

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Este proyecto evalúa la utilización de la tecnología de membranas, ultrafiltración (UF) directa de agua del río Llobregat como pre-tratamiento a la osmosis inversa (OI) de la Estación de Tratamiento de Agua Potable (ETAP) de Sant Joan Despí, y como tratamiento alternativo a la actual etapa de clarificación (coagulación/floculación – sedimentación/decantación-filtros de arena) previa a la OI. Con la intención de optimizar el proceso de potabilización de agua en la ETAP y cumplir con una legislación de la calidad del agua cada vez más exigente, CETaqua (Centro Tecnológico del Agua) dentro del proyecto UFTEC (Substitution of conventional treatment of raw river water by ultrafiltration membrane technology) de tres años de duración, está evaluando filtrar agua directamente de río como alternativa a la actual etapa de clarificación, valorando las ventajas e inconvenientes que esto supondría. En concreto se estudia la tecnología de membrana mediante una planta piloto de dimensiones industriales, situada en la propia ETAP y de la cual se realiza un control de calidad del agua en varios puntos del proceso con la intención de valorar la eficacia de la planta comparando los resultados con los análisis que se realicen en el actual proceso de clarificación de la ETAP. Los análisis físico-químicos para la caracterización de las aguas del proceso de UF y de las aguas del proceso de clarificación, se llevan a cabo en la Plataforma Experimental de Membranas (PEM) situada en la misma ETAP, y en el caso de los análisis microbiológicos se realizan en el laboratorio de la Sociedad General de Aguas de Barcelona (SGAB). Tras esta primera fase experimental de cuatro meses del proyecto UFTEC (fase de estudio para este trabajo), se obtiene un agua de mayor calidad del agua producto mediante el sistema de membranas que en el proceso actual de clarificación, siendo óptima para su posterior utilización en la etapa de OI. A falta de la realización total del proyecto UFTEC, en el que se modificarán las condiciones de operación de la planta, y con la información que el presente proyecto nos proporciona, el futuro uso de la UF en el proceso de la ETAP de Sant Joan Despí, supondrá como beneficio, una reducción del espacio, disminución de la dosificación química, mayor rendimiento en la etapa de OI, menores costes en dicha etapa y por lo tanto del tratamiento global. Como desventaja en esta fase inicial se encuentra que la UF genera un volumen de efluente de rechazo superior al que se produce actualmente mediante el esquema convencional, hecho que se espera que mejore en el momento en que se inicie la fase de optimización de la operación de la UF.

Download or read book Anaerobic Digestion Model No 1 ADM1 written by IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes and published by IWA Publishing. This book was released on 2002-02-01 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.

Download or read book Applications of Activated Sludge Models written by Damir Brdjanovic and published by IWA Publishing. This book was released on 2015-02-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1982 the International Association on Water Pollution Research and Control (IAWPRC), as it was then called, established a Task Group on Mathematical Modelling for Design and Operation of Activated Sludge Processes. The aim of the Task Group was to create a common platform that could be used for the future development of models for COD and N removal with a minimum of complexity. As the collaborative result of the work of several modelling groups, the Activated Sludge Model No. 1 (ASM1) was published in 1987, exactly 25 years ago. The ASM1 can be considered as the reference model, since this model triggered the general acceptance of wastewater treatment modelling, first in the research community and later on also in practice. ASM1 has become a reference for many scientific and practical projects, and has been implemented (in some cases with modifications) in most of the commercial software available for modelling and simulation of plants for N removal. The models have grown more complex over the years, from ASM1, including N removal processes, to ASM2 (and its variations) including P removal processes, and ASM3 that corrects the deficiencies of ASM1 and is based on a metabolic approach to modelling. So far, ASM1 is the most widely applied. Applications of Activated Sludge Models has been prepared in celebration of 25 years of ASM1 and in tribute to the activated sludge modelling pioneer, the late Professor G.v.R. Marrais. It consists of a dozen of practical applications for ASM models to model development, plant optimization, extension, upgrade, retrofit and troubleshooting, carried out by the members of the Delft modelling group over the last two decades.

Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.
