This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Existen diferentes programas que permiten realizar el diseño de sistemas de alcantarillados, UTOPÍA es un programa desarrollado por el Centro de Investigaciones en Acueductos y Alcantarillados de la Universidad de Los Andes (CIACUA). Este programa ha sido adaptado a diferentes ecuaciones de costo y de diseño, que tiene como propósito la optimización de la red a partir de la ruta más corta. metodología desarrollada por Bellman Ford. El programa no sólo busca minimizar los costos de la red, también debe cumplir con ciertas condiciones hidráulicas y de construcción, como los límites de excavación, relación de llenado de acuerdo con el diámetro de tubería, la velocidad mínima y la velocidad máxima. La investigación se centra en los efectos de modificar el límite de velocidad máxima, de acuerdo con los resultados, el diseño se ve afectado cuando en un terreno de alta pendiente (mayor al 8%) se restringe el límite de velocidad, ya aumenta de manera importante los límites de excavación, caso contrario en el que aumenta el límite de velocidad, en el cual se respetan los límites de excavación y se disminuyen los costos."--Tomado del Formato de Documento de Grado.

Book excerpt: "La presente investigación se pretende verificar el comportamiento de los diseños de redes de drenaje urbano, haciendo uso de la metodología desarrollada previamente por el CIACUA de la Universidad de los Andes, con la cual se encuentra la mejor alternativa de manera exhaustiva en materia de costos y aspectos constructivos. Permitiendo así, llevar a cabo diseños optimizados en un sistema de drenaje urbano que se caracterice por tener altas pendientes en el terreno, y que incluya el uso de cámaras de caída estándar como alternativa de optimización. Aunado con lo anterior, al contar con diseños óptimos, se genera sostenibilidad de estos sistemas que usualmente se ven afectados por las altas fuerzas abrasivas del flujo que conducen y evitando sobrecargas que afecten a las poblaciones. Siendo lo anterior congruente con lo expuesto por la Ingeniera Andrea Marú en su trabajo publicado en el 2018, denominado como Diseño optimizado de tuberías en serie en sistemas de alcantarillado incluyendo estructuras de caída; con el cual fue propuesto un cambio a la metodología propuesta por Natalia Duque en el 2013, la cual consiste en la inclusión del módulo de cámaras de caída al programa de diseño óptimo para series de tuberías, el cual pertenece al CIACUA. Así las cosas, con la inclusión de cámaras de caída según sean requeridas en el marco del cumplimiento de las restricciones hidráulicas tales como velocidad máxima, se generan escenarios factibles de menor costo que aquellos donde no se tenga la posibilidad de crear cámaras de caída y la red deba profundizar en aras de cumplir con las restricciones de velocidad propuestas."--Tomado del Formato de Documento de Grado.
Download or read book Relaci n l mite entre criterios de autolimpieza y dise o optimizado de alcantarillados como funci n del caudal y la pendiente written by Sebastián González Hernández and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "En un principio los sistemas de alcantarillado fueron concebidos como estructuras hidráulicas que permitieran la evacuación rápida de las aguas grises y negras sin tener en cuenta el posible impacto en el cuerpo receptor. Con el paso del tiempo está idea se fue modificando y hoy en día los alcantarillados se ven de forma integral tomando en cuenta todas las partes involucradas. El sistema de drenaje se divide en tres grandes partes: la red de drenaje urbano (objeto de la investigación), la planta de tratamiento (no siempre necesaria) y el cuerpo receptor. Al estudiar y diseñar el sistema de drenaje como un complemento de las tres partes mencionadas se garantiza el buen funcionamiento y la armonía del sistema integrado permitiendo una evacuación ya no únicamente rápida sino segura tanto para las personas como para el medio ambiente. El presente documento busca encontrar el límite donde la restricción de autolimpieza no afecte el diseño optimizado del alcantarillado (límite superior), es decir el límite donde sin importar cuál de los criterios de autolimpieza se escoja el costo final del diseño optimizado del alcantarillado es el mismo. Lo anterior se evalúa para diferentes pendientes del terreno teniendo en cuenta criterios tradicionales y el criterio recomendado por la Sociedad Americana de Ingenieros Civiles denominado Tractive Force el que por medio de una ecuación, conociendo pocas características de los sedimentos, permite encontrar el esfuerzo cortante mínimo. Adicional al límite mencionado también se encuentra el mínimo caudal que permite un diseño factible para cada uno de los criterios autolimpieza al cambiar la pendiente promedio del terreno (límite inferior). Lo anterior permite establecer un rango de pendientes del terreno y caudales a partir de los que cada restricción puede ser utilizada."--Tomado del Formato de Documento de Grado.

This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

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.

This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
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.
