Download or read book Evaluaci n t cnica y econ mica de aspersores para riego por cobertura total written by Cristobal Antonio Sepúlveda Becerra and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: El estudio fue desarrollado en la parcela N°6 del sector Ñuble Alto, comuna de Chillán, VIII Región del Bio-Bio, Chile, durante los meses mayo a agosto de 2017. El objetivo fue realizar un análisis técnico - económico de aspersores bajo riego por cobertura total, basada en la uniformidad y gasto energético generado. La evaluación se realizó con una red de vasos graduados ubicados entorno a cada aspersor. Los datos de terreno se modelaron en Excel a diversos marcos, para calcular el Coeficiente de Uniformidad de Christiansen, el cual tenía que ser igual o mayor al 85%, proporcionar precipitación de 7 a 10 mm h-1 y la mínima presión posible, para ser seleccionado. El análisis de los aspersores se realizó considerando factores económicos que incorporó la vida útil de los aspersores y las tuberías requeridas. El aspersor que cumplió con las condiciones de borde, fue el NaanDanJain 5035 SD doble boquilla 5.0 mm y 2.5 mm (morada) a 3.5 bar, configuración de 18 x 18 m para una velocidad de viento de 5 km h-1, aspersor que si se compara con la condición actual del riego por cobertura total ( VYR-36 a una presión de trabajo de 3.0 bar), se otorga un ahorro por 2 hectárea de 2.8, 6.1 y 7.4 % para el recambio de aspersores y 6.5, 7.5 y 8.1% para proyectos nuevos que incluyen tuberías, para el valor mínimo, medio y máximo de combustible, respectivamente. Los resultados obtenidos muestran una relación proporcional entre consumo de combustible, presión y caudal. Los aspersores con doble boquilla, obtuvieron un buen Coeficiente de Uniformidad de Christiansen y Uniformidad de Distribución. Además, el marco óptimo, lo proporcionaron aspersores de doble boquilla. También, destacar que dentro de los costos totales de inversión en un sistema de riego por cobertura total, el costo de operación fue el más significativo

Available in PDF, EPUB and Kindle. Book excerpt: El presente Proyecto de Título surge de la práctica profesional realizada desde diciembre de 1993 a marzo de 1994 en el Depto. de Riego y Drenaje de la facultad de Ingeniería Agrícola, quien desarrollaba un proyecto de Evaluación del Sistema de Riego por Aspersión del Fundo San Isidro, propiedad de Sociedad Forestal Millalemu S.A. Se intenta hacer notar la importancia de una administración adecuada del agua particularmente sobre su mejor distribución y manejo. El objetivo de este estudio es definir el funcionamiento actual del sistema y analizar alternativas que permitan lograr un posible mejoramiento. El análisis considera principalmente la determinación de índices de eficiencia que definen el riego por aspersión dado. Se realizó una caracterización físico-hídrica y de relieve del suelo del vivero y la descripción del equipo de aspersión. Entre los resultados se obtuvo un Coeficiente de Uniformidad de Christiansen de 56,90 por ciento, para el funcionamiento actual del sistema. Si se consideran, además, los valores de otros índices obtenidos se concluye que efectivamente existen deficiencias en el manejo del sistema de riego. Una vez demostradas las eficiencias que existen se sugiere como principal cambio una nueva distribución de los aspersores en cuadrado 18x18 m, además de una serie de consideraciones de manejo, con lo cual se espera mejorar la eficiencia del riego y obtener un Coeficiente de Uniformidad cercano al 80 por ciento definido por la American Society of Agricultural Engineers (ASAE) como un estándar aceptable en riego agrícola.

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.

Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. 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.
