Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse s'inscrit dans une problématique de modélisation et gestion des rejets en rivière, et plus particulièrement sur la façon dont les rejets se mélangent au sein d'une section perpendiculaire à l'écoulement. La prédiction de ce mélange est essentielle pour estimer les niveaux de concentration à l'aval des rejets et anticiper les impacts sanitaires et environnementaux. Elle se fait habituellement à l'aide d'un modèle simplifié qui suppose un écoulement uniforme longitudinalement (vitesse et profondeur constantes le long du cours d'eau), et introduit un coefficient dit « de mélange transverse », qui quantifie l'efficacité du mélange. Les études en rivière supposent l'uniformité longitudinale de l'écoulement, et rapportent des valeurs de ce coefficient souvent bien supérieures à celles en laboratoire pour lesquelles l'uniformité longitudinale de l'écoulement est vérifiée, et ce, sans explication plausible. L'objectif de cette thèse est de vérifier si le mélange transverse en rivière est accentué par un écoulement non-uniforme (accéléré ou décéléré) souvent observé sur le terrain, et non étudié en laboratoire. Pour répondre à cet objectif, des expériences de traçages in-situ ont eu lieu dans la Durance, une rivière de piémont présentant des écoulements non-uniformes longitudinalement. Une première campagne de mesure en rivière met en évidence une augmentation du coefficient de mélange transverse avec l'augmentation du paramètre de non-uniformité longitudinale de l'écoulement, aboutissant à une loi empirique permettant de prédire et d'expliquer les fortes valeurs du coefficient en rivières. Une deuxième campagne montre ensuite la forte influence de la résolution spatiale des mesures utilisées pour moyenner les paramètres hydrauliques du modèle simplifié, ainsi que le paramètre de non-uniformité. Enfin, une étude en conditions contrôlées de laboratoire, produisant des écoulement accélérés, confirme l'augmentation du coefficient de mélange transverse par rapport à un écoulement uniforme. Des expérimentations plus poussées restent cependant requises afin de comprendre les mécanismes associés à l'augmentation de l'efficacité du mélange en écoulement non uniforme, ainsi que pour établir une loi opérationnelle permettant de prédire le coefficient de mélange transverse dans une de rivière de piémont.

Book excerpt: La Directive Cadre sur l'Eau exige le retour au bon état des cours d'eau en Europe. Ces cours d'eau reçoivent en effet différentes pollutions liées aux différentes activités économiques des populations installées le long de leurs rives. On s'intéresse souvent de façon isolée à des types particuliers de pollution: pollution agricole dues aux pesticides, engrais et résidus d'élevage en milieu rural, pollution spécifique d'une industrie (sidérurgie, papeterie, etc.), pollution domestique plus ou moins bien traitée, etc. Or dans de nombreux cas, on a affaire à un mélange de polluants. Dans le cas de la Moselle, la pollution générée par les activités humaines dans la partie française du bassin versant de la Moselle impacte la qualité des eaux de surface en aval, et donc celle du Rhin. Notre but est de contribuer à caractériser l'état de certains affluents de la Moselle (Madon, Meurthe, Vologne et Fensch) en fonction de leurs pressions anthropiques et de proposer une stratégie pour calculer les flux des polluants le long de ces cours d'eau. Dans ce contexte des compagnes de prélèvement avec un pas spatial fin. Outre les paramètres habituels de caractérisation de l'état des masses d'eau (conductivité, pH, carbone organique dissous, azote ammoniacal, nitrates, etc.) une attention particulière a été portée aux propriétés optiques (absorbance UV-visible, fluorescence synchrone) de la matière organique dissoute afin de mieux comprendre son origine. Les spectres de fluorescence synchrone ont été étudiés par déconvolution ou par analyse en composantes principales. En outre une méthode a été développée, basée sur la spectroscopie de fluorescence synchrone, pour détecter la présence des azurants optiques. Enfin une méthodologie a été mise au point appliquée au Madon pour calculer les flux journaliers moyens de pollution à chaque station d'échantillonnage pour chaque période d'échantillonnage à partir de données géographiques. Cette méthode permet ensuite d'évaluer les flux de pollution.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.
