Book Description
Ce travail s'inscrit dans un contexte général qui concerne les procédés de Séparation Liquide Solide (SLS) et plus particulièrement : la filtration/compression et le séchage. L'objectif de ce travail est de modéliser ces deux procédés en tenant compte du comportement mécanique du produit étudié. Dans la première partie du travail, une caractérisation expérimentale des argiles utilisées (kaolin et bentonite), en rapport avec le séchage, est présentée. Dans un deuxième temps, un modèle thermo-hydro-mécanique général est développé. Le modèle est ensuite testé dans deux situations différentes : unidirectionnelle et bidirectionnelle. La deuxième partie de l'étude est consacrée à l'étude et la modélisation des procédés de filtration/compression. Le modèle développé dans ce travail décrit uniquement la phase de compression, et tente, comme précédemment, de fournir un modèle hydromécanique. Des simulations issues de la résolution numérique du modèle, permettent en partie de valider la démarche entreprise.

Book Description
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.

Book Description
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.

Book Description
This successful text/reference, now in a new edition, explores the applications and limitations of data produced by the interaction of X-rays with clay minerals. This edition pays particular attention to integrating the mineralogy of soils and features a new chapter on disorder and polytypes. Chapter Four, from the first edition, has been expanded and split into two chapters, "Structure and Properties: General Treatment" and "Structure, Nonmenclature, and Occurrences of Clay Minerals." Essential in agriculture, geology, and in making informed engineering decisions, this text offers the necessary information on the properties of these minerals, combining theoretical discussion with recipe-like directions for laboratory procedures. Ideal for students who have completed introductory geology, chemistry, and mineralogy courses, this text can also be used as a reference for researchers and workers in industry.

Book Description
New methods for the determination of the nature, proportion, and distribution of structural defects in microcrystallized lamellar systems are of utmost importance not only to experimentalists but also to theoreticians. Mathematical formalism - indispensable for such analyses - is well-illustrated by various examples, allowing this method to be easily adopted and even to be applied to other solids with lamellar or pseudo-lamellar structures.
