Book excerpt: This work describes the sewer system as an integrated part of the wastewater treatment system. The main objectives of this study were: identification and quantification of water sources collected in sewer system, referring to isotopic signatures of water and dissolved sulfates; identification of the mineralogical nature of trace element carriers and determination of their geochemical evolution within the sewer by TEM and SEM coupled with EDSX ; Evidencing exchanges between sewage and biofilms, using CLSM and TEM, and investigating hydrodynamic conditions controlling this exchange in an experimental set-up (Couette-Poiseuille reactor). The results indicate that isotopic data may be used to study the tightness of sewer lines and to evaluate the evolution of element concentrations along sewer. Implication of the sewer system as a true biophysicochemical reactor is evidenced in our study by the evolution of the mineralogical nature of phosphate phases downstream of the sewer and by heavy metal precipitations in anaerobic conditions as neoformed sulfide phases. Sump pit deposits and biofilms represent the earlier stage of this neoformation. Organic matter biodegradation was revealed by TEM examination of SM whereas the exchange between biofilms and SM was shown by CLSM. Cellulose fibers from SM were found embedded in exopolymer biofilm matrices and detached fragments from biofilms were identified in sewage. The majority of these evolutions are located upstream of sewer system in which the contrast in physicochemical properties are the most significant. Finally, biofilm model investigations and image processing showed that hydrodynamic conditions are largely implicated in biofilm detachment.

This book was released on 2001 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les exigences de la législation sur l'eau et les déchets auront pour conséquence, une augmentation de la production de boues associée à des contraintes croissantes d'évacuation. Aussi, l'étude de procédés contribuant à une réduction de la production de boues tout en préservant la qualité de l'épuration de l'influent devient une priorité. Dans un premier temps, la production de boues d'un système biologique conventionnel a été étudiée. Un modèle mathématique a été appliqué afin de décrire et de quantifier par une étude de sensibilité du modèle, les paramètres déterminants de la production de boues tels que le rendement de conversion, le taux de décès et la fraction inerte. L'étude des différents traitements physico-chimiques a permis l'évaluation des potentialités spécifiques tant vis à vis de la réduction de la taille des particules, favorable à une augmentation de la biodégradabilité que, vis à vis d'une inactivation des cellules, synonyme d'une augmentation des besoins de maintenance et/ou du décès cellulaire et/ou de la lyse cellulaire. L'étude et l'identification de la synergie des processus physico-chimiques et biologiques de transformation de la matière organique et minérale est réalisée à partir d'essais en continu. L'analyse partielle des mécanismes d'action des traitements associés a été réalisée à partir des essais en discontinu et continu. Une réduction significative de la production de boues ne semble envisageable que, si le traitement associé induit une augmentation des besoins de maintenance des cellules, une augmentation de la biodégradabilité de la pollution accumulée dans le système lors du procédé d'épuration. Basée sur les performances des systèmes en terme de réduction de la production de boues et sur les mécanismes d'action, une première comparaison des technologies de traitements associés est réalisée. Le suivi de la qualité de et des boues produites permet de valider l'intégration de tels procédés dans la filière de traitement des eaux usées.

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.

Book excerpt: Urban Drainage: A Multilingual Glossary has been written by research engineers and scientists with substantial experience in the urban drainage field. It provides definitive descriptions of urban drainage terms in English, French, Japanese and German, giving guidance on their appropriate usage and context. The glossary also contains many diagrams, tables and technical discussions, and is a very practical tool to facilitate international technical communication in the urban drainage field. Containing well over 850 commonly-used terms in urban drainage, all expressed in a user-friendly manner, the book serves as a valuable resource for both practitioner and academic. Topics covered include: urban hydrology/hydraulics sewerage surface water runoff pollution (groundwater and surface) receiving waters ecology ecotoxicology best management practices urban water resource management Urban Drainage: A Multilingual Glossary represents an initiative of the joint IWA/IAHR Committee on Urban Drainage and has arisen out of the long-standing terminological and tautological difficulties of many terms in common usage within international urban drainage practice. It will be of great use and interest to scientists, engineers and ecologists, professionals and students working in urban hydrology/hydraulics, urban water resource management and regulation, urban planning and ecology.

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.

Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects

Book excerpt: This popular, often cited text returns in a softcover edition to provide a thorough introduction to statistical physics and thermodynamics, and to exhibit the universal chain of ideas leading from the laws of microphysics to the macroscopic behaviour of matter. A wide range of applications illustrates the concepts, and many exercises reinforce understanding. Volume II applies statistical methods to systems governed by quantum effects, in particular to solid state physics, explaining properties due to the crystal structure or to the lattice excitations or to the electrons. The last chapters are devoted to non-equilibrium processes and to kinetic equations, with many applications included.
