Sludge Management provides up-to-date information on sludge treatment, reuse and disposal. A comprehensive coverage of all issues related to sludge management is included with local through global coverage of all sludge management practices. Conventional to advanced technologies for sludge management with available case studies from both developing and developed countries are covered in this book. Given the responsibility of engineers to develop the technological tools to meet the increasingly stricter standards for sludge treatment and disposal, the main attraction of the book principally relies on its technical content that reviews all the points to be considered in sludge management from engineering and technological perspectives. Sludge Management can be used for planning, designing, and implementing waste sludge management projects. Moreover, this book can be used as a standard textbook in Universities for Master and Doctoral students. Also, academics, researchers, scientists, and practicing engineers working in the field of sludge management would find the book very informative and a source of interesting case studies.

Sustainable Development has become the leading concept of the 21 century. It describes a development, which agrees with the needs of the present generation but does not endanger the chances of the coming generations to satisfy also their needs. "Sustainable development" has become an important general goal for all fields of life like economy, ecology and social balance. The development and shaping of our future has been discussed internationally like on the summits of the Conferences in Rio and in Johannesburg. But this is also a topic on national base in various countries. Leading authorities in various fields of economy and politics have also accepted this concept. Although the concept of sustainable development has been generally accepted, there are still problems how to achieve and evaluate these general goals. It is clear that the definitions about the prime needs vary from man to man, from country to country and from continent to continent. But pollution does not respect national borders. Therefore, it is necessary to develop the politics of economy, ecology and social demands by a synergistic way that they are strengthened by each other. If it is not possible to stop tendencies, which threaten the future quality of life, the cost demands of societies will dramatically increase and negative tendencies will become irreversible.

A sine qua non of control system development for modern sewer networks is the preservation of the water system around a network 's outflow(s). Several approaches have been proposed for the optimisation of sewage control and Optimal Real-time Control of Sewer Networks provides a comparative synthesis of a central sewer network flow control based on two of these: nonlinear-optimal and multivariable-feedback control.

Testing and comparison of these protocols are made on the basis of their control results for the large-scale sewer network located around the river Obere Iller in Bavaria. The control strategies implemented within this network are based on this study.

From the selection of possible methods of control and moving to the implementation of those methods in a real sewer system, this monograph will be invaluable to control and civil engineers working in sewage flow and wastewater treatment and of interest to academics wishing to see how their ideas on optimal control work out when practically applied.

This book offers a comprehensive review of how plastic pollution is affecting fresh and marine waters, and what the current challenges in plastic waste assessment and management in the aquatic environment are. Plastic waste comprises particles with heterogeneous physicochemical properties such as large size-range, different shapes and polymer types with various additives determining their environmental fate and risk. This complexity raises several open research questions which are explored in this book. Examples are the plastic uptake by aquatic organisms, degradation processes as well as sources and sinks in the environment. Readers will discover real case studies of plastic pollution detection and management in different parts of the world, including Asia, America and Europe, which provide an integrated overview of the global scope of this issue. This book and the companion volume Plastics in the Aquatic Environment - Part II: Stakeholders' Role Against Pollution are valuable resources to students, researchers, policymakers and environmental managers interested in plastic pollution and working towards its reduction.

This book arises from a 2011 international conference entitled Climate Change, Agri-Food, Fisheries and Ecosystems: Reinventing Research, Innovation, and Policy Agendas for an Environmentally and Socially-Balanced Growth (ICCAFFE2011), organized by the North-South Center for Social Sciences (NRCS) in collaboration with the Deutsche Gesellschaft fur Internationale Zusammenarbeit (GIZ) GmbH, Germany and the Institute for Research and Development (IRD), France. Coverage focuses on the agricultural sector and helps improve understanding of the relationships between agriculture and the environment and between human communities and nature, so as to sustainably manage agricultural development. The contributors analyze the interdependence between sustainable agricultural development and environmental, economic and social dynamics; assess the impacts of soil degradation on agricultural productivity; present ways to enhance livestock production and recommend mechanisms for managing links between agro-biodiversity, climate change and livelihoods. Part I examines sustainable agriculture development and environmental, economic and social dynamics, addressing topics such as global climate change, agriculture and challenges including socio-economic factors, adaptation, poverty reduction and water management. Part II covers the impacts of soil degradation on agricultural productivity and discusses the use of expert systems to assess and manage degraded lands, agricultural productivity, land suitability and rehabilitation. Part III focuses on livestock production enhancements, such as feed resources and supplemental feeds for animals and capacity building for women in dairy management. Part IV shares the outcomes of research in agro-biodiversity, climate change and livelihoods, addressing topics such as co-management of forests, carbon consumption models, biodiversity conservation and carbon sequestration and scarce mangrove forests. Current environmental and agro-ecological research focuses on understanding the cause-consequence relationships between specific agricultural practices and land use and the responses at different levels of ecosystems. This book is intended to contribute to this discussion."

As urban areas keep growing, water infrastructure ages, and the requirements on environmental protection become more rigorous, there is a continual need for upgrading water pollution control facilities and restoring degraded urban waters. Such issues are addressed in this book by focusing on five major topics: (a) Upgrading stormwater management facilities, (b) Retrofitting / upgrading combined sewer overflow (CSO) facilities, (c) Optimising/upgrading sewage treatment plant performance, (d) Urban stream restoration, and (e) Challenges in restoring urban environment. Each chapter contains some overview papers followed by research or case study papers. Besides presentations of new approaches and accomplishments in the field of upgrading and restoration, several papers provide analysis of vast needs in this field in several countries of Central and Eastern Europe, which either recently joined the European Union (EU) or are preparing for accession, and need to comply with the existing EU directives dealing with environmental protection. As such, this book will be of primary interest to researchers and university lecturers dealing with environmental upgrading and restoration, environmental planners from all levels of government, municipal engineers and politicians, and finally the private industry representatives (consultants, private utilities and environmental technology suppliers) searching for new business opportunities among the new or aspiring members of EU.

The protection of groundwater and surface water from contamination by the escape of contaminant from waste disposal is now an important consideration in many countries of the world. This book deals with the design of 'barrier systems' which separate waste from the surrounding environment and which are intended to prevent contamination of both groundwater and surface waters. The authors discuss all key aspects of the design of barrier systems, including leachate collection, natural barriers such as clayey aquitards, clay liners, geomembrane and composite liners, providing a state-of-the-art work of reference of great value to engineers and environmentalists alike. This retitled second edition of Clayey Barrier Systems for Waste Disposal has been fully revised and updated, with new chapters on geomembranes and geosynthetic clay liners as well as a number of new chapters. Engineers involved with waste management, geotechnics and landfill design will use this book in order to understand the concepts, find out about the latest developments and subsequently apply them to practical applications relevant to the design of barrier systems.

Dealing with stormwater runoff in urban areas is a problem that is getting bigger and more expensive. As we cover porous surfaces with impervious structures-commercial buildings, parking lots, roads, and houses-finding places for rainwater and snowmelt to soak in becomes harder. Many landscapers, architects, planners, and others have proposed that the use of "green" localized management practices, such as rain gardens and bio-swales, may function as well as traditional "gray" pipes and basins at reducing the effects of stormwater runoff, and do so in a way that is more attractive in the landscape-and possibly also less expensive. To make stormwater management practices work, however, communities need to know the real costs and policy makers need to give people incentives to adopt the best practices. Economic Incentives for Stormwater Control addresses the true costs and benefits of stormwater management practices (SMPs) and examines the incentives that can be used to encourage their adoption. Highlighting the economic aspects, this practical book offers case studies of the application of various stormwater runoff control policies. It also presents the theory behind the different mechanisms used and illustrates successes and potential obstacles to implementation. The book covers: Efficient use of "green" SMPs Low-impact development (LID) style new construction Green infrastructure Property prices and incentive mechanisms to encourage homeowners to retain stormwater on their property Legal, economic, and hydrological issues associated with various incentive mechanisms In-lieu fees and cap-and-trade incentives Primarily concerned with the sociodemographic and economic aspects of people's participation in stormwater runoff control, this accessi

In the past decade there has been a rapid increase in waterborne outbreaks of disease associated with viral and protozoan agents, normally in drinking waters that were found to be microbially safe using the Coliform Index. For nearly a quarter of a century indicator organisms, in particular the coliform group, have been used to ensure the microbial quality of drinking water. Currently, world wide legislation to protect consumers is based on these outdated and unreliable tests and while there is considerable concern among scientists over their use, the water industry and regulators continue to place near total reliance on the Coliform Index. This book provides: * the first full account of the nature and applications of the Coliform Index * coverage of new and proposed water quality legislation: * details of emerging pathogens in water: * an evaluation of the role of the "coliform count" in future water quality analysis. It will be an essential tool for water companies at all levels, microbiologists, environmental health inspectors, environmental scientists and water engineers in industry whether working in developed countries or developing countries. Postgraduate students specialising in microbiology, civil and environmental engineering, environmental sciences and environmental health will find it a useful reference work as will undergraduates in these disciplines.

Sewer systems fall into the category "out of sight, out of mind" - they seldom excite interest. But when things go wrong with the air in the sewer system, they go very wrong. Consequences can be dramatic and devastating: sewer workers killed instantly by poisonous gas when they lift a sewer lid, or entire suburban blocks levelled by explosions. This book describes the atmospheric dangers commonly found in the sewer system. It provides easily-understood explanations of the science behind the hazards, combined with real-life examples of when things went dramatically wrong.

Vadose Zone Hydrology describes the elements of the physical processes most often encountered by hydrogeologists and ground-water engineers in their vadose zone projects. It illustrates the application of soil physics to practical problems relevant to the characterization and monitoring of the vadose zone. It includes an introduction to physical processes, including basic flow theory, and provides examples of important field-scale processes that must be recognizable by hydrogeologists. Considerable attention is given to the concepts of recharge, including how it is most accurately evaluated in the vadose zone. Field and laboratory methods for characterizing hydraulic properties in the vadose zone are also covered, and case studies illustrating these methods are provided. New and emerging technologies for monitoring the vadose zone, particularly for the purpose of detecting contaminants, are highlighted. In the last section of the book, additional case studies are presented, demonstrating applications related to seepage detection, landfill monitoring, and soil gas investigations. This book is written from the perspective of hydrogeologists and is designed to be directly applicable and to maintain continuity and consistency between chapters. It will be an invaluable primer for environmental or geotechnical consultants, regulators, or students who have no prior formal academic training in unsaturated flow concepts. Because the text contains some of the latest advances in this field, it will be an excellent reference for geologists and engineers currently working on problems of vadose zone hydrology.

This book provides a concise synthesis of how toxic chemical pollutants affect physiological processes in teleost fish. This Second Edition of the well-received Water Pollution and Fish Physiology has been completely updated, and chapters have been added on immunology and acid toxicity. The emphasis, as in the first edition, is on understanding mechanisms of sublethal effects on fish and their responses to these environmental stressors. The first chapter covers the basic principles involved in understanding how fish respond, in general, to environmental alterations. Each subsequent chapter is devoted to a particular organ system or physiological function and begins with a short overview of normal physiology of that system/function. This is followed by a review of how various toxic chemicals may alter normal conditions in fish. Chapters covering environmental hypoxia, behavior, cellular enzymes, and acid toxicity are also included. The book closes with a discussion on the practical application of physiological and biochemical measurements of fish in water pollution control in research and regulatory settings.
