Wastewater Recycling Reuse And Reclamation Vol I

Total supply of fresh water on earth far exceeds human demand. However, scarcity of water currently faced in many regions of the world is caused by two reasons. First, its availability in time and space is not equally distributed. Thus there is problem of water in the wrong place, or at the wrong time and in wrong quantities. Second, while the population growth and expanded industrial activities are increasing demands on available water resources, they also jeopardize the availability of freshwater in adequate quantities by discharge of pollutants into freshwater sources. It is at times like these, when the rising curve of water demand intersects the fluctuating curve of water availability, recycle and reuse of wastewater is seriously considered. Wastewater recycling, reuse and reclamation have been, now, accepted as appropriate ways to conserve water resources as well as to contain polluted waters from contaminating other available clean water sources. This book gives a comprehensive review on water quantity and quality, simple water supply and sanitation systems, and leads to domestic, agricultural and industrial water reuse. Thus, it will provide useful information not only to technologists but also for planners, managers, and NGOs involved in the water sector. The contribution to the book comes from a broad pool of experts, working on technology, policy, health, and economy aspects of water management. Involvement of both academics and industry personnel from developing and developed countries makes this contribution broader and useable for a wide readership.

The effective integration of water and reclaimed wastewater still requires close examination of public health issues, infrastructure and facilities planning, wastewater treatment plant siting, treatment process reliability, economic and financial analyses, and water utility management. This book assembles, analyzes, and reviews the various aspects of wastewater reclamation, recycling, and reuse in most parts of the world. It considers the effective integration of water and reclaimed wastewater, public health issues, infrastructure and facilities planning, waste-water treatment plant siting, treatment process reliability, economic and financial analysis, and water utility management.

This issue contains a selection of 43 papers presented at the 3rd International Symposium in Paris. Several papers from Asia and Europe offer national experiences and perspectives on water reuse. Project planning problems, pitfalls and keys to success are discussed through examples from Australia, the United States and Europe. Wastewater reuse is acknowledged as a basic component of integrated water resources management, and its environmental impact is taken into account in economic evaluations.

This comprehensive reference provides thorough coverage of water and wastewater reclamation and reuse. It begins with an introductory chapter covering the fundamentals, basic principles, and concepts. Next, drinking water and treated wastewater criteria, guidelines, and standards for the United States, Europe and the World Health Organization (WHO) are presented. Chapter 3 provides the physical, chemical, biological, and bacteriological characteristics, as well as the radioactive and rheological properties, of water and wastewater. The next chapter discusses the health aspects and removal treatment processes of microbial, chemical, and radiological constituents found in reclaimed wastewater. Chapter 5 discusses the various wastewater treatment processes and sludge treatment and disposal. Risk assessment is covered in chapter 6. The next three chapters cover the economics, monitoring (sampling and analysis), and legal aspects of wastewater reclamation and reuse. This practical handbook also presents real-world case studies, as well as sources of information for research, potential sources for research funds, and information on current research projects. Each chapter includes an introduction, end-of-chapter problems, and references, making this comprehensive text/reference useful to both students and professionals.

Milestones in Water Reuse: The Best Success Stories illustrates the benefits of water reuse in integrated water resources management and its role for water cycle management, climate change adaptation and water in the cities of the future. Selected case studies are used to illustrate the different types of water reuse, i.e. agricultural irrigation, golf course and landscape irrigation, urban and industrial uses, environmental enhancement, as well as indirect and direct potable reuse. The various aspects related to water reuse are covered, including treatment technologies, water quality, economics, public acceptance, benefits, keys for success and main constraints. These international case studies highlight the best practices for the implementation of water reuse and provide the perspective for the integration of water recycling projects in the future, both for megacities and rural areas. Milestones in Water Reuse: The Best Success Stories demonstrates that planned water reuse is a cost competitive and energy-saving option to increase water availability and reliability. This book provides policy makers and regulators with a good understanding of water reuse and helps them to consider recycled water as safe and how it can be used. It is intended to be read by all people in the water sector and shows how water reuse is safe, economically viable, environmentally friendly and can provide high social benefits.
