Download or read book Water Reuse written by Chris Binnie and published by IWA Publishing. This book was released on 2008-05-14 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differently wastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater. In the first section water reuse practices around the world are described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view. Each reuse purpose demands different water quality, not only to protect health and the environment but also to fulfil the requirements of the specific reuse. Reuses considered are agricultural, urban agriculture as a special case of the former, municipal and industrial. Alongside these uses, the indirect reuse for human consumption through aquifer recharge is also discussed. The third section deals with emerging and controversial topics. Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as the different international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered. The fourth section of the book presents contrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse. Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for human consumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for regulating water reuse in several countries, the Mediterranean situation is described. Other case studies presented refer to the reuse situation in Israel, Spain, Cameroon, Nepal and Vietnam, these latter countries being located in water rich areas. This book will be an invaluable information source for all those concerned with water reuse including water utility managers, wastewater policy makers and water resources planners as well as researchers and students in environmental engineering, water resources planning and sanitary engineering.

Download or read book Water Reuse written by National Research Council and published by National Academies Press. This book was released on 2012-07-17 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

Download or read book Wastewater Recycling Reuse and Reclamation Vol I written by Saravanamuthu Vigneswaran and published by EOLSS Publications. This book was released on 2009-11-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2017-06-15 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.

Available in PDF, EPUB and Kindle. Book excerpt: Affordable and effective domestic wastewater treatment is a critical issue in public health and disease prevention around the world, particularly so in developing countries which often lack the financial and technical resources necessary for proper treatment facilities. This practical guide provides state-of-the-art coverage of methods for domestic wastewater treatment and provides a foundation to the practical design of wastewater treatment and re-use systems. The emphasis is on low-cost, low-energy, low-maintenance, high-performance 'natural' systems that contribute to environmental sustainability by producing effluents that can be safely and profitably used in agriculture for crop irrigation and/or in aquaculture, for fish and aquatic vegetable pond fertilization. Modern design methodologies, with worked design examples, are described for waste stabilization ponds, wastewater storage and treatment reservoirs; constructed wetlands, upflow anaerobic sludge blanket reactors, biofilters, aerated lagoons and oxidation ditches. This book is essential reading for engineers, academics and upper-level and graduate students in engineering, wastewater management and public health, and others interested in sustainable and cost-effective technologies for reducing wastewater-related diseases and environmental damage.
Download or read book World Sustainable Development Outlook 2007 written by Allam Ahmed and published by Routledge. This book was released on 2017-09-29 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The World Sustainable Development Outlook series has been developed to provide an overview of sustainable development, to discuss why it is important and to provoke forward thinking on the development of a more coherent approach to solving global problems related to sustainability through science and technology. In doing so, a holistic approach is used to critically examine the interrelationship between the natural, governmental, economic and social dimensions of our world and how science and technology can contribute to solutions. This is a truly global source book, which is reflected in the varied national and cultural origins of the contributors, as well as the topics and case studies covered. Each year a different theme will be covered. The theme of World Sustainable Development Outlook 2007 is the different dimensions of knowledge and technology management in the new era of information revolution and how they relate to sustainable development. Rapid innovation in information and communication technologies (ICTs) is clearly reshaping the world we live in. Countries are increasingly judged by whether they are information-rich or information-poor. It is estimated that 30–40% of the world's economic growth and 40–50% of all new jobs will be IT-driven. Education and knowledge are the chief currencies of the modern age, and can also be a strategic resource and a lifeline for sustainable development. Yet, in Africa, millions of people have never made a telephone call. The technological gulf between developed and developing countries (DCs) is likely to widen further with the rapid expansion of the internet and the speedy transition to digitalisation in the West. The impacts on DCs may include an increase in the so-called brain drain and growing dependence on foreign aid of a different kind – knowledge aid. There are fears that knowledge imperialism is already with us. What is clear is that most of the technological innovations in ICTs are Western-designed and fail to address the needs of the most disadvantaged. The interest of industrialised countries in the use of ICTs in DCs has largely been more concerned with the profitability of their own business enterprises than with any broader goals concerning the development of the host countries. DCs face the challenge of either becoming an integral part of the knowledge-based global economy or the very real danger of finding themselves on the wrong side of the digital divide. Successful management in the new millennium requires developing new methods and approaches to meet the challenges and opportunities of this information revolution while at the same time fostering sustainable development. Adopting a holistic approach, this book aims to critically examine the interrelationship between these different issues in order to reach solutions and a consensus for a better future, taking into account a variety of international, institutional and intellectual perspectives. It uses case and country studies in technological innovation and experience so that lessons in effective management of ICTs can be learned from successful initiatives, ideas and innovations.
