Over the past 50 years the volume of wastewater has grown exponentially as a result of the increasing world population and the expansion of industrial developments. Researchers all over the world have been trying to address this issue suitably in order to fight water scarcity; yet, it is only recently that wastewater recycling has caught their attention as an effective and responsible solution. Wastewater is a resource that can be adequately treated to successfully satisfy most water demands as well as decreasing wastewater discharges and preventing pollution. This book presents the studies of some of the most prestigious international scientists and gathers them in three different sections: Wastewater Management and Reuse, Wastewater Treatment options and Risk Assessment. The result is an insightful analysis of waste water management, its treatments, and the processes that have been studied, optimized and developed so far to sustain our environment. Wastewater Reuse and Management represents a valuable resource to academic researchers, students, institutions, environmentalists, and anyone interested in environmental policies aimed at safeguarding both the quality and the quantity of water.

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.

Over time, the increased use of fresh water for agriculture and industry together with contamination from discharges of pollutants, mean that ever more areas of the planet are becoming water-stressed. Because of the competing needs of communities and industry for fresh water, industry will be challenged to meet its growing demands for water, which is essential for producing the goods and services that would boost human welfare. Thus industry will need to learn how to cost-effectively purify and recycle its wastewater for reuse, ultimately approaching a net zero-discharge condition. The chapters in this book, written by international experts, treat the technical issues of such treatment and water management, and also provide guidance on technologies, either existing or in development, that can potentially achieve the goal of recycle-reuse. The book will serve as a useful reference for academics, government and industry professionals alike.

This text is a how-to guide on cutting water usage in industrial operations, with practical guidance and four examples from diverse industries: aluminium smelting; a paper mill; electric powder generation; and transportation equipment manufacturing.

This publication presents the lectures given at the course on Advanced Separation Technology for Industrial Waste Minimization: Environmental and Analytical Aspects (13-15 October, 1992, Ispra, Italy) organized jointly by the Technical University of Lisbon, University of Calabria and the Environment Institute of the Joint Research Centre of the Commission of the European Communities at Ispra. This course is integrated in a programme for education and training in Advanced Separation Technology for Industrial Waste Minimization supported by the Community Action Programme for Education and Training for Technology (COMETT II). The lecture material is based on case studies of importance to textile, tanneries, pulp and paper, metal finishing and electroplating, food, and other industries. Environmental regulations have lead industrial engineers to search for more efficient, less energy consuming and less waste producing processes. Membrane-based separation processes contributed to recover water, raw materials and energy and to achieve simultaneously pollution control. Along this book emphasis will be given to this fast growing area of process technology.

Money-saving water strategies for industry.In the U.S. alone, process industries, petrochemicals, pulp and paper, metals and minerals, and many others ù will generate over 120 million tons of wastewater by the year 2000. Industrial Water Reuse and Wastewater Minimization, by James G. Mann and Y.A. Liu, describes water reuse and wastewater minimization principles and practices thatcan be used worldwide. Relatively easy to use and surprisingly inexpensive, the methods youÆll find in this important guide - particularly water-pinch technology ù are not only ecologically sound, but significantly lower manufacturing costs. Concepts are illustrated withabundant charts, tables, and real-life case studies.This resource includes a CD-ROM at no additional cost. Its Water/Target software generates freshwater use/wastewater generation targets, and suggests ways to reach them....lets you isolate bottlenecks limiting water reuse and find new reuse opportunities - all without the expense ofdetailed.

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.
