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.
Dr. S. Vigneswaran is currently a Professor and a Head of Environmental Engineering Group in Faculty of Engineering, University of Technology, Sydney, Australia. He has been working on water and wastewater research since 1976. He has published over 175 technical papers and authored two books (both through CRC press, USA). He has established research links with the leading laboratories in France, Korea, Thailand, and the USA. Also, he has been involved in number of consulting activities in this field in Australia, Indonesia, France, Korea and Thailand through various national and international agencies. Presently, he is coordinating the university key research strengths on “water and waste management in small communities,” one of the six key research centers funded by the university on competitive basis. His research in solid liquid separation processes in water and wastewater treatment namely filtration, adsorption is recognized internationally and widely referred
