Water Supply and Sanitation

Water scarcity and sanitation are two major challenges that are affecting over 40% of the global population. More than 80% of the waste water resulting from human activities is dumped in rivers or the sea without any kind of water treatment. To respond to this crucial need, appropriate technologies of water treatment and supply are discussed in this book. A unique feature of this book is the way in which chapters interact. Cross-references between theory and application foster overall integration of subject matter. This volume will assist process engineers, water treatment plant operators and managers, environmental consultants, water treatment plant operators, U.G. and P.G. students of civil, environmental and chemical engineering. Recommendations of various Indian Standards pertaining to the subject including Water Manual by Central Public Health and Environmental Engineering under Ministry of Urban Development has been incorporated and followed. All the chapters are organised with definitions, design principles and theories.
