Chittaranjan Ray, Professor of Civil & Environmental Engineering and Interim Director of the Water Resources Research Center at the University of Hawaiʻi at Mānoa, co-edited a new book entitled “Drinking Water Treatment: Focusing on Appropriate Technology and Sustainability” with Ravi Jain, Dean of Engineering and Computer Science at the University of the Pacific.
Published by Springer, this 262-page book focuses on four treatment technologies, namely solar pasteurization, membrane desalination, riverbank filtration as a natural filtration method, and solar distillation for drinking water production.
The book begins with a comparative analysis of various water treatment technologies and subsequently addresses the details of the four treatment techniques. Finally, it provides a trans-disciplinary analysis of differing views of the concept of sustainability and highlights technology transfer possibilities and implementation procedures.
Solar pasteurization, solar distillation, and riverbank filtration are low cost technologies with differing scales of implementation that are most suited to developing regions of the world. While solar pasteurization and solar distillation are ideal for household units, riverbank filtration is applicable to the scale of towns or cities. The chapter on membrane desalination emphasizes the processes involved, addresses their environmental impacts and mitigation strategies, and finally discusses the potential of membrane desalination applications to small- and medium-scale treatment systems.
