"... Because of the dual benefit of effectively treating against Cryptosporidium and Giardia, many utilities are viewing UV disinfection as a potential means for meeting upcoming regulatory requirements of increased levels of disinfection with no appreciable increase in disinfection byproducts. As part of a multi-barrier treatment process, UV disinfection has the potential of meeting these restrictive requirements." -- Introduction, p. 1.

Several general books are available on ultraviolet light and its applications. However, this is the first comprehensive monograph that deals with its application to water and wastewater treatment. There is a rapidly growing interest in using UV light in water sanitation due to the increased knowledge of the potential health and environmental impacts of disinfection byproducts. Ultraviolet Light in Water and Wastewater Sanitation integrates the fundamental physics applicable to water and wastewater sanitation, the engineering aspects, and the practical experience in the field. The text analyzes the concerns associated with this application of UV light and brings together comprehensive information on the presently available UV technologies applicable to water and wastewater treatment including: lamp technologies, criteria of evaluation and choice of technology; fundamental principles; performance criteria for disinfection; design criteria and methods; synergistic use of UV and oxidants (advanced oxidation); and functional requirements and potential advantages and drawbacks of the technique. Ultraviolet Light in Water and Wastewater Sanitation is the only treatise currently available combining fundamental knowledge, recommendations for design, evaluations of performance, and future prospects for this application. Water and wastewater treatment professionals, water utility employees, governmental regulators, and chemists will find this book an essential and unique reference for a technology which has received growing regulatory acceptance.

With the rapid development of Chinese urbanization in the 21st century, "urban diseases" become more serious, mainly manifested in water environmental pollution, urban flooding, water shortage, and deterioration of water ecology. It is necessary to establish a modern rainwater management system, scientifically solve the problem of excess urban rainwater and to improve water environment quality. Improvement of water environment quality is conducive to the ecological function of a sponge city. Sponge city construction has contributed to control non-point source pollution. Sponge systems cause the stagnation and purification of rainwater runoff, which is an important guarantee for water environment quality. This monograph summarizes theories and practices of the integrated water environment treatment in Chongqing, a typical representative mountainous city in the Three Gorges Reservoir Region. Based on the mountainous terrain and unique water environment characteristics in the Three Gorges Reservoir Region, the monograph analyzes measures and difficulties in the basin water environment integrated treatment. Moreover, the monograph makes suggestions for risk management amid drainage systems during the COVID-19 epidemic.

Water is the next oil over which nations will fight wars. Severe water shortages already affect some 450 million people living in 29 countries, and analysts have predicted that tensions over water rights in Asia, Africa, and the Middle East could explode into violent clahses and even full-blown wars if governments do not manage existing water supplies more efficiently. Worldwide, 220 river basins are shared by two or more countries and the tensions caused by water scarcity will escalate in this century---the water shortage problems will be exacerbated by global warming and its associated unpredicatable weather patterns. In 2001, the CIA predicted that by 2015, almost half of the world?s population, more than 3 billion people, will live in "water-stressed"countries. How can communities that don't have millions of dollars to hire multinational engineering companies to build highly advanced (but also highly energy and chemical intensive) water- and wastewater-treatment systems? This book is full of practical, low-cost, effective, ecological and economically sustainable, environmental friendly solutions for communities. In the 762 pages (with 185 diagrams and 910 photographs), readers will be introduced to many types of ecologically designed and engineered water- and wastewater-treatment systems, which communities can build with locally available labor, expertise, and resources.

The research project CuveWaters developed and implemented adapted technologies and accompanying measures to support the national process towards an Integrated Water Resources Management (IWRM). The aim is to give people in the Cuvelai-Etosha Basin reliable access to clean water over the long term, thus enhancing their livelihood and health, and to create job opportunities. IWRM relies on solutions that use various sources, types and qualities of water for different purposes. CuveWaters implemented pilot plants for rain- and floodwater harvesting, groundwater desalination, as well as facilities for sanitation and water reuse. Technical components of the project were framed by societal and scientific components. Integrated Water Resources Management in Water-scarce Regions provides a comprehensive view on the complexity and interconnectedness of findings and conclusions regarding the principle strategic approach within the CuveWaters project’s concept. The book aims to present the work of technical, social and natural scientists but also of media professionals: It gives thematically focussed details on the three technology-based solutions which go beyond mere technical considerations and embed this into the overarching process towards IWRM in Namibia. Finally, it critically addresses lessons learnt and limits of projects in the context of research for implementation. This book is of great value to experts, professionals and also students and academics in the areas of water management, technology development and implementation and transdisciplinary science.
