"... 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.

Tackling the issue of water and wastewater treatment nowadays requires novel approaches to ensure that sustainable development can be achieved. Water and wastewater treatment should not be seen only as an end-of-pipe solution but instead the approach should be more holistic and lead to a more sustainable process. This requires the integration of various methods/processes to obtain the most optimized design. Integrated and Hybrid Process Technology for Water and Wastewater Treatment discusses the state-of-the-art development in integrated and hybrid treatment processes and their applications to the treatment of a vast variety of water and wastewater sources. The approaches taken in this book are categorized as (i) resources recovery and consumption, (ii) optimal performance, (iii) physical and environmental footprints, (iv) zero liquid discharge concept and are (v) regulation-driven. Through these categories, readers will see how such an approach could benefit the water and wastewater industry. Each chapter discusses challenges and prospects of an integrated treatment process in achieving sustainable development. This book serves as a platform to provide ideas and to bridge the gap between laboratory-scale research and practical industry application. - Includes comprehensive coverage on integrated and hybrid technology for water and wastewater treatment - Takes a new approach in looking at how water and wastewater treatment contributes to sustainable development - Provides future direction of research in sustainable water and wastewater treatment
This brand new manual provides thorough coverage of water membrane science, concepts, and theory. Chapters discuss membrane applications, testing of membrane systems, design concepts and operations, costs, residuals, plus the various manufactures. The final chapter covers future trends in low-pressure membranes followed by extensive tables and figures.
This volume brings together diverse voices relating to the critical issue of water management in one of the world’s most politically volatile areas: the Middle East. The book collects the opinions of Palestinians, Israelis, Jordanians as well as international experts on creating a holistic and comprehensive view of water management challenges and strategies in the Middle East.
While the treatment of water and exhaust gas using ultraviolet (UV) light offers both ecological and economic advantages, information on photo-initiated advanced oxidation technologies (AOTs) has been dispersed among various journals and proceedings until now. This authoritative and comprehensive handbook is the first to cover both the photochemical fundamentals and practical applications, including a description of advanced oxidation processes (AOPs) and process engineering of suitable photoreactors. The author presents various real-world examples, including economic aspects, while many references to current scientific literature facilitate access to current research topics relevant for water and air industries. Throughout, over 140 detailed figures visualize photochemical and photophysical phenomena, and help in interpreting important research results. From the foreword by James R. Bolton (President of Bolton Photosciences Inc., Executive Director of the International Ultraviolet Association (IUVA)): "Prof. Oppenländer is well qualified to write about the AOPs/AOTs, since he has contributed to this literature in a very significant manner. This book will be of considerable value to graduate students, science and engineering faculty, scientists, process engineers and sales engineers in industry, government regulators and health professionals."
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.
