"... 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.

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.
Completely up-to-date coverage of water treatment facility design and operation This Second Edition of Susumu Kawamura's landmark volume offerscomprehensive coverage of water treatment facility design, from thebasic principles to the latest innovations. It covers a broadspectrum of water treatment process designs in detail and offersclear guidelines on how to choose the unit, process, and equipmentthat will maximize overall efficiency and minimize maintenancecosts. This book also explores many important operational issuesthat affect today's plant operators and facility designers. This new edition introduces several new subjects, including valueengineering, watershed management, dissolved air flotation process,filtered reservoir (clearwell) design, and electrical systemdesign. It provides expanded and updated coverage of objectives forfinished water quality, instrumentation and control, disinfectionprocess, ozonation, disinfection by-product control, the GACprocess, and the membrane filtration process. Other importantfeatures of this Second Edition include: * Practical guidance on the design of every water treatment plantcomponent * New information on plant layout, cost estimation, sedimentationissues, and more * English and SI units throughout * Help in designing for compliance with water treatment-relatedgovernment regulations Supplemented with hundreds of illustrations, charts, and tables,Integrated Design and Operation of Water Treatment Facilities,Second Edition is an indispensable, hands-on resource for civilengineers and managers, whether working on new facilities orredesigning and rebuilding existing facilities.
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.
Novel Approaches towards Wastewater Treatment and Resource Recovery Technologies discusses various cost-efficient aspects of wastewater treatment along with resource recovery options. The book covers biological wastewater treatment, the application of membranes and their modifications, advanced oxidation techniques, and the application of nanoparticles for the enhancement of performance as well as various integrated technologies for resource recovery along with pilot scale potentials. The book covers both domestic and industrial wastewaters and provides resources for sustainable solutions. It provides the basic fundamentals and recent updated data. Case studies are included to give the glimpse of the real-world application. Similarly, pilot scale studies are considered for real life implementation of the concept. - Covers sustainable, bio-electrochemical recovery of nutrients and other value-added products from wastewater - Discusses advanced oxidation processes and membranes processes enabling treatment of complex wastewaters for final reuse - Treats domestic/industrial operation and scale-up challenges of wastewater treatment for resource recovery - Includes case studies and pilot scale studies for covering and providing all data and information to the readers in a systematic manner for their easy implementation
