Book Description
Treating potable and polluted water for the world's population is still one of our most important challenges. The United Nations estimate that more than 1.2 billion people suffer from inadequate water supply and an even larger number, up to 4 billion people, are without hygienic disposal of waste and wastewater. Water technology and the necessary "know-how transfer", has been the key objective of the Gothenburg symposia from the very beginning. The contents of this book respond to these challenges and demonstrate the impressive development of the field of chemical waster and wastewater treatment. The Chemical Water and Wastewater Treatment Series provides authoritative coverage of the key current developments in the chemical treatment of water and wastewater in theory or practice and related problems such a s sludge production and properties, and the reuse of chemicals and chemically-treated waters and sludges. For the tenth in the series, the contributions document the development if the field of chemical water and wastewater technology, both in terms of new technological developments as well as public and administrative acceptance and approval of the solutions offered. Such new developments include the use of membrane technology, the application of computational tools for kinetic process modelling and optimisation as well as the use of advanced oxidation processes in actual water treatment. Chemical Water and Wastewater Treatment VII covers fundamental science, new technological developments and practical experience and is an invaluable reference source for engineers scientists and administrators, active in the treatment of drinking water, municipal and industrial wastewater and sludges.

Book Description
Based upon half a century of research by the authors, Physical and Chemical Separation in Water and Wastewater Treatment addresses the whole water cycle spectrum, from global hydrological cycle, urban-regional metabolic cycle to individual living and production cycle, with respect to quality control technology based on fundamental science and theories. For every treatment process, basic scientific and environmental physical and chemical natures are explained with respect to those of water and its impurities. Health danger and risks for human beings are also covered. The authors define water qualities on a “Water Quality Matrix” composed of 35 elements. The vertical axis (row), has individual 7digit impurity size from 10-10m (water molecule 3?) to 10-3m (0.1mm sand grains) and in the horizontal axis(column) there are 5 categories of surrogate chemical and biochemical quality indices. The same 35 element matrix is used to correspond with several typical water quality treatments, unit-operation/unit-process, with a suitable characteristic grouping of the elements. The authors then present “the Water Quality Conversion Matrix” or “Water Quality Treatment Matrix”. With respect to typical treatment processes, the basic concept and scientific background are explained and the background of the technologies is clarified. Mechanisms of the process are explained and a kinetic process is formulated. The kinetics are experimentally verified quantitatively with important equilibrium and rate constants. Based on the authors’ research, various new treatment technologies are proposed with high efficiency, high capacity and less energy, and with steady operation ability. This comprehensive reference book is intended for undergraduate and graduate students, and also serves as a guide book for practical engineers and industry and university researchers.

Book Description
The books currently available on this subject contain some elements of physical-chemical treatment of water and wastewater but fall short of giving comprehensive and authoritative coverage. They contain some equations that are not substantiated, offering empirical data based on assumptions that are therefore difficult to comprehend. This text brings together the information previously scattered in several books and adds the knowledge from the author's lectures on wastewater engineering. Physical-Chemical Treatment of Water and Wastewater is not only descriptive but is also analytical in nature. The work covers the physical unit operations and unit processes utilized in the treatment of water and wastewater. Its organization is designed to match the major processes and its approach is mathematical. The authors stress the description and derivation of processes and process parameters in mathematical terms, which can then be generalized into diverse empirical situations. Each chapter includes design equations, definitions of symbols, a glossary of terms, and worked examples. One author is an environmental engineer and a professor for over 12 years and the other has been in the practice of environmental engineering for more than 20 years. They offer a sound analytical mathematical foundation and description of processes. Physical-Chemical Treatment of Water and Wastewater fills a niche as the only dedicated textbook in the area of physical and chemical methods, providing an analytical approach applicable to a range of empirical situations Contents Introduction Characteristics of Water and Wastewater Quantity of Water and Wastewater Constituents of Water and Wastewater Unit Operations of Water and Wastewater Treatment Flow Measurements and Flow and Quality Equalizations Pumping Screening, Settling, and Flotation Mixing and Flocculation Conventional Filtration Advanced Filtration and Carbon Adsorption Aeration, Absorption, and Stripping Unit Processes of Water and Wastewater Treatment Water Softening Water Stabilization Coagulation Removal of Iron and Manganese by Chemical Precipitation Removal of Phosphorus by Chemical Precipitation Removal of Nitrogen by Nitrification-Denitrification Ion Exchange Disinfection

Book Description
Water pollution occurs when toxic pollutants of varying kinds (organic, inorganic, radioactive and so on) are directly or indirectly discharged into water bodies without adequate treatment to remove such potential pollutants. Today's sources of these potential pollutants, which cause high deterioration of freshwater quality, are city sewage and industrial waste discharge, human agricultural practices, industrial waste disposal practices, mining activities, civil and structural work activities and obviously natural contamination with climate change. When our water is polluted, it is not only devastating to the environment but also to human health. Therefore, development of water and wastewater treatment processes to alleviate water pollution has been a challenging and demanding task for engineers, scientists and researchers. Perhaps this is even more challenging for underdeveloped and developing countries, where water and wastewater treatment facilities, knowledge and infrastructure are limited. Water and wastewater treatment processes are broad and often multidisciplinary in nature, comprising a mixture of research areas including physical, chemical and biological methods to remove or transform various potential pollutants. This is in hopes to achieve acceptable water quality and satisfy governmental and environmental protection agencies' laws and regulations. With these objectives, this book has been written in order to provide various research results and compilation and up-to-date development on the current states of knowledge and techniques in the broad field of water and wastewater treatment processes. Basically, this book will give a comprehensive understanding and advancement and application of various physical, chemical and biological treatment methods in the reduction of potential pollutants (inorganics/organics) from water and wastewater. There are a total 18 book chapters contributed by large number of expert authors around the world, covering the following main research areas: Physical, chemical and biological water treatment processes such as adsorption, biosorption, coagulation/flocculation, electrocoagulation, denitration, membrane filtration/separation, photo-catalytic reduction, advanced oxidation, nutrients removal by struvite crystallisation and nanotechnology; Physical, chemical and biological methods for municipal wastewater and industrial wastewater treatment plants such as primary-secondary sludge treatments, anaerobic digestions, aerobic treatment, activated sludge processes, dewaterability by flocculants, pre-treatments of sludge and rheology of sludge in wastewater treatment; Various operational units/equipment and process control of wastewater treatment plant.

Book Description
This second edition demonstrates how chemistry influences the design of water treatment plants and how it should influence the design. Historically, water treatment plants have been designed from hydraulic considerations with little regard to chemical aspects. The many chemical reactions used for removal of pollutants from water simply cannot be forced to occur within current designs. This book re-examines this traditional approach in light of today's water quality and treatment. Will current water treatment processes be sufficient to meet future demands or will new processes have to be devised? Chemistry of Water Treatment assesses the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking water Act, providing expert information to persons responsible for the production of potable water into the next century.
