It was intended to return with the International Gothenburg Symposia every other time to the birthplace of these events, Gothenburg in Sweden. But instead the 8th symposium has been invited to be organized and held in Prague, i. e. in the midst of Central and Eastern Europe a region now keen on intensified environmental control. This attests that the symposia have attained such standing in the interna tional world of operators, designers, officers and researchers in water treatment technology that their presence in various parts of the world has been requested. And this ever growing significance, in short the success of this conference series, stems form the fact that the symposia offer a unique platform for the exchange of ideas and experiences on all aspects of water and wastewater treatment between administrators, engineers and scientists. The content of this book, i. e. the schedule of the symposium lectures, results for the most part from a vast response to an international call for papers. Many excellent contributions are included in this volume but at the same time many outstanding ones could not be included for lack of time and space. The total sum of these contributions document again the development in the field, both in terms of new technological (and other) developments as well as public and administrative acceptance and approval of solutions offered.

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.

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

For the ninth Gothenburg Symposium time design and operation engineers as well as supervising and funding administrators in chemical water and waste water treatment, have come together to exchange ideas, experiences and personal views on issues of water and waste water management. While the main thrust of past symposia was in the description of the technological know-how of existing chemical unit-operations in water technology this ninth symposium focuses in addition on aspects of overall energy and mass flux analyses, the strive for more and more sustainable solutions (not only in technological turns) and public private partnership in all areas of water management. As the symposium in its effort to address also different geographical areas and therefore different water problems moved to Istanbul in Turkey a special effort was made in developing a platform for industrial water management.

The question of whether or not we will reach the ambitious goal of the Millennium Declaration still dominates the discussions of water supply and sanitation experts on all levels, governmental, institutional, technological and operational. Our contribution, the Proceedings of the 12th Gothenburg Symposium, the symposium for the sharing of scientific and practical experience in integrated water resources management, is mainly a technological one. This book, as has its predecessors in the series, provides information and technical solutions to accomplish this mammoth task. It is the outcome of collective experience and know-how exchanged between experts in the field of water technology from all over the world, from the Americas, from Central and Southern Africa, from Europe and from different parts of Asia. However, we must realise that very often it is not the technological development that determines progress but rather the legal, financial and organisational framework. And so this book and this symposium differs from its predecessors in that, for the first time, the focus is also on these non-technical aspects that may or may not set the stage for our technological solutions. 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 as sludge production, as well as properties, and the reuse of chemicals and chemically-treated waters and sludges. Chemical Water and Wastewater Treatmentis a valuable resource for managers, scientists, plant operators and others interested in chemical water and wastewater treatment technology.

The biennial International Gothenburg Symposia on Chemical Water and Waste water Treatment have proven to be a unique platform for the exchange of ideas and experiences between administrators, engineers and scientists active in the fields of water supply, wastewater disposal and pollution control. The First Symposium (Gothenburg, 1984) provided a long needed survey over theory and application of chemical water and wastewater treatment. The Second Symposium (Berlin, 1986) was devoted to aspects of recycling in chemical water and wastewater technology. The Third Symposium (Gothenburg, 1988) recognised the growing need and the potentials of pretreatment. These proceedings of the 4th Symposium focus on technology transfer from chemical treatment theory to practical treatment of drinking water and industrial or domestic wastewater. The contributions are devoted to questions of floc for mation and floc separation as well as problems and practical solutions associated with chemicals and dosing control. Special attention is given to the combination of chemical and biological processes for nutrient removal from wastewater. It is the editors' privilege to acknowledge the invaluable help from the authors of this book. It is the editors' hope that they might convey the significance and potential of chemical treatment in solving the challenging problems water purification, wastewater disposal and pollution control.

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.
