Chemical Water and Wastewater Treatment VII by Hermann H. Hahn,Erhard Hoffmann,Hallvard Ødegaard Pdf

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.

Physical and Chemical Separation in Water and Wastewater Treatment by Norihito Tambo,Koichi Ogasawara Pdf

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.

Chemical Water and Wastewater Treatment IV by Hermann H. Hahn,E. Hoffmann,Hallvard Odegaard Pdf

This seventh symposium in the series of biennial Gothenburg Symposia, taking place in Edingburgh 1996 continues to bring together research scientists, designing and operating engineers and funding and supervising administrators. It also has enlarged the scope of its platform by bringing together concerned specialists from Western countries and Central and Eastern Europe and furthermore attempts to bridge the gap between developing and industrialized countries. The traditionally presented topics, such as treatment of potable water and wastwater predominantly by chemical means are of utmost importance for those that need immediate action at reasonable costs. It is particularly noteworthy that an increasing number of contributions address these problems of the emerging need for environmental protection. And more and more presentations are delivered by experts from Central and Eastern Europe and from developing countries. Again the proceedings of this seventh symposium indicate and demonstrate new developments that advance the field of water and wastewater treatment. Be sides the ever present topics there is now a whole section on automation and control, a highly significant topic for water technology that so far has not received too much attention in symposia of this kind addressing theoreticians and prac titioners at the same time.

Physical, Chemical and Biological Treatment Processes for Water and Wastewater by Tushar Kanti Sen Pdf

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.

Chemical Water and Wastewater Treatment IX by Hermann H. Hahn,Erhard Hoffmann,Hallvard Ødegaard Pdf

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.

Basic Water and Wastewater Treatment by T H Y Tebbutt Pdf

Basic Water and Wastewater Treatment discusses the water cycle, flow measurement, physical treatment processes, chemical treatment processes, biological treatment process, and sludge handling and treatment. The book also describes the use of the BASIC computer program to calculate problems involving water pollutants. Flow measurements involve the use of a gauging structure, velocity measurements of a known cross-section, or dilution gauging. To evaluate, in quantitative terms, the effects of a certain pollutant discharged and received by a body of water, the investigator can employ a tool in chemical dilution gauging—the mass balance analysis. Many microorganisms, organic and inorganic compounds degrade in a natural process of self-purification; their decay can be modeled as an exponential function. One standard of water treatment facility or wastewater treatment plant cannot be built to deal with all the various components of water pollution. The book cites relevant standards such as the EC Directive 80/778/EEC: "Quality of Water Intended for Human Consumption" in the EU; the "Safe Drinking Water Act" in the U.S.A.; and the "Guidelines for Drinking Water Quality" issued by the World Health Organization. The book describes water quality parameters, water supply sources, and wastewater collection, including its treatment and disposal.
