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

In the wake of the Millennium Declaration and the Johannesburg resolutions, many countries have begun to address or re-write their policies regarding water supply and wastewater disposal. The goal is to provide high-quality drinking-water for more people and to safely dispose of spent waters from a large portion of the population than today. This book, as its predecessors, 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. 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 and properties, and the reuse of chemicals and chemically-treated waters and sludges. Chemical Water and Wastewater Treatment VIII is a valuable resource for managers, scientists, plant operators and others interested in chemical water and wastewater treatment technology.

Chemical Water and Wastewater Treatment V by Hermann H. Hahn,Erhard Hoffmann,Hallvard Odegaard Pdf

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.

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 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.

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.

Treatment of Wastewater from the Production of Polyhydric Organics by M. A. Zeitoun,Dow Chemical Company. Texas Division,W. F. McIlhenny Pdf

A number of extremely useful and widely produced compounds are produced by the alkaline hydrolysis of chlorohydrins such as ethylene and propylene glycols and glycerin. The brine wastewater resulting from the production of the glycols is characterized by a high salt content (8-10% NaCl), excess alkalinity, and the presence of several organic compounds. Several processes were examined in the laboratory to determine the usefulness for the treatment of the brine wastewater. The processes tried included solvent extraction of the glycol wastewater with secondary or tertiary amines; adsorption of glycols on activated carbon; biological oxidation of propylene glycol wastewater; and an activated sludge process. Only the last was successful. The operational and design parameters determined from a pilot plant operation were used to design an activated sludge plant to treat 6 MGD of wastewater resulting from the production of 1.2 million pounds per day of propylene glycol. Costs are given.
