Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Aquatic chemistry students need a solid foundation in fundamental concepts as well as numerical techniques for solving the variety of problems they will encounter as practicing engineers. For over a decade, Mark Benjamin’s Water Chemistry has brought to the classroom a balanced coverage of fundamentals and analytical algorithms in a student-friendly, accessible way. The text distinguishes itself with longer and more detailed explanations of the relevant chemistry and mathematics, allowing students to understand not only which techniques work best for a given application, but also why those techniques should be applied and what their limitations are. The end result is a solid, thorough framework for comprehending equilibrium in complex aquatic systems. The second edition includes a thorough introductory explanation of chemical reactivity and a new chapter on reaction kinetics, providing much-needed context, as well as full treatments of the tableau method and TOTH equation. The discussion of the thermodynamic perspective on chemical reactivity has been extensively revised. The entire book now integrates Visual Minteq—the most popular software for analyzing chemical equilibria—into the problem-solving approach. Additional exercises range more widely in difficulty, giving instructors more flexibility and diversity in their assignments.

Modeling results for pure liquid water, water near ions, water at interfaces, water in biological microsystems, and water under other types of perturbations such as laser fields are described. Connections are made throughout the book with statistical mechanical theoretical methods on the one hand and with experimental data on the other. The book is expected to be useful not only for theorists and computer analysts interested in the physical, chemical, biological and geophysical aspects of water, but also for experimentalists in these fields.

Book excerpt: "Water is the most every day of substances. It pours from our taps and falls from the sky. We drink it, wash with it, and couldn't live without it. Yet, on closer examination it is also a very strange substance (it is one of only a very small number of molecules which expand when cooled). Look closer again and water reveals itself as a key to a scientific story on the biggest of canvases. Water is crucial to our survival - life depends on it - but it was also fundamental in the origins of life on Earth. The millions of gallons of water which make up our rivers, lakes and oceans, originated in outer space. How it arrived here and how those molecules of water were formed, is a story which takes us back to the beginning of the universe. Indeed, we know more about the depths of space than we do about the furthest reaches of the oceans. Water has also shaped the world we live in. Whether it is by gently carving the Grand Canyon over millennia, or in shaping how civilisations were built; we have settled our cities along rivers and coasts. Scientific studies show how we feel calmer and more relaxed when next to water. We holiday by the seas and lakes. Yet one day soon wars may be fought over access to water. The Water Book will change the way you look at water. After reading it you will be able to hold a glass of water up to the light and see within it a strange molecule that connects you to the origins of life, the birth (and death) of the universe, and to everyone who ever lived."--From publisher.

Available in PDF, EPUB and Kindle. Book excerpt: Biphasic Chemistry and The Solvent Case examines recent improvements in reaction conditions, in order to affirm the role of chemistry in the sustainable field. This book shows that those who work within the chemistry industry support limits for the use of toxic or flammable solvents, since it reduces the purifications to simple filtrations. Thanks to commercial scavengers, solid phase syntheses are now available to all. Fluorine biphasic catalysis enables extremely efficient catalyst recycling and has a high applicability potential at the industrial level. This book also reviews the many studies that have shown that water is a solvent of choice for most synthetic reactions. Particular traits can be obtained and the effects on thermodynamics make it possible to operate at lower temperatures, thereby achieving energy savings. Finally the great diversity of application of the reactions without solvents is illustrated.

Book excerpt: About the Book: Man has always known that air (oxygen) and water are the two most important items for life. Yet, few people are aware of the scientific facts regarding water. In a sense, water is a weird compound of nature. Man being highly selfish exploiting the natural resource like water and also making water bodies getting polluted. The present work is an attempt to bring awareness among public about the usage of water in limited quantities and save the water for future generations besides recharging the depleting water resources. This book provides the knowledge of multidimensional aspect of aquatic environment which involves the sources, compositions, chemical reactions and transport of water. The chemistry of water exposed to the atmosphere has been quite different from that of water at the bottom of rivers and lakes. One must know the factors which influence this 'Water Chemistry' and its movement with the 'Eco System'. About the Author: Alla Appa Rao is at present working as senior lecturer in Chemistry in the Department of Technical Education, Govt. of Andhra Pradesh. He is postgraduate in Chemistry, Sociology and Education from Andhra University. He is an author of so many books in Mother Tongue among one is published by Pottisriramalu Telugu University, Hyderabad i.e., Environmental Studies (in Telugu).

This book was released on 2012-08-31 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is considerable concern about the formation of potentially harmful degradation products as well as oxidation products from the reaction with the matrix components. In recent years, a wealth of information on the products that are formed has accumulated, and substantial progress in understanding mechanistic details of ozone reactions in aqueous solution has been made. Based on the latter, this may allow us to predict the products of as yet not studied systems and assist in evaluating toxic potentials in case certain classes are known to show such effects. Keeping this in mind, Chemistry of Ozone in Water and Wastewater Treatment: From Basic Principles to Applications discusses mechanistic details of ozone reactions as much as they are known to date and applies them to the large body of studies on micropollutant degradation (such as pharmaceuticals and endocrine disruptors) that is already available. Extensively quoting the literature and updating the available compilation of ozone rate constants gives the reader a text at hand on which his research can be based. Moreover, those that are responsible for planning or operation of ozonation steps in drinking water and wastewater treatment plants will find salient information in a compact form that otherwise is quite disperse. A critical compilation of rate constants for the various classes of compounds is given in each chapter, including all the recent publications. This is a very useful source of information for researchers and practitioners who need kinetic information on emerging contaminants. Furthermore, each chapter contains a large selection of examples of reaction mechanisms for the transformation of micropollutants such as pharmaceuticals, pesticides, fuel additives, solvents, taste and odor compounds, cyanotoxins.
