Outlining the science and technology of the processes used in treating water to meet specific water quality standards, this book emphasizes the common process fundamentals, whether used in drinking water production or wastewater treatment systems. Operations discussed include destabilization of suspensions, sedimentation flotation and sand filtration processes, chemical precipitation, membrane filtration, biological and anaerobic processes, disinfection and fluoridation of water supplies. Includes design examples and computer programs that are available on the Internet.

This book is divided into three sections: the first reviews the main processes available for treating water for drinking (potable) purposes, the second goes into some detail about the design and operation of the non-filtration (clarification) processes, and the third deals exclusively with filtration and related applications. It is intended as a source of practical information rather than a theoretical research treatise and includes discussion of component parts of the process units with reasons for design features as well as operating principles.This book fills a gap between general reviews and research papers, and contains much information which is based on experience passed down within organisations and which tends not to be published.

Process Science and Engineering for Water and Wastewater Treatment is the first in a new series of distance learning course books from IWA Publishing. The new series intends to help readers become familiar with design, operation and management of water and wastewater treatment processes without having to refer to any other texts. Process engineering is considered fundamental to successful water and wastewater treatment and Process Science and Engineering for Water and Wastewater Treatment provides the fundamental chemistry, biology and engineering knowledge needed to learn and understand the underlying scientific principles directly relevant to water and wastewater treatment processes. Units in the text covering chemistry and biology include: fundamentals of water chemistry; chemical kinetics and equilibria; colloid and surface chemistry; fundamentals of microbiology; fundamentals biochemistry and microbial kinetics. The concept of Process Engineering is introduced through units on: mass and heat balances; mass and heat transfer; reactor design theory; engineering hydraulics and particle settlement. The text is designed for individual study at the learner?s own pace. Each section contains multiple features to aid learning, including: boxes highlighting key learning points exercises and problems with fully worked solutions to help the reader test their understanding as they progress through the text a comprehensive set of self-assessment questions (with answers) at the end of each unit Designed as a starting point for the other books in the Water and Wastewater Process Technologies Series, this book also provides a self-contained course of learning in the science and engineering for water and wastewater treatment processes. It forms part of the Masters degree programme taught in the School of Water Sciences at Cranfield University, UK.

Principles of Water and Wastewater Treatment Processes is the third book in the Water and Wastewater Process Technologies Series. The book outlines the principle unit operations that are involved in the separation, degradation and utilisation of organic and inorganic matter during water and wastewater treatment. The module builds on the subjects of chemistry, biology and engineering covered in Process Science and Engineering for Water and Wastewater Treatment (Module 1) and provides a descriptive introduction to unit operations that are further described with design and operational details in later books in the series. The text of Principles of Water and Wastewater Treatment Processes has been divided into the following Units: Water Quality Process Flowsheeting Physical Processes Chemical Processes Sorption Processes Biological Processes Membrane Processes Sludge Treatment Utilisation Odour Management These units have has been designed for individual self-paced study that includes photographs, illustrations and tables and describe the form, function and application of unit operations for the treatment of water and wastewater. Each section of the text gives step-by-step learning in a particular subject, that includes an approximation of how long you will need to spend on that section and provides key points that highlight the principles of the different sections. Each unit includes exercises to help understand the material in the text, self-assessment questions to test your understanding and text references.

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

Lauded for its engaging, highly readable style, the best-selling first edition became the premier guide for nonengineers involved in water and wastewater treatment operations. Water and Wastewater Treatment: A Guide for the Nonengineering Professional, Second Edition continues to provide a simple, nonmathematical account of the unit processes used to treat both drinking water and wastewater. Completely revised and expanded, this second edition adds new material on technological advances, regulatory requirements, and other current issues facing the water and wastewater industries. Using step-by-step, jargon-free language, the authors present all the basic unit processes involved in drinking water and wastewater treatment. They describe each unit process, the function of the process in water or wastewater treatment, and the basic equipment used in each process. They also explain how the processes fit together within a drinking water or wastewater treatment system and discuss the fundamental concepts that constitute water and wastewater treatment processes as a whole. Avoiding mathematics, chemistry, and biology, the book includes numerous illustrations for easy comprehension of concepts and processes. It also contains chapter summaries and an extensive glossary of terms and abbreviations for quick reference.
