Based on the classic text by Fair, Greyer, and Okun, this new edition has been completely revised and updated including eight completely new chapters by university professors and engineers practicing in the field. It reflects current practice, includes access to an academic version of the commercial software Haestad Methods Water Solutions by Bentley, and now includes homework problems. This is a time of mounting urbanization and industrialization and resulting stress on water and wastewater systems. Clean and ample sources of water for municipal uses are becoming harder to find and more expensive to develop. Effective design and efficient operation of engineering works ask, above all, for a fuller understanding and application of scientific principles. The results of scientific research are being incorporated with remarkable success in new designs using both U.S. and SI systems equations, examples and problems as well as new operating procedures. This classic text, now updated, grounds readers in both the science and art of water and wastewater engineering that global engineers need to service their customers and communities.

A successful modern heavy metal control program for any industry will include not only traditional water pollution control, but also air pollution control, soil conservation, site remediation, groundwater protection, public health management, solid waste disposal, and combined industrial-municipal heavy metal waste management. In fact, it should be a total environmental control program. Comprehensive in scope, Heavy Metals in the Environment provides technical and economical information on the development of a feasible total heavy metal control program that can benefit industry and local municipalities.The book discusses the importance and contamination of metals such as lead, chromium, cadmium, zinc, copper, nickel, iron, and mercury.

Most industrial and hazardous waste management resources cover the major industries and provide conventional in-plant pollution control strategies. Until now however, no book or series of books has provided coverage that includes the latest developments in innovative and alternative environmental technology, design criteria, managerial decision methodologies, and regional and global environmental conservation. The new Handbook of Advanced Industrial and Hazardous Wastes Treatment—together with its predecessor, the Handbook of Industrial and Hazardous Wastes Treatment—forms a complete and up-to-date resource that contains all the necessary technical information on hazardous industrial waste treatment. Providing in-depth coverage of treatment and management technologies in wide-ranging industries that readers simply won’t find anywhere else, this cutting-edge text addresses wastes in areas including metal finishing, food processing, milk production, foundries, and chemical manufacturing. It covers basic and advanced principles and applications in contemporary hazardous and industrial waste treatment and explores new methods of clean production, waste minimization, and the treatment of landfills and underground storage tanks. Coverage includes the latest developments in legislation, regulations, soil remediation, brownfield site restoration, bioremediation, enzymatic processes, and much more. Complete with numerous figures, tables, examples, and case histories, this book provides technical and economical information on how to develop a total environmental control program that can benefit both industry and local municipalities. This book combined with the Handbook of Industrial and Hazardous Wastes Treatment forms a resource that is comprehensive in scope and directly applicable to waste management problems in a broad range of industries.

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise.

The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major contributing factor to the success of en- ronmental engineering, and has accounted in large measure for the establi- ment of a “methodology of pollution control.

An advanced chemical and environmental engineering textbook as well as a comprehensive reference book, this volume is of high value to advanced graduate and undergraduate students, researchers, scientists, and designers of water and wastewater treatment systems. This is an essential part of the Handbook of Environmental Engineering series, an incredible collection of methodologies that study the effects of pollution and waste in their three basic forms: gas, solid, and liquid. Chapters adopt the series format, employing methods of practical design and calculation illustrated by numerical examples, including pertinent cost data whenever possible, and exploring in great detail the fundamental principles of the field.

A critical survey of both the principles and practices involved in water pollution control, potable water treatment, water reuse, and sludge treatment. The authors discuss the performance, potential, and limitations of each major physicochemical treatment process in detail - including the physical and chemical theory behind it, the applications, the design procedures, examples, references, and cost data - as a basis for intelligent planning and realization of treatment systems. Among the processes covered are screening, comminution, flow equalization, neutralization, mixing, coagulation, flocculation, chemical precipitation, oxidation, recarbonization, softening, halogenation, and disinfection. Additional chapters discuss ozonation, electrolysis, sedimentation, dissolved air flotation, gravity filtration, granular activated carbon adsorption, and sludge treatment. The emphasis throughout is on developing the necessary engineering from fundamental principles of chemistry, physics, and mathematics.Two companion volumes, Air Pollution Control Engineering, Volume 1, and Advanced Air and Noise Pollution Control, Volume 2, survey the basic air pollution control technique and the use of multiple techniques to deal with air, thermal, and noise pollution.

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution problems has been a major contributing factor to the success of environmental en- neering, and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.
