The past few years have seen the emergence of a growing, widespread desire in this country, and indeed everywhere, that positive actions be taken to restore the quality of our environment, and to protect it from the degrading effects of all forms of pollution-air, noise, solid waste, and water. Since pollution is a direct or" indirect consequence of waste, if there is no waste, there can be no pollution, and the seemingly idealistic demand for" zero discharge" can be construed as a demand for zero waste. However, as long as there is waste, we can only attempt to abate the consequent pollution by converting it to a less noxious form. In those instances in which a particular type of pollution has been recognized, three major questions usually arise: 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? The principal intention of this series of books is to help the reader to formulate answers to the last two of the above three questions. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major factor contributing to the success of environmental engineering, and in large measure has accounted for the establishing of a "methodology of pollution control.
Leading pollution control educators and practicing professionals describe how various combinations of different cutting-edge process systems can be arranged to solve air, noise, and thermal pollution problems. Each chapter discusses in detail a variety of process combinations, along with technical and economic evaluations, and presents explanations of the principles behind the designs, as well as numerous variant designs useful to practicing engineers. The emphasis throughout is on developing the necessary engineering solutions from fundamental principles of chemistry, physics, and mathematics. The authors also include extensive references, cost data, design methods, guidance on the installation and operation of various air pollution control process equipment and systems, and Best Available Technologies (BAT) for air thermal and noise pollution control.

Complex environmental problems are often reduced to an inappropriate level of simplicity. While this book does not seek to present a comprehensive scientific and technical coverage of all aspects of the subject matter, it makes the issues, ideas, and language of environmental engineering accessible and understandable to the nontechnical reader. Improvements introduced in the fourth edition include a complete rewrite of the chapters dealing with risk assessment and ethics, the introduction of new theories of radiation damage, inclusion of environmental disasters like Chernobyl and Bhopal, and general updating of all the content, specifically that on radioactive waste. Since this book was first published in 1972, several generations of students have become environmentally aware and conscious of their responsibilities to the planet earth. Many of these environmental pioneers are now teaching in colleges and universities, and have in their classes students with the same sense of dedication and resolve that they themselves brought to the discipline. In those days, it was sometimes difficult to explain what indeed environmental science or engineering was, and why the development of these fields was so important to the future of the earth and to human civilization. Today there is no question that the human species has the capability of destroying its collective home, and that we have indeed taken major steps toward doing exactly that. And yet, while, a lot has changed in a generation, much has not. We still have air pollution; we still contaminate our water supplies; we still dispose of hazardous materials improperly; we still destroy natural habitats as if no other species mattered. And worst of all, we still continue to populate the earth at an alarming rate. There is still a need for this book, and for the college and university courses that use it as a text, and perhaps this need is more acute now than it was several decades ago. Although the battle to preserve the environment is still raging, some of the rules have changed. We now must take into account risk to humans, and be able to manipulate concepts of risk management. With increasing population, and fewer alternatives to waste disposal, this problem is intensified. Environmental laws have changed, and will no doubt continue to evolve. Attitudes toward the environment are often couched in what has become known as the environmental ethic. Finally, the environmental movement has become powerful politically, and environmentalism can be made to serve a political agenda. In revising this book, we have attempted to incorporate the evolving nature of environmental sciences and engineering by adding chapters as necessary and eliminating material that is less germane to today's students. We have nevertheless maintained the essential feature of this book -- to package the more important aspects of environmental engineering science and technology in an organized manner and present this mainly technical material to a nonengineering audience. This book has been used as a text in courses which require no prerequisites, although a high school knowledge of chemistry is important. A knowledge of college level algebra is also useful, but calculus is not required for the understanding of the technical and scientific concepts. We do not intend for this book to be scientifically and technically complete. In fact, many complex environmental problems have been simplified to the threshold of pain for many engineers and scientists. Our objective, however, is not to impress nontechnical students with the rigors and complexities of pollution control technology but rather to make some of the language and ideas of environmental engineering and science more understandable.
Almost Every Advance In Science And Technology Brings New And Unexpected Problems In Its Wake. Thus The Motorcar, Aeroplane, High-Speed Machine Tools, Compressors And The Gas Turbine All Beneficial In Themselves Have Contributed, Along With Countless Other Developments, To The Background Of Noise Which Is Fast Becoming One Of The Distinguishing Features Of Life Today. With Rapid Increase In Urbanisation And Industrialisation, Noise Has Been On The Increase And It Has Invaded Man S Most Private And Precious Possession, His Mental Sanctuary. Noise Has Assumed Alarming Proportions And Has Become Even More Dangerous Than Water And Air Pollution. Noise Pollution Is A Slow And Insidious Killer. It Is A Serious Health Hazard But Still The Noise Level Is Rising Higher And Higher In The Cities. Thus, Noise Is No Less Pollutant Than The Toxic Chemicals In Our Environment.It Is The Regrettable Fact That Nearly Every Machine, Device Or Gadget Devised For The Convenience Of Man Produces Some Degree Of Sound, Which, Being More Often Than Not Unwanted, Must Be Classed As Noise. Fortunately, Noise Can Be Controlled And Methods For Reducing Noise Levels Are Well Known To Acoustical Engineers. Financial Problems And Special Difficulties Inevitably Arise In Practice, But, Given The Principles Involved Are Clearly Understood, Noise Reduction Need Not Involve Excessive Expenditure. Excessive And Wasteful Expenditure Is Likely To Be Incurred In Cases When Hit-Or-Miss Methods Are Employed And Show Little Or No Success In The Final Result.The Successful Treatment Of Any Noise Problem Depends To A Large Extent On The Way In Which The Problem Is Approached And On The Care With Which The Plans Are Prepared. Controlling Noise Is An Increasing Challenge To The Industrial World.This Textbook On Noise Pollution And Its Control Has Been Written To Provide Basic Concepts Of Noise, Its Effects And Control In Industrial And Non-Industrial Sources. Various Engineering Approaches Such As Use Of Silencers, Mufflers, Shields, Barriers And Improvement In The Design Of Machinery And Reduction Of Noise At Source Have Been Discussed In Detail. The Textbook Also Includes The Various Control Measures Of Noise In Industries Such As Paper, Mining, Food Processing, Metal, Rubber And Plastics Etc. The Instruments For Analysis Of Noise Are Also Discussed In Depth. The Present Book Emphasizes That General Measures Can Also Be Adopted To Control And Prevent The Occurrence Of Noise Pollution. These Measures Include General Awareness Among The People By Educating Through Newspapers, Tv And Co-Ordination With Planners And Environmental Authorities.It Is Hoped That The Book Will Prove Highly Useful To All General Readers Concerned With Environmental Degradation. More Importantly, It Ideally Serves The Academic Purpose Of Students And Researchers Of Environment Science.
