Since the First Edition appeared, Air Pollution Control: A Design Approach has become the leading air pollution control text on the strengths of good writing, comprehensive coverage, an emphasis on design, and excellent real-world examples. The Third Edition continues this tradition of excellence, incorporating new and updated information throughout the text while retaining the topical organization and features that have made it an invaluable learning tool for instructors and students alike. The Third Edition successfully achieves two main objectives. First, it presents detailed information about air pollution and its control. Causes, sources, effects, and regulation of air pollution are discussed, as well as the economic analysis necessary for efficient and effective control of air pollution. Second, and perhaps more importantly, it provides formal design training for engineering students. Written for engineers from a variety of disciplines, this text offers numerous diagrams, examples, and end-of-chapter problems emphasizing key concepts and design techniques. Outstanding features include: 1) two new chapters: Biofiltration and Indoor Air Quality; 2) current cost estimation data and techniques; 3) updated air quality trends; 4) 31 sample P. E. Examination problems with worked-out solutions; and 5) new end-of-chapter problems in every chapter.
