This book is dedicated to Marie Durocher and Mary Ruth Gehr, who have shown endless support. The authors are deeply indebted to previous instructors, colleagues, and students who have contributed to this work in numerous ways. Among the many who have made useful suggestions, we wish to express our gratitude for extraordinary efforts to the following people: Dr. J Dudley, Dr. D Frigon, Ms. NM Gaudet, Mr. S Humphries, Mr. Z Lukic, Mr R Marshall, Dr. RM Narbaitz, Dr. S Pavlostathis, Mr. R Reardon, Ms. E Penkarski-Rodon, Dr. Banu rmeci, and Kinjal Mehulkumar Shah.

We had a colleague, a mechanical engineer, who taught a first-year course in mechanics. As his first exercise, he posed the question What is the greatest engineering achievement? to his classes. The students answers ranged from rockets, to computers to automobiles. His answer was the availability of safe drinking water (which distinguishes a developed country from a developing country) in adequate amounts and removal of wastewater. We, of course, agree and hope to make an incremental advancement through this monograph.

The nature of this text has not changed from the first to the second edition, but the technological developments in the 21years since the first edition was published have been astounding. The amount of information available now, in the age of web searching and other electronic resources, is overwhelming. A simple literature search with carefully chosen keywords usually brings up many more than 100 articles.

For those familiar with the first edition, the major upgrades have been in (A host of New Biotreatment Technologies from Membranes to Hybrid Suspended Growth Fixed Film Processes) and a new chapter on life cycle analysis.

This book has been written as a text based on the typical undergraduate background of a civil engineering student. Necessary background information for design and assessment of treatment processes is included in the first sections. These sections do include some review of basic concepts from other courses and should not be considered as replacing the need for these courses. However, these concepts have been focused on the needs of the water quality environmental engineer.

Basic theory of most treatment processes is presented in later sections. The variety of treatment processes is increasing and the issues surrounding their application are often subtle. An introductory coverage of most of the processes is given with more emphasis on common applications. Processes are grouped according to theoretical principles rather than their occurrence in water or wastewater treatment operations. It has been the experience of the authors that many books on the subject simply present formulae without any detailed development: this book addresses that problem. The reader is made aware of theoretical and empirical developments.

This book has a more intense focus on the mechanics of the processes used to treat water or wastewater; design of water distribution and wastewater collection systems are applied hydraulics exercises that are dealt with in other courses. The theory presented in this book is at the level of an undergraduate course. In the past, much of this basic theory was left for the graduate level. As need and room in the undergraduate curriculum for environmental engineering grows, the opportunity now exists to bring undergraduates to a level of theoretical comprehension equivalent to that gained in other disciplines.

The material in the book can be organized in numerous ways depending on the backgrounds of students and the breadth and depth of the environmental engineering curriculum.
