About the Book
This book is written as the book one wants to read when first starting the study of filtration. This book is intended for the person who has some technical background outside of filtration, and who now wants to “get his feet wet” in this subject This book is also for the “old filtration hand” who, while he has some experience in some special field of filtration, may now want to step back and see a larger view. And it is intended as a vehicle for sorting out and explaining words and phrases that appear in technical and advertising literature. The incentive to write this book comes from the author's experience, as a charter member of ASTM’s Committee F21 on Filtration, as chair of the subcommittee on liquid filtration (for 15 years), and as an instigator of the 1986 symposium on filtration sponsored by ASTM.

About the Author
Peter R. Johnston was trained in chemistly at Miami University, Oxford, Ohio. After serving an Army combat tour in Korea, he began an R&D career in the chemical-process industry, where he designed and operated pilot plants for a variety of chemical processes.
In 1972 he joined Commercial Filters, Lebanon, Indiana, and began con- centrating on the study of filtration. He subsequently moved to Gelman Sciences, Ann Arbor, Michigan, then to Ametek, Sheboygan, Wisconsin. Since 1992, retired from industly, he has lived in Carrboro, North Carolina, serving as a consultant to clients with an assortment of questions.
