Water and Wastewater Technology

This book provides comprehensive coverage of the fundamental principles and current practices in water processing, water distribution, wastewater collection, wastewater treatment, sludge processing, advanced wastewater treatment, and water reuse. The objective is to transfer knowledge of these subjects to persons interested in continuing their study in sanitary technology and engineering, and to persons interested in operation and maintenance of water and wastewater facilities. This fifth edition updates the subject matter, illustrations, and problems to incorporate new concepts and issues related to the water environment. In this edition, the revision of text and addition of new problems are in the introductory chapters on chemistry, biology, hydraulics and hydrology, and water quality and the final chapters on operation of wastewater systems, advanced wastewater treatment, and water reuse. Previous text and problems for Chapters 6-11 are unchanged. Based on our experience in education, we believe students benefit from a review of the disciplines that have specific applications in water supply and wastewater management. Therefore, the introductory chapters cover fundamentals of chemistry, biology, hydraulics, and hydrology applicable to sanitary studies. The subject of water quality is also introductory to understand the reasons for the selection of processes in water and wastewater treatment. In presenting water supply and wastewater management, the approach is traditional, covering water distribution, processing, and operation of systems separated from wastewater collection, treatment, and operation. We have carefully integrated the subject matter in each area so readers can clearly understand the interrelationships between individual unit operations and integration of systems as a whole. The final chapters on advanced wastewater treatment and water reuse are increasingly important in many regions for pollution control and beneficial use of water resources. Extensive use of illustrations increases the understanding of concepts and shows modern equipment and facilities. Also, numerous sample calculations assist the reader in the application of equations, charts, and tabulated data. Answers are given for some of the homework problems, mainly to help persons interested in individual study. A discussion of the book's contents is given in Chapter 1, Introduction. We hope this book will be of benefit to both present and future colleagues who teach, study, and practice in the area of the water environment. Mark J. Hammer Mark J.
