Wastewater Purification Aerobic Granulation in Sequencing Batch Reactors

Over the past decade, extensive research has been dedicated to the development of aerobic granulation technology for high-efficiency wastewater treatment. Taking a systematic approach, Wastewater Purification provides a comprehensive understanding of aerobic granulation in sequencing batch reactors by presenting fundamental principles of aerobic granulation along with the basics of process operation under various conditions. The book explains what aerobic granules are and how they form, discusses the key factors that influence aerobic granulation, addresses commonly encountered problems, and offers ways to improve process stability. It also outlines directions for future research.

A newcomer to the scene, aerobic granulation is on its way to becoming the hot new technology for high-efficiency wastewater treatment. Thus far, intensive research has been conducted with regard to the understanding of the mechanism of aerobic granulation in sequencing batch reactors (SBR) and its application in treating a wide variety of municipal and industrial wastewater. This basic research has promoted the technology from laboratory-study all the way to the present pilot- and full-scale application. The time is right for a reference that discusses the technology and its application in wastewater purification. Wastewater Purification: Aerobic Granulation in Sequencing Batch Reactors discusses state-of-the-art research and application of this environmental biotechnology tailored to enhanced wastewater purification. The seventeen chapters provide a systematic and comprehensive understanding of aerobic granulation in SBR by incorporating fundamental principles of aerobic granulation with the basis of process operation under various conditions. The book clearly explains what aerobic granules are and how they form. It elucidates key factors that influence aerobic granulation and addresses common problems encountered and their solutions. This is the first book-length exploration of aerobic granulation. Other books that cover it are smaller, less comprehensive, less in depth, and less up to date. This book provides first-hand information derived from the authors’ research and presents a newly-developed theory for aerobic granulation that offers a deep understanding into the essence of current aerobic granulation technology. Using this book as a platform, the technology can be developed further and quickly applied in the wastewater treatment industry.
