Activated Sludge: Theory and PracticeActivated sludge is the most widely used biological wastewater treatment process in the world, both for domestic and industrial purposes. This book reviews the major theoretical concepts and practical operational factors, and describes the complexities inherent in the process, which depends on a dense microbial population mixed in wastewater under specific aerobic conditions. It is an ideal reference source for scientists, and a useful troubleshooting guide for practicing engineers and plant operators. |
