Sludge/Sludge

Man. on Causes/Control of AS Bulking, Foaming, Other Solids Seperation Problems

• Discussion of the mechanisms of bioflocculation involved in the formation of activated sludge flocs
• Many new case histories of the practical diagnosis and resolution of activated sludge solids separation problems
• Reexamination of the filament backbone concept of floc structure, with additional focus on strong flocs that are devoid of filamentous organisms
• Analysis of bulking and foaming caused by nocardioform organisms and Microthrix parvicella, with emphasis on their origins and control methods
• New photographs and descriptions of filamentous organisms responsible for bulking and foaming
• Results of recent studies of activated sludge and previously unknown microorganisms--and the potential use of molecular biological tools in diagnosing bulking and foaming problems.
• The most common activated sludge operating problems causing poor plant performance are related to solids separation. Especially common are bulking and foaming. Without a proper scientific foundation to support the efforts of wastewater treatment plant management, many attempts to thwart bulking and foaming have failed.
• Manual on Solving Activated Sludge Bulking, Foaming, and Other Solids Separation Problems provides the critical scientific and practical underpinnings needed to understand and combat these problems.
• The third edition of this flagship text is a comprehensive, concise guide to the microbiological and technical aspects of controlling all types of solid separation problems.
• The scientific theory is applied to real-world scenarios, greatly increasing the number of real-world examples of successful control methods. New information is also included on filamentous organism growth and its application in the control of sludge bulking and foaming.
• Now plant operators, regulators and wastewater engineers have a complete guide for battling these formidable design and operating problems.
