Anaerobic Granulation and Granular Sludge Reactor Systems

Advanced anaerobic processes integrating granular sludge are emerging technologies for efficient wastewater treatment. As a result of increasing acceptance toward the anaerobic granular processes, a growing interest in the technology has resulted in a remarkable increase of full-scale plants installed worldwide over the last three decades. While the technology is well accepted and much research work had been conducted on granule formation, insight unfolding the granulation remains unclear. This chapter presents a review of literature documenting theoretical elucidations on anaerobic granulation and recent advances in granulation research with hydrogen production. Applications of anaerobic granulation in various reactor systems and the future trend are also outlined.
