Aerobic granulation is a novel biological technology for the treatment of a wide spectrum of wastewater. It owns several benefits, such as dense and compact microbial structure, good settling capability, high biomass retention etc., when compared with conventional activated sludge. Extensive research efforts have been made to develop aerobic granules in sequencing batch reactor (SBR) for the efficient degradation of various pollutants. However, the mechanisms of aerobic granulation are still unclear, especially with respect to the microbial driving force. Therefore, the present work aims to address the potential role of cell-cell aggregating interactions as a microbial driving force to accelerate the formation of aerobic granules, to improve the SBR performance, and to maintain the integrity of aerobic granules.
