Structural Characteristics of Aerobic Granular Sludge and Factors That Influence Its Stability: A Mini Review

Current extensive research on aerobic granular sludge (AGS) largely focuses improving its microbial biodiversity, settlement behavior, nitrogen and phosphorus removal efficiency, shock load resistance. Great challenges that have to be faced are the bottleneck of slow-speed granulation easy disintegration after granulation, which key extended application AGS technology. In present review, typical morphological structures firstly summarized as well model hypotheses, then, we analyze dominant microflora their spatial distribution features. The influencing factors particle structure stability discussed thereafter a macro micro scale. Prospects future trends also based current study results for
