Abstract

Biogranulation has been studied widely and successfully industrialized for the last two decades. Biogranulation

technology for wastewater treatment includes anaerobic and aerobic granulation processes. Even though anaerobic

granulation has been relatively well studied and known, studies on aerobic granulation have begun recently. The

aerobic granular sludge is known to have denser and stronger microbial structure. It has regular, smooth round shape,

and a clear outer surface, while conventional activated sludge flocs is loose, fluffy, and irregular. Since formation

and characteristics of aerobic granulation are affected by many factors. Studying the models of aerobic granulation,

major factors affecting aerobic granulation, characteristics of aerobic granules, microbial structure and diversity, and

their industrial applications are important for a comprehensive understanding of aerobic granulation.
