Fundamental and application of aerobic granulation technology for wastewater treatment
نویسنده
چکیده
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.

Understanding the relationship between microbial community and mechanism of aerobic granulation could enable wider applications of granules for high-strength wastewater treatment. The majority of granulation studies principally determine the engineering aspects of granules formation with little emphasis on the microbial diversity. In this study, three identical reactors namely R1, R2 and R3 wer...
