Conclusion
The advantages of aerobic granules formed in SBRs are dense and strong microbial structure, good settling ability,
high biomass retention and ability to withstand a high organic loading rate. Aerobic granules can be used in treating
high-strength wastewaters containing organics and toxic substances. Especially, nitrogen removal and phosphorus
removal are also achieved by using aerobic granules. However, only in SBRs aerobic granulation has been observed.
More studies on the feasibility of developing aerobic granulation in continuous culture systems are need to be
investigated. As compared to anaerobic granules, aerobic granules have relatively low stability because of their fast
growth rate. Therefore, it is required that research for improving the stability of aerobic granules by manipulating
operational conditions or through selecting for slow-growth bacteria.
