This chapter briefly reviewed the factors that may influence or involve in aerobic granulation in SBR, such as substrate composition, substrate loading rate, hydrodynamic shear force, feast-famine regime, solids retention time, dissolved oxygen, feeding strategy, cycle time or hydraulic retention time, settling time, exchange ratio, presence of calcium ion in feed, seed sludge, and reactor configuration. It is expected that such information would be useful in designing aerobic granular sludge SBR for wastewater treatment.
