Aerobic granulation under the combined hydraulic and loading selection pressures
چکیده انگلیسی

Two SBR reactors were set up to investigate the feasibility of aerobic granulation under the combined selection pressures of hydraulic shear force and substrate loading. Aerobic granulation was studied at superficial upflow air velocity of 3.2 and 2.4 cm/s under an organic loading rate (OLR) range of 6.0–15.0 kg COD/m3 d. Good reactor performance and well granule characteristics were achieved in a wide OLR range from 6.0 high up to 15.0 kg COD/m3 d at 3.2 cm/s. While under the velocity of 2.4 cm/s, stable operation was limited in the OLR range of 6.0–9.0 kg COD/m3 d and failed to operate with granule deterioration under further higher OLRs. The optimal combination of hydrodynamic shear force and loading selection pressure was demonstrated to be an important factor that influence aerobic granulation and govern the granule characteristics and reactor performance.
