This is the first granulation study except Ferguson [Ferguson LN. Anaerobic codigestion of aircraft deicing fluid and microaerobic studies. M.S. Thesis. Milwaukee, WI, USA: Marquette University; 1999] to develop coupled granules by using a mixture of suspended anaerobic and aerobic cultures exposed to alternating cyclic anaerobic/microaerobic/aerobic conditions. Coupled granules with median sizes of 1.28–1.86 mm and settling velocities of 31–39 m/h were developed, which were comparable to those of both anaerobic and aerobic granules. Coupled granules displayed noteworthy specific methanogenic activity (SMA) and specific oxygen uptake rate (SOUR) as 14–42 mL CH4/g VSS h and 6–47 mg DO/g VSS h, respectively, indicating that they were composed of both anaerobic and aerobic cultures.
