Start-up, steady state performance and kinetic evaluation of a thermophilic integrated anaerobic-aerobic bioreactor (IAAB)

► Kinetic analysis of IAAB under thermophilic condition was conducted for the first time. ► Maximum applicable OLR of IAAB was at 28.0 g COD/L day. ► Monod and Grau second-order model are best-suited for thermophilic IAAB.
