Abstract: An external loop inversed fluidized bed airlift bioreactor (EIFBAB) was modified with a mixed-tank reactor placed in series to extend the phenol treatability range. The hydrodynamic characteristics of the modified reactor system were studied to optimize the reactor design and operation. Phenol degradation at high concentrations was investigated at recycle rates from the mixed-tank reactor from 0 to 15L/h under batch operation. With a total working volume of 10L, the new setup could handle 3000mg/L phenol at an enhanced total biodegradation rate of 90mg/h at 5L/h recycle rate, compared to 46mg/h in the original EIFBAB. Continuous operation was ascertained for complete degradation up to 3500mg/L phenol and feed flow rates up to 160mL/h. The recoverability of the system under shock loading of phenol up to 3500mg/L was also assessed.
