Simplified transient model of an upflow cocurrent packed bed bioreactor
A dynamic model incorporating biomass growth and liquid hold-up evolution is developed to describe a fixed bed bioreactor operation with cocurrent upflow of water and air flows. The model permits to predict cycle time and optimal operation conditions for high substrate removal and long cycle times. Simulation results are compared with published experimental results and show good model accuracy.
