A mathematical mechanistic model describes both aeration and substrate removal in a sparged packed-bed biofilm reactor. The model describes oxygen transfer by two simultaneous pathways: bulk liquid oxygen dissolution and interfacial oxygen transfer. Substrate removal rate, oxygen utilization rate, dissolved oxygen and substrate concentration profiles, and oxygen transfer efficiency for different air sparging and organic loading conditions were determined by the model simulation. Model simulation results agreed closely with laboratory experimental results over a wide range of aeration and organic loading rate conditions. The close agreement was the result of including the interfacial oxygen transfer pathway in the model.
