A numerical simulation model is developed in order to predict BOD removal rate in streams on the basis of mass transfer and biochemical reaction kinetics. The double layer model of a flat aerobic and anaerobic bacterial film applies to BOD and DO balances in a stream. A relationship which relates energy dissipation, BOD and DO concentrations in streams and surface area available for attached biomass to the BOD removal rate per unit area is proposed. The different oxygen consumption rates observed in actual streams can be explained by using the model proposed here.
