A relationship developed previously to estimate emissions from surface aerated reactors that accounts for both gas and liquid phase mass transfer resistances is extended to reactors with diffused aeration systems. The method accurately predicts the observed emission rate of twenty volatile organic compounds with a wide range of Henry's coefficients over a wide range of hydrodynamic conditions. The liquid‐and gas‐phase mass transfer coefficients are estimated.
