Abstract Methods are presented for simulating the transfer of volatile organic contaminants to the atmosphere during surface and bubble aeration. Suitable values of the input parameters for conditions representative of activated sludge treatment are suggested, and model calculations are presented. The effects of important variables such as oxygen transfer requirement, the solute's Henry coefficient, and the oxygen transfer efficiency are illustrated by the calculations. Transfer of volatile organics to the atmosphere is to predicted to be substantially greater in surface aeration than in bubble aeration for a given oxygen transfer rate under conditions of practical interest. This difference is attributed to greater saturation of the gas phase in bubble aeration, compared to surface aeration. The transfer of organic solutes to the atmosphere in bubble aeration decreases with increasing oxygen transfer efficiency, if the oxygen transfer requirement is held constant, as a consequence of the concomitant decrease in the required air flow rate.
