By using lauryl alcohol sulfate as a surface active agent, the effect of the substance on the oxygen transfer rate in bubble aeration was studied experimentally. It was found that the value of the liquid film coefficient in bubble aeration was reduced by the addition of a small amount of lauryl alcohol, sulfate, of less than 100 ppm, to about one-fourth of that which could be obtained in the case without the surfactant. Thie degree of increase of resistance of oxygen transfer was not ascribed directly to the increase of diffusional resistance due to the adsorption of the substance at the air-liqid interface, but principally to a sort of calming actions of lauryl alcohol sulfate against oscillation as well as other complicated motions of bubble surfaces in aeration.
