The oxygen transfer rates and the oxygen transfer efficiencies of different types of aerators were studied in lakes, and the number of diffusers required for hypolimnion aeration was determined. The types of aerators included a cylindrical stone diffuser, a spherical stone diffuser, and 2 ceramic diffusers which differed in pore size. The oxygen transfer rates and efficiencies of the ceramic diffusers were greater than those of the stone diffusers. For a given type of diffuser, a higher transfer rate was generated with pure oxygen than with air. Hypolimnion aeration of Bray's Lake, Missouri, was feasible using the diffusers studied.
