Oxygen transfer measurements were carried out in order to compare surface aerators under operating conditions in waste water. A simple method was used without using chemicals like cobalt or sulfite. Results show incomplete mixing of basins at high biological activity that lead to mass transfer data not comparable with data of standardized fresh water tests, but different types of aerators could be compared under local operating conditions as basis for investment decisions.
