Summary:The results of an experimental study to determine the oxygen transfer properties of a 38 mm diameter airlift pump are presented. The effects of varying initial bubble size, flow rate, flow pattern, and water quality on oxygen transfer were examined. Pumping efficiencies of the airlift pump were found to be as high or higher than centrifugal pumps and oxygen transfer efficiencies as high or higher than fine bubble diffuser aeration systems. Generalized predictive equations for oxygen and nitrogen transfer and supersaturation in airlift pumping are presented
