Abstract

To determine the oxygen transfer efficiency of an aerator in clean water the following procedure is used. Residual dissolved oxygen is removed from the liquid by adding sodium sulphite and a catalyst (cobalt chloride). Aeration is started and the rate of oxygenation of the liquid is measured by recording the DO at regular intervals. The oxygen transfer coefficient (KLa) may then be determined. The oxygen transfer coefficient is affected by the following factors: temperature: mixing intensity, tank geometry and characteristics of the water.

Key Words   
oxygen transfer, air supply, aeration equipment, diffuser, DO, KLa
