Abstract

A large two blade paddle impeller GD220 was developed for aeration agitation, and its performances were evaluated by measuring the power consumption, mixing time, and aeration power consumption. The mixing performance was equivalent to that of similar large paddle MR203. In addition, the impeller blade tips were retracted and provided with cutouts, which made it difficult to form cavities during aeration, and the aerated power consumption was not reduced much.
