This article is an evaluation of an impeller which improves mixing efficiency, thereby reducing capital and operating costs. Designed with contoured blades shaped like airplane wings, the impeller provides a significantly increased axial flow component as compared to a conventional flat bladed axial flow turbine impeller. This strong downward flow not only improves mixing and/or reduces power consumption, but also allows the impeller to be positioned higher above the tank bottom. Developed by using lasers to measure flow patterns in test vessels, the impeller concentrates its flow component, up to 70% more mixing is achieved at the same power input. To achieve process results equivalent to that of a conventional axial flow turbine, use of this impeller reduces power consumption by 50%. This provides not only energy savings, bur reduces the size and capital cost of motors and agitator drive systems.
