Abstract
To introduce and mix fluids, particularly gas (air) with liquid, which is called sparging, an airfoil blade impeller is used for pumping the liquid and for introducing the fluid to be sparged into the liquid through holes in the suction surface of the blade. The airfoil blades are characterized by camber, thickness and location of holes which result in high stripping efficiency of the gas into the liquid without significant decrease in power use efficiency over conventional sparging systems.
