ABSTRACT:
An impeller for mixing includes a disk having substantially identical top and bottom surfaces, opposed and spaced apart from each other and including a plurality of holes extending through the disk and arranged symmetrically around a circle having a smaller diameter than the disk. A first set of troughs, corresponding to a number of the plurality of holes, each trough having a portion having a width corresponding substantially to a width of the holes, is arranged on the top surface of the disk and each trough slopes downwardly from a periphery of the disk toward each of the holes, respectively. A second set of troughs, corresponding to a number of said plurality of holes, each trough having a portion having a width corresponding substantially to a width of the holes, is arranged on the bottom surface of the disk and each trough slopes upwardly from a periphery of the disk toward each of the holes, respectively.
