A process for separating a dispersed phase from a continuous phase comprising immersing vertically in the mixed phases an apparatus. (a) an inner cylindrical member comprising an elongated tube having upper and lower ends and a plurality of turbines, which are free to rotate about their longitudinal axis, mounted within the tube, the turbines being spaced apart from one another and so constructed that adjacent turbines have different rotational direction or velocity; (b) optionally, an outer cylindrical member comprising an elongated tube having upper and lower ends and a plurality of openings in the lower half of the tube wall; (c) a base member to which the lower ends of the outer and inner cylindrical members are attached so that the lower ends are sealed, the outer and inner cylindrical members being arranged in a concentric manner; (d) a gas inlet pipe for introducing gas bubbles into the lower end of the apparatus; and (e) a conduit means for removing the liquid from the interior of the inner cylindrical member, pumping a gas into the inner cylindrical member, and removing the continuous phase from the interior and lower end of the inner cylindrical member. The apparatus is useful for aerating sludge, separating the fine particles contained in a slurry, and separating particles having smooth surfaces from particles having jagged surfaces. Problems regarding plugging and tangling of the turbines with foreign materials are eliminated. |
