    • A system for providing gas-liquid contacting for mass transfer of the gas to the liquid in an upright tank (10). An upright draft tube (20) is mounted within the tank (10) and has a lower end (22) spaced from the tank bottom (16) and an upper end (24) spaced from the liquid surface (12). A plurality of mixing impellers (26, 28, 30, 32) in the draft tube (20) establish a field of agitation to cause shear thinning and upflow through the draft tube (20) and turbulence at the liquid surface (12). A plurality of radially inwardly projecting, circumferentially spaced baffles (38, 40, 42, 44) extend from the draft tube and are proximate to the mixing impellers to prevent swirling within the draft tube. Gas is sparged into the tank (10) adjacent to the lower end (22) of the draft tube (20).

    • A hydrofoil impeller (1) wherein the tip edge (12) is straight and has a right angle with a radius (r) extending from the central axis (x) to the tip edge. In the central hub (4)and in each of the blades (6) the number of holes in each group of first and second holes (5, 8) is at least five. The pattern in which the first holes (5) and second holes (8) are arranged in each of the respective groups of holes is in a form of an ellipse having a center (13) and a major axis (14) which is substantially parallel to the radius (r) and placed at a distance (d) therefrom. The leading edge (10) is, in the direction to rotation, behind an imaginary radial line (T) intersecting the central axis (x) of the shaft (2) and the center (13) of the ellipse, said leading edge (10) being at an angle (α) of 58°± 2° in relation to the radial line (T). The area of the blade (6) is divided into four planar portions (7, 17, 18, 19) by three straight bends (20, 21, 22).

    • A mixing bucket has a cylindrical sidewall with longitudinally separated lower and upper bucket rims defining a bucket interior volume. A laterally oriented bucket bottom spans the sidewall and separates the bucket interior volume into upper and lower bucket volumes. At least one aperture is located in the sidewall and provides substantially laterally oriented access between an ambient environment and the lower bucket volume. At least one laterally oriented channel extends from at least one aperture and is located within the lower bucket volume. An elongate anchoring structure has first and second anchor ends laterally separated by an anchor body. The anchoring structure engages the bucket by the anchor body being at least partially positioned within the channel. An anchoring force is exerted upon the anchoring structure while the anchoring structure is engaged with the bucket, and the anchoring force counteracts a mixing force being exerted upon the bucket.
