1. A mixing system for mixing a liquid, comprising:
a first impeller segment comprising a first mount and a first mixing blade of the first impeller segment secured to the first mount;
a second impeller segment comprising a second mount and a first mixing blade of the second impeller segment secured to the second mount, the second impeller segment being separate and discrete from the first impeller segment;
a third impeller segment comprising a third mount and a first mixing blade of the third impeller segment, the third impeller segment being separate and discrete from the first impeller segment and the second impeller segment; and
means secured directly to the mount of the first impeller segment, the mount of the second impeller segment, and the mount of the third impeller segment for concurrently rotating the first impeller segment, the second impeller segment, and the third impeller segment about a rotational axis,
wherein the first impeller segment, the second impeller segment, and the third impeller segment are secured to the means for concurrently rotating so that a plane extending normal to the rotational axis intersects with the first mixing blade of the first impeller segment, the first mixing blade of the second impeller segment, and the first mixing blade of the third impeller segment,
wherein the first mount, the second mount, and the third mount each comprise an opening through which the rotational means passes.
