Abstract
A method for suspending settled solids in a liquid using a mixing assembly having a mixing vessel, draft tube disposed within the mixing vessel and an impeller disposed within the draft tube. The method includes rotating the impeller in a first rotational direction for a first period of time so as to cause the liquid to flow in a first axial direction. The method also includes rotating the impeller in a second rotational direction so as to cause the liquid to flow in a second axial direction opposite the first axial direction.
