Abstract
A waste pond liquid circulator is described in which a plurality of pontoons extend substantially radially from a base and with respect to a central axis passing through the base. A drive mechanism is mounted on the base that is drivingly connected to an impeller for rotating the impeller about the central axis. The base and pontoons are configured to rest on a liquid surface with the pontoons engaging the liquid and forming wedge shaped spaces between successive pontoons. The impeller is rotated by the drive mechanism about the central axis to produce a vortex current of liquid directed toward the it base. The pontoons are configured to receive and direct the current substantially radially away from the base through the wedge shaped spaces.
