ABSTRACT:
Self-contained treatment apparatus for a body of water includes a mounting assembly having flotation elements for fixedly supporting a circulation or agitation device below the surface of the water and driving or motor mechanism above the water surface. Actuation of the motor mechanism operates the circulation or agitation device such that naturally occurring oxygen-saturated water near the surface is drawn downwardly and mixed with the lower oxygen deficient reaches of the body of water and effecting a net increase in dissolved oxygen content. Optionally, actuation of the motor mechanism operates a bubble generator adjacent the water surface so that the air bubbles generated are drawn down with the oxygen-saturated surface water, where oxygen from the bubbles dissolves into the surrounding oxygen-deficient water, thus accelerating the improvement in dissolved oxygen content. Additionally, structure may be included for selective directional control of the oxygen-enriched discharge stream, so that a gentle flushing action can be applied against nutrient-rich sediments, sludges or residues accumulating on the bottom, thereby further improving the water quality.
