Title: Wind-powered impeller-mixer

Patent ·
OSTI ID:5777713

The invention is an energy-saving means for providing turbulence as well as circulation to liquids in a controlled natural purification system for advanced waste water treatment and algae farming. The wind-powered impeller-mixers are used in the algae growing reactors of a controlled natural purification system. The invention consists of a vertical vane type windmill that turns an impeller blade to cause turbulence in waste water being treated. The impeller blade may be geared to operate from a horizontal position to a vertical position to provide circulation movement. A motor-generator hook-up is combined with windmill-impeller system so that generated energy may be stored for use in turning the impeller blade when there is no wind or not enough wind to operate the system. A clutch arrangement is used to disengage the impeller when the algae growing reactor is to be drained.
