Patent Images
1. A system for recovering energy while treating a body of wastewater, the system comprising:
- a tank, the tank containing the body of wastewater;
a plurality of diffusers, the plurality of diffusers immersed in the body of wastewater and operative to create motion therein by a discharge of bubbles;
a propeller, the propeller immersed in the body of wastewater and operative to spin in response to the motion in the body of wastewater; and
a generator, the generator linked to the propeller and operative to generate electrical energy in response to the spinning of the propeller.

Abstract
A system for recovering energy while treating a body of wastewater comprises a tank, a plurality of diffusers, a propeller, and a generator. The tank contains the body of wastewater. The plurality of diffusers is immersed in the body of wastewater and is operative to create motion therein by the discharge of bubbles. The propeller is immersed in the body of wastewater and is operative to spin in response to the motion in the body of wastewater. The generator is linked to the propeller and is operative to generate electrical energy in response to the spinning of the propeller.

14. A method for recovering energy while treating a body of wastewater, the method comprising the steps of:
-
placing the body of wastewater in a tank; immersing a plurality of diffusers in the body of wastewater and causing the plurality of diffusers to create motion in the body of wastewater by a discharge of bubbles; immersing a propeller in the body of wastewater and causing the propeller to spin in response to the motion in the body of wastewater; and linking a generator to the propeller and causing the generator to generate electrical energy in response to the spinning of the propeller. - View Dependent Claims (15, 16, 17, 18, 19, 20)
