Energy recovery during wastewater treatment

摘要

A system for recovering energy while treating a body of wastewater comprises a tank 110, a plurality of diffusers 150, a propeller 170, and a generator 190. The tank 110 contains the body of wastewater. The plurality of diffusers 150 is immersed in the body of wastewater and is operative to create motion therein by the discharge of bubbles. The propeller 170 is immersed in the body of wastewater and is operative to spin in response to the motion in the body of wastewater. The generator 190 is linked to the propeller 170 and is operative to generate electrical energy in response to the spinning of the propeller 170.
