Tims Ford Dam located on the Elk River in middle Tennessee is a multipurpose project of the Tennessee Valley Authority (TVA) which provides flood control, water supply, and hydropower generation. Because of thermal stratification in the reservoir and biochemical processes, the hydroturbine discharges from Tims Ford have been historically low in dissolved oxygen (DO) content during several months of the year. To increase the DO of these discharges to a concentration level of 6 mg/L, a dual aeration system using both air injection into the turbine and oxygen injection through porous hoses in the turbine penstock has been installed. This paper describes the air and oxygen systems and presents the results of aeration system operation on DO and total dissolved gas in the turbine discharge and on hydroturbine efficiency.
