Aeration of Hydro Releases at Ft. Patrick Henry Dam
A method has been developed for increasing dissolved oxygen concentrations in the turbine releases from hydroelectric power plants. A systematic procedure was used for evaluating promising solutions to low DO concentrations. The method selected for development at Fort Patrick Henry Dam was oxygen injection by use of small pore diffusers located upstream from the turbine intakes. Laboratory tests were conducted on commercially available, fine-pore diffusers to select those diffusers worthy of field testing. Laboratory tests included determination of bubble sizes and oxygen transfer efficiency. Field tests for oxygen transfer efficiency were performed for two different diffusers. Additional tests were performed to assess the effect of spacing between diffusers on oxygen transfer efficiency.
