Abstract
A turbine, adaptable to enhance the levels of dissolved gas such as oxygen in water flowing therethrough, includes a rotating shaft and a runner secured to the shaft. The runner includes a crown, a band and a plurality of spaced apart runner blades. Each blade has a water directing surface defined by a pressure side, an oppositely facing suction side, a leading edge and a spaced apart trailing edge. At least one of the blades further has a first gas admission passage extending from a first gas admission aperture formed in the crown to a second gas admission aperture formed in the band. The runner further includes an interconnection passage and a gas discharge aperture formed in the band for discharging an oxygen containing gas from the band.
