The objectives of this research are:  (1) to study the fluid mechanics          and acoustical nature of gas dispersion in agitated tanks using                 hydrophones to record sound spectra; and (2) to determine the                   relationship between the mass transfer coefficient, kla, and the sound          spectra signatures of the gas dispersion.  Further, the actual                  mechanism of sound production and effects of scale, impeller geometry           and distributor geometry will be investigated and related to the gas            dispersion mechanics.  Standard techniques will be used in the work to          obtain the sound spectra and kla data.  The research is to develop an           online measurement technique to monitor and optimize mass transfer in           aerated, agitated tanks.
