Abstract
Procedure for dispersing gas, for example air, in a liquid or slurry that is in motion, characterized in that the total pressure applied by the liquid to the dispersion surface is substantially equal to at least the majority of the surface by compensation for the change in the hydrostatic pressure applied to the dispersion surface and increasing along with the depth, for the dynamic pressure produced by the movement of the liquid and in which the value is made to change in the desired way along with the depth by changing the speed of circulation and the configuration of the space of the same.
