<p>A method and apparatus for aerating a liquid wherein the liquid to be treated is drawn down a vertical pipe at a predetermined velocity to entrain air bubbles into the moving liquid forming an air liquid mixture, maintaining the air bubbles in liquid contact for a minimum period under increasing hydrostatic pressure to dissolve the air and returning the aerated liquid to the reactor, the air bubbles being generated close to the surface of the liquid above the inlet of the vertical pipe.</p> |
