Abstract
Disclosed is a method and apparatus for producing gas bubbles of a uniform ize in a liquid. First, the liquid medium flows over a wall or other liquid containment surface. Gas is then emitted into the liquid medium to form gas bubbles from an aperture in the wall at a bubble formation position. A standing wave is then established in the liquid medium at the aperture. It is found that the bubbles formed at the aperture are of a substantially uniform size.
