ABSTRACT:
A method of aerating a liquid comprising the steps of providing a column, introducing liquid under pressure into an upper zone of the column in the form of a jet of liquid directed in a path, permitting gas to be entrained by the jet of liquid, obstructing the path of the jet of liquid to form a zone of turbulence in which bubbles are formed in the liquid to create a foam or froth bed in the column, and removing the foam or froth.
