ABSTRACT:
The method of treatment of a body or bodies of liquid, that is essentially aqueous, and containing other components, the method including introducing O2molecules into said liquid body or bodies to increase dispersed or dissolved oxygen content of the liquid, and allowing at least some of the dispersed or dissolved O2to sink in the body of liquid for retention and treatment of said other components. A submerged venturi is preferably used to entrain air in a stream of such liquid, sub-micron oxygen being formed and dispersed.
