ABSTRACT:
A method and apparatus for supplying dissolved gases (such as oxygen, ozone, chlorine etc.) for chemical and biological processes is described. The methods and apparatus described are particularly suitable for use in the biodegradation of organic matter (such as in municipal and industrial wastewater treatment), and other uses. The apparatus may comprise a dissolved gas supply system.
