Abstract: The method of treatment of a body or bodies of liquid, that is essentially aqueous, and containing other components, the method including introducing O2 molecules 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 O2 to 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.

Abstract: An alarm and pump control system for automatic chlorinators of the type used with septic treatment systems is disclosed. The present invention includes a switch module that couples alongside an automatic chlorinator that uses dissolvable standard size chlorine tablets in a stack and an activator module that sits on top of the stack of chlorine tablets and descends as the chlorine tablets dissolve. The switch module includes proximity switches that can be coupled to one or more alarms. The activator module includes one or more magnets that interact with the proximity switches to signal the owner that the chlorinator requires refilling or to cut off the pump power.
