Pressure swing contactor for the treatment of a liquid with gas

摘要

A residential method for treating water with an ozidizing gas operates under elevated pressure. The elevated pressure is obtained by means of a pressurized oxidizing gas source (e.g. an air pump) or a prandtl layer turbine. The elevated pressure of the treated water is optionally used to dispense the treated water. The prandtl layer turbine may be used to obtain particularly fine bubbles of a gas (e.g. bubbles from about 1 mu to about 20 mu in diameter) in a liquid.
