Abstract
A method for the treatment of pool water with ozone at concentrations less than previously employed. Ozonation, as described herein, provides several distinct advantages including but not limited to inactivation of Cryptosporidium and other water borne microorganisms, reduction of combined chlorine concentrations and oxidation of chloramines.
Claims5
A method of using ozone to inactivate pool water microorganisms, said method comprising:
- providing a pool filtration system with a total filtration flow volume, said system including a contact vessel and a filter downstream therefrom;
- diverting a partial volume of water from said filtration flow volume;
- introducing ozone to said partial filtration flow volume prior to contact with said vessel, said water volume reduced to between about 1% and about 99% of said filtration volume, and said ozone introduced at a concentration up to about the saturation point of ozone in said reduced water volume;
- contacting said reduced water volume for a time with said ozone concentration;
- and
- recombining said contacted, reduced water volume with said filtration flow volume.
