Abstract
A method and apparatus for treating a body of water to kill microorganisms by enhancing the concentration metal ions therein. The apparatus comprising a dispenser with a first housing having a water accessible compartment containing a source of 5,5-dimethylhydantoin for releasing the 5,5-dimethylhydantoin when contacted by the body of water and a second housing having a water accessible compartment containing an insoluble metal ion donor for releasing metal ions when contacted by the body of water containing the 5,5-dimethylhydantoin
Claims22
A method of treating a body of water to kill microorganisms by enhancing the concentration metal ions comprising:
- adding silver salt to the body of water;
- and
- adding 5,5-dimethylhydantoin to the body of water to interact with the silver salt to enhance a silver ion concentration in the body of water.
A method of treating a body of water to kill microorganisms by enhancing the concentration of metal ions comprising:
- adding a source of metal ions to the body of water to generate metal ions in the body of water;
- and
- adding 5,5-dimethylhydantoin to the body of water to enhance the metal ion concentration in the body of water to thereby lessen the need for a supplemental biocide.
A dispenser for killing microorganisms in a body of water comprising:
- a first housing having a water accessible compartment containing a source of 5,5-dimethylhydantoin for releasing the 5,5-dimethylhydantoin when contacted by the body of water;
- and
- a second housing having a water accessible compartment containing a metal ion donor for releasing metal ions when contacted by the body of water containing the 5,5-dimethylhydantoin.
A dispenser for killing microorganisms in a body of water comprising;
- a first housing having a water accessible compartment containing a metal ion donor for releasing metal ions into the body of water when contacted by the body of water;
- and
- a second housing having a water accessible compartment containing a source of unhalogenated hydantoin for releasing the unhalogenated hydantoin when contacted by the body of water containing metal ions to maintain a higher metal ion level in the body of water in killing microorganisms than if metal ions were used alone in killing microorganisms in the body of water.
A fluid for recreational use comprising:
- a body of water;
- and
- a source of silver and 5,5-dimethylhydantoin in tablet form with the 5,5-dimethylhydantoin and the source of silver cooperating to maintain a level of silver ions present to sustain a standard plate count of less than 200 colonies per milliliter at 35 degrees F.
