20090200246ION enhancement - 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 a N-halohydantoin compound for releasing the N-halohydantoin compound when contacted by the body of water with the at least one N-halohydantoin having the formula:08-13-2009
20090272698Bromate suppression - A apparatus and method for killing microorganisms in a body of water that has been treated with ozone in the presence of bromide ions with the method comprising the steps of carrying out the ozonization of a body of water in the presence of bromide ions, adding a metal ion donor to the body of water, and adding a hypobromite ion scavenger to the body of water to interact with the metal ion donor to enhance a metal ion concentration in the body of water while suppressing the oxidization of the bromide by the Ozone to produce bromate.11-05-2009
20100140185Wastewater treatment - An antimicrobial method of treating wastewater and a wastewater antimicrobial dispenser containing an antimicrobial agent for treating a body of wastewater to kill microorganisms by increasing the concentration metal ions therein. The antimicrobial method includes the step of increasing the effectiveness of the biocidal component in the body of wastewater to thereby lessen the need for a supplemental biocide by adding a compound containing a hydantoin ring where the compound containing a hydantoin ring may or may not have any antimicrobial properties. The antimicrobial agent including a source of biocidal metal ions and a compound containing a hydantoin ring where the antimicrobial agent may be a powder, a liquid a solid or combinations thereof.06-10-2010
20100143427Antimicrobial Surfaces - An antimicrobial structure surface therein wherein the structure surface includes an antimicrobial agent having a biocidal metal ion source and compound containing a hydantoin ring wherein the compound containing the hydantoin ring may or may not have antibacterial properties but the combination of the compound containing the hydantoin ring and the biocidal metal ion source when in the presence of a liquid coact to increase the level of available metal ions for killing microorganisms on the structure surface.06-10-2010
20100143430Antimicrobial agents - An antimicrobial agent to kill microorganisms by enhancing the concentration of metal ions through use of compound containing a hydantoin ring in the presence of a liquid. The method includes the step of to enhancing the effectiveness of the biocidal component to lessen the need for a supplemental biocide wherein the antimicrobial agent may be in an active state i.e. liquid or an inactive state i.e. solid, tablet, powder, granular form or combinations thereof. The apparatus includes a dispenser containing an antimicrobial agent in either an active state or an inactive state with the antimicrobial agent comprising a compound containing a hydantoin ring and a source of biocidal metals ions for delivery of the antimicrobial agent to a site of microorganisms.06-10-2010
20100143495Antimicrobial body affecting products - A method and apparatus for control the growth of microorganisms by enhancing the concentration metal ions therein. The method includes the step of to enhancing the effectiveness of an antimicrobial agent having a source of metal ions by adding a compound containing a hydantoin ring to the antimicrobial agent.06-10-2010
20100230365Water treatment - A system and method for maintaining a body of water in a sanitized condition with use of a halogen and a source of silver ions wherein the halogen is maintained at 50% to 75% less than a recommended halogen level for maintaining the body of water in a sanitized condition by adding a compound containing a hydantoin ring to a recreational body of water containing a halogen and a source of metal ions.09-16-2010
20110094972Water treatment - A sanitizing agent for maintaining a biocidal effective bacteria count in a body of water comprising a metal ion donor for donating a metal ion and a compound containing a hydantoin ring with the combination of the compound containing the hydantoin ring with the metal ion donor enhancing the effectiveness of the sanitizing agent to enable the sanitizing agent to maintain a biocidal effective bacteria count in the body of water.04-28-2011
