Citric acid and a water-soluble binding polymer are added to a volume of water. The intermediate solution is circulated past an ion generator for a predetermined time period, and copper ions generated thereby are bound by the binding polymer and/or chelated by the citric acid. Once a desired concentration of copper ions has been achieved, the concentrated solution is stored in portable vessels for transport to the remote water volume. Concentrated solution is added to the remote water volume to achieve a concentration therein of approximately 0.2-0.3 ppm.Type: GrantFiled: November 16, 2010Date of Patent: December 16, 2014Inventor: George Loucaides

Publication number: 20140356406Abstract: Described herein are glass or glass-ceramic articles having improved antimicrobial efficacy. Further described are methods of making and using the improved articles. The improved articles generally include a glass or glass-ceramic substrate, a compressive stress layer that extends inward from a surface of the glass or glass-ceramic substrate to a first depth therein, and an antimicrobial agent-containing region that extends inward from the surface of the glass or glass-ceramic substrate to a second depth therein. The antimicrobial agent-containing region may include at least one of a plurality of ion exchanged-copper ions and a plurality of ion exchanged-silver ions, arranged in a predetermined portion of the surface.Type: ApplicationFiled: May 20, 2014Publication date: December 4, 2014Applicant: CORNING INCORPORATEDInventors: Mallanagouda Dyamanagouda Patil, Christine Coulter Wolcott

Publication number: 20140356454Abstract: An antibacterial wound dressing is based on or derived from gel-forming fibres such as carboxymethyl cellulose or alginate fibres having silver ions linked thereto at some but not all of the exchangeable sites such that the distribution of silver ions over the exchangeable sites is substantially uniform. The silvered fibres for the wound dressing can be prepared by contacting an assembly of precursor gel-forming fibres having exchangeable sites under conditions which do not cause irreversible gelling of the fibres with an amount of a solution containing silver ions so as to link silver ions at some but not all of the exchangeable sites, the whole of the assembly of precursor gel-forming fibres being contacted essentially simultaneously with the entire solution containing silver ions.Type: ApplicationFiled: August 4, 2014Publication date: December 4, 2014Inventor: Roger Bray
