The invention relates to a microbial control system for treating influent water and sump water for control of microbial material in machines which process water such as ice making machines, humidifiers such as cool mist humidifiers and cooling towers. The microbial control system includes antimicrobial treatment media housed in a containment vessel. The treatment media can include any one or more of transition metals and transition metal oxides. The transition metal may be any of Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Rf, Db, Sg, Bh, Hs, Mt, Uun, Uuu and Uub. |

1. An ice making machine comprising a containment vessel and ice-forming racks and a pump for supplying water to one or more of the ice-forming racks held at a temperature sufficient to accrete ice as the water passes over the ice forming racks, wherein a microbial control system is present in the containment vessel and wherein the microbial control system comprises antimicrobial treatment media present on a support material wherein the antimicrobial treatment media comprises any of transition metals or transition metal oxides, wherein the transition metal is selected from the group consisting of Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Rf, Db, Sg, Bh, Hs, Mt, Uun, Uuu and Uub, and combinations thereof,
wherein the support material is selected from the group consisting of activated carbon, calcium carbonate, natural coral, alumina, silica, alumino-silicates, magnesium silicates, calcium silicates, titanium oxide, tin oxide, lanthanum oxide, copper oxide, vanadium oxide, manganese oxide, nickel oxide, iron oxide, zinc oxide, zirconium oxide, magnesium oxide, thorium oxide, polyethylene, polypropylene, polyvinylchloride, polystyrene, polyethylene terephthalate and mixtures thereof, and wherein the support material has a pore distribution of about 5% macropores having a size larger than about 1000 Angstroms to about 40% macropores having a size larger than 1000 Angstroms, and about 5% mesopores having a size of 100 Angstroms to 1000 Angstroms to about 50% mesopores having a size of 100 Angstroms to 1000 Angstroms and about 10% micropores having as size of less than 100 Angstroms to about 80% micropores having as size of less than 100 Angstroms and wherein the microbial growth control system controls microbial growth in any of influent water and sump water processed by the ice making machine by contacting the influent water and/or sump water with the antimicrobial treatment media. |
