  • Patent number: 11351491
    Abstract: A filter media having lignite-derived activated carbon, polyacrylic acid (PAA), a commercially available copper-zinc alloy, and polydiallyldimethylammonium chloride (PolyDADMAC) or Luviquat®, which is Poly[(3-methyl-1-vinylimidazolium chloride)-co-(1-vinylpyrrolidone)], combined and used as suitable replacement for TOG bituminous coal-based activated carbon, silver, and PolyDADMAC. Functional groups in lignite-based activated carbon interact with the polyacrylic acid. Functional groups such as calcium, iron, or aluminum oxide/hydroxide of lignite-based activated carbon interact with PAA, and help hold the PolyDADMAC in place. The additional presence of a copper-zinc alloy enhances the filter anti-microbiological performance.

  • Patent number: 9718013
    Abstract: A method for forming and immobilizing small particles on a filter substrate using a first and second polymer solution, a solution of sodium bromide and a solution of a metal salt. The method adjusts the pH of at least one of the first and second polymer solutions, immersing the filter substrate in the first polymer solution and immersing the filter substrate in the second polymer solution. The method includes repeating the steps of immersing the filter substrate in the first solution and the second solution alternately until desired number of layers is achieved. The method allows for the filter substrate to be immersed in the solution of the metal salt and subsequently in the solution of sodium bromide.

  • Patent number: 9289702
    Abstract: Water filtration media having a charged material affixed directly to binder material used in the fabrication of the filter media. A microbiological interception enhancing agent is added to the binder directly. The media having a charged material and a microbiological interception enhancing agent both affixed directly on or in a binder material is then combined with core filter media and prepared as a filtration media. A filter is prepared from the treated filter media.
