Publication number: 20220249993Abstract: A single sheet water filter media for gravity filtration applications that improves flow performance over the product life while maintaining sufficient metal reduction, wherein at least two distinct density gradients of the single sheet form a physical barrier for capturing colloidal and insoluble contaminants, retaining the colloidal and insoluble contaminants until the contaminants become soluble in the fluid, and being removed by the single sheet filter media. The single sheet filter overcomes the difficulties of dual- and multi-layer filters attributable to slower flow rate realized well before the rated lifetime of the product. The two distinct density gradients of the single sheet filter media are created by exerting a force on a liquid slurry, such force resulting in the separation of higher powder loading and fibers that compose the top and bottom density gradients, respectfully.Type: ApplicationFiled: April 27, 2022Publication date: August 11, 2022Inventors: William Li, Frank A. Brigano, Blake E. Savoy, Christopher Thibeault

Patent number: 11351491Abstract: 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.Type: GrantFiled: October 30, 2019Date of Patent: June 7, 2022Assignee: KX Technologies LLCInventors: Jinwen Wang, Meedia Kareem, Rezan Kareem, William Li, Bruce E.

Patent number: 10035089Abstract: The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.Type: GrantFiled: April 4, 2016Date of Patent: July 31, 2018Assignee: KX Technologies LLCInventors: Michael J. Sherman, Lori Foix, Steven J. Haehn, Erik R. Klimpel, David William Fisher, David T. Bardwell, Steven K. Wilson, James B. Larson, Stephen P. Huda, Frank A. Brigano

Patent number: 9718013Abstract: 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.Type: GrantFiled: February 27, 2012Date of Patent: August 1, 2017Assignee: KX Technologies LLCInventors: Jinwen Wang, Meedia A.

Patent number: 9289702Abstract: 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.Type: GrantFiled: November 26, 2013Date of Patent: March 22, 2016Assignee: KX TECHNOLOGIES, LLCInventors: Jinwen Wang, Meedia A. Kareem, Andrew W.

Publication number: 20160059155Abstract: A carafe filter cartridge for reverse flow applications where the filter housing and filter media top end cap directs unfiltered fluid into the filter media annular cavity, through the filter media sidewalls. And the filter media bottom end cap prohibits egress, filter fluid from exiting through the filter media end or the annular cavity. Filtered fluid is instead directed out through apertures in the filter housing sidewall. The optimum ratio of annular cavity and/or top end cap orifice area to the respective perimeter is determined to remove the risk of detrimental fluid flow due to air bubble generation.Type: ApplicationFiled: August 31, 2015Publication date: March 3, 2016Inventors: Andrew W. Lombardo, Stephen P. Huda, Frank A. Brigano
