Patent number: 11583846Abstract: An alumina-based adsorbent and method of making exhibiting high affinity and capacity towards cations and oxyanions in a broad pH range and presence of large excess of competitive ions. Alumina based adsorbent is a mixed oxide of alumina existing in tetra-, penta-, and octahedral coordination at specific ratio, and oxides of polyvalent metals of elements titanium, zirconium, tin, cerium, lanthanum, iron, or combinations thereof. The alumina-based adsorbent may be used for selective removal of oxyanions of fluoride, phosphorus, arsenic, chromium, and/or selenium, and/or cations of lead, mercury, cadmium, copper, and/or zinc, from drinking water, industrial streams and wastes, in medicine and food industry.Type: GrantFiled: April 30, 2020Date of Patent: February 21, 2023Assignee: Graver Technologies LLCInventors: Anatoly Bortun, James Knoll, Katie Henderson, Joshua Mertz

Patent number: 11364454Abstract: A filter media for implementation in a sugar purification process that allows for a significant increase in sorbent material while maintaining, and enhancing the decolorization and. hydraulic properties. The filter media incorporates sorbent material, fiber having specific properties that allows for small particle sorbent material without jeopardizing the hydraulic properties of the media, and an electrolyte. The sorbent material is an inorganic, an adsorption, or ion exchange media, or a metal-organic framework. The implementation of this filter media in a sugar purification process eliminates the need for a clarification step during refining while providing for enhanced decolorization and hydraulic properties for fluid flow.Type: GrantFiled: May 23, 2019Date of Patent: June 21, 2022Assignee: Graver Technologies LLCInventors: James Knoll, Katie Henderson, Bruce Belcher, Joshua Mertz

Patent number: 11000824Abstract: A filter composition effective in reacting with airborne or gaseous organic impurities, such as formaldehyde. The filter composition is formed from a filter substrate, such as for example, a fibrous web or extruded carbon block, treated with tris-(hydroxymethyl) aminomethane. The unexpected result of this combination is a longer lasting filter capable of adsorbing organic airborne impurities for a much longer period of time than an untreated filter media of the same type. The removal of formaldehyde is presented as an illustrious example.Type: GrantFiled: May 18, 2020Date of Patent: May 11, 2021Assignee: Graver Technologies LLCInventors: Kartik Potukuchi, Robert W.
