Patent number: 11524901Abstract: This invention provides a method for efficiently separating magnesium and lithium from salt lake brine, and simultaneously preparing high-purity magnesium oxide and battery-grade lithium carbonate. The detailed processing steps are as follows: (1) adding urea into the brine to dissolve, (2) placing the solution into the reactor for hydrothermal reaction, the magnesium ion will precipitate and enter the solid phase; (3) filtering and drying the production to get the magnesium carbonate solid, while the lithium ion remains in the liquid phase; (4) after directly concentration and precipitation, the battery-grade lithium carbonate can be obtained, while the calcination of solid-phase product results in the high-purity magnesium oxide. In this method, urea is used as the precipitant to separate magnesium and lithium in salt lake without introducing any new metal ion, and the brine solution is not diluted. The solid product is white and fluffy powder, which is easy to filter and separate.Type: GrantFiled: March 8, 2019Date of Patent: December 13, 2022Assignee: BEIJING UNIVERSITY OF CHEMICAL TECHNOLOGYInventors: Xu Xiang, Xue Duan

Patent number: 11498884Abstract: A system for recovering fat, oil and grease (FOG) from wastewater has multiple annular flotation zones in a concentric configuration surrounding a central column to create progressively increasing surface areas for FOG and solid particles flotation. Each flotation zone may be equipped with an independent pressurized micro air and/or ozone bubbles distribution system. The FOG is recovered in the first flotation zone without chemical additions. Coagulant and flocculant may be added in the second flotation zone to maximize removals of biochemical oxygen demand (BOD), total suspended solids (TSS), and colloidal particulates and produce clear effluent. Magnesium chloride is added in the third flotation zone to remove phosphorus and to form struvite particulates that can be used as fertilizer. Since both organic loading and solid loading in the treated effluent are significantly reduced, poultry processing plants can more easily meet wastewater treatment plant discharge limits and avoid surcharges.Type: GrantFiled: August 17, 2018Date of Patent: November 15, 2022Assignee: Besser Tech Holdings LLCInventors: William Michael Fields, Yuanchun Xu, Guichun Zhang

Patent number: 11447401Abstract: Separation columns and methods for PFAS removal from water resources. Each column comprises perforated trays, level-controlled gates and air spargers placed on the top of each tray. Air bubbles of optimum size injected on the surface of each tray rise to the top of each tray, separating PFAS, thus creating a PFAS-enriched foam at the top. The amount of air or other gas injected at each stage of the column is optimally determined to increase the gas-water contact time and decrease enriched foam production. The foam is collected from the surface and undergoes a simple low-pressure evaporation process to break the bubbles. Multi-stage air injection using a sparger or distributer to inject air or other gas bubbles in each tray produces higher turbulence on each tray and more fresh and small bubbles of controlled size along the column height, thus enhancing contaminant removal and reducing operating costs.Type: GrantFiled: May 6, 2020Date of Patent: September 20, 2022Assignee: Arrowhead Center, Inc.Inventors: Zahra Abbasian Chaleshtari, Reza Foudazi

Patent number: 11440828Abstract: The present invention relates to a method of treating sludge containing phosphorus, ammonia and magnesium and enhancing the dewaterability of the sludge. The sludge is directed into a biological fermenter operated under anaerobic conditions. By controlling the temperature of the sludge in the fermenter or the hydraulic retention time of the sludge in the fermenter, phosphorus, ammonia and magnesium is released from the solids in the sludge into a liquid forming a part of the sludge. Sludge from the fermenter is subjected to a solids-liquid separation process that produces a concentrated sludge and a liquid. The concentrated sludge or separated solids is directed to a thermal hydrolysis reactor that thermally hydrolyzes the concentrated sludge. After thermally hydrolyzing the concentrated sludge, the concentrated sludge is directed to an anaerobic digester that anaerobically digests the concentrated sludge.Type: GrantFiled: December 18, 2018Date of Patent: September 13, 2022Assignee: Veolia Water Solutions & Technologies SupportInventors: Hong W.
