Publication number: 20230405526Abstract: A system and method for producing minerals from divalent ion-containing brine stream includes rejecting sulfate from a divalent-ion rich reject stream in a first nanofiltration seawater reverse osmosis (NF-SWRO) unit, producing solid calcium sulfate dihydrate and a magnesium-rich brine stream in a first concentration unit, concentrating the magnesium-rich brine stream to a saturation point of sodium chloride in a second concentration unit, producing solid sodium chloride and a supernatant product stream in a first crystallizing unit, produce a concentrated magnesium-rich bittern stream from the supernatant product stream in a third concentration unit, and at least one of producing hydrated magnesium chloride from the concentrated magnesium-rich bittern stream in a second crystallizing unit and producing anhydrous magnesium chloride by prilling the concentrated magnesium-rich bitterns stream under a hydrogen chloride atmosphere in a dry air process unit.Type: ApplicationFiled: August 30, 2023Publication date: December 21, 2023Inventors: Ahmed Saleh Mohammed ALAMOUDI, Mohammed Farooque AYUMANTAKATH, Nikolay VOUTCHKOV, Seungwon IHM, Christopher Michael FELLOWS, Eslam ALWAZNANI

Publication number: 20230399244Abstract: A system and method for producing from saline source water a product containing an increased ratio of multi-valent ions to mono-valent ions, which includes multiple nanofiltration units arranged to selectively remove mono-valent ions from the water fed into each nanofiltration stage in the nanofiltration permeate stream while retaining multi-valent ions in the nanofiltration reject stream. The rate at which the increase in the multi-valent ion to mono-valent ion ratio is obtained may be enhanced by introduction of lower salinity water into the nanofiltration reject between stages, and by recirculating a portion of downstream nanofiltration reject flow into an upstream nanofiltration unit. The enhanced multi-valent ion product is suitable for multiple uses, including irrigation of plants and remineralization of desalinated water.Type: ApplicationFiled: August 29, 2023Publication date: December 14, 2023Applicant: Saline Water Conversion CorporationInventors: Ahmed Saleh Mohammed ALAMOUDI, Christopher Michael FELLOWS, Mohammed Farooque AYUMANTAKATH, Nikolay VOUTCHKOV, Sangho LEE, Seungwon IHM

System and Method for Monovalent Ion Purification Using Multi-Pass Nanofiltration With Recirculation
Publication number: 20230191330Abstract: A system and method for increasing the efficiency of a multi-pass nanofiltration system associated with water desalination and mineral extraction. A saline source water is preferably subjected to a first treatment by passage through a first nanofiltration unit, followed by a second treatment by passage through a second nanofiltration unit. At least a portion of the second nanofiltration unit's reject stream is recirculated to the inlet of the first nanofiltration unit, thereby increasing the production of permeate from the first nanofiltration unit, as well as increasing the purity of monovalent ions in the first nanofiltration unit permeate. Further nanofiltration units with one or more recirculated reject streams may be connected in series and/or in parallel with the first and second nanofiltration units.Type: ApplicationFiled: December 17, 2021Publication date: June 22, 2023Inventors: Ahmed Saleh Mohammed ALAMOUDI, Mohammed Farooque AYUMANTAKATH, Nikolay VOUTCHKOV, Seungwon IHM -

Patent number: 10947143Abstract: A system and method for producing very high concentration brine streams from which commercially efficiently obtained minerals may be obtained is produced by a dual membrane brine concentrator system (DTRI Concentrator). The system includes a nano-filtration system which removes divalent ions from the seawater, a brine concentrator such as a hollow fine fiber forward osmosis system which receives and further concentrates the brine rejected from the nano-filtration system, a SWRO system which receives the NF system permeate and removes monovalent ions, and another brine concentrator which further concentrates the brine rejected from SWRO system. Various permeate and reject brine flow may be forwarded through the Dual Membrane Brine Concentrator system, and multiple stages of the system components may be used, to enhance brine concentration and improve system efficiency.Type: GrantFiled: April 1, 2019Date of Patent: March 16, 2021Assignee: Saline Water Conversion CorporationInventors: Ahmed Saleh Mohammed Alamoudi, Mohammed Farooque Ayumantakath, Nikolay Voutchkov, Seungwon Ihm

Publication number: 20210039044Abstract: A system and method are provided for sequestering of greenhouse gas in conjunction with operation of a desalination facility or water or wastewater treatment plant from which water hardness and alkalinity has to be adjusted to meet water quality requirements. Carbon dioxide in solution with a source water stream, such as a high-divalent ion desalination unit discharge stream or a low calcium concentration permeate stream, chemically reacts with a calcium-based compound such that calcium bicarbonate by mixing with a solution containing the calcium-based compound or by direct contact with a solid form of the compound. Preferably the pH of the calcium bicarbonate-containing output stream is adjusted to maintain pH in a range providing a nearly 100% sequestered carbon dioxide soluble product. The soluble product may be discharged to a natural water body or used as drinking, irrigation or industrial process water, or in another process having a pH of 7.5-9.0.Type: ApplicationFiled: August 9, 2019Publication date: February 11, 2021Inventors: Ahmed Saleh Mohammed ALAMOUDI, Mohammed Farooque AYUMANTAKATH, Nikolay VOUTCHKOV, Seungwon IHM
