Patent number: 11958764Abstract: Processes are provided for the kinetically efficient reduction of selenate species to selenide species using chromous ions in acidic solution. This reduction may advantageously be carried out in the presence of sulphate species, with selective selenate reduction in preference to the reduction of sulfate. The reduced selenate may be removed from the chromous-treated solution, for example by precipitation of a copper-selenide solid. The chromic ions formed by reaction of chromous ions in the reduction of selenate may also be removed from solution, for example by addition of a base to form an insoluble chromic hydroxide solid. The chromic hydroxide may be recycled to regenerate chromous ions, for example by electrolysis. In this way, systems are provided for continuously removing dissolved selenium from wastewater streams.Type: GrantFiled: May 23, 2022Date of Patent: April 16, 2024Assignee: Seabridge Gold Inc.Inventors: Maryam Mohammadi, Berend Wassink, Jianming Lu, David Dreisinger

Patent number: 11896948Abstract: A synergistic composition can be used to treat water containing nitrogen compounds and phosphorus compounds. The synergistic composition includes iron filings, clay particles, aluminum particles, and sand particles. The iron filings, clay particles, and aluminum particles act synergistically to remove nitrogen compounds and phosphorus compounds from water. Specifically, the clay particles attract the nitrogen compounds and the phosphorus compounds to be absorbed onto a surface of the iron filings and the clay particles. The aluminum particles react with the nitrogen compounds via an oxidation reaction to form ammonia compounds, and react with the phosphorus compounds to produce aluminum phosphate. As such, the synergistic relationship between the iron filings, clay particles, and aluminum particles remove nitrogen and phosphorus compounds from water and recover the compounds in usable forms, namely, ammonia and aluminum phosphate.Type: GrantFiled: January 26, 2023Date of Patent: February 13, 2024Assignee: University of Central Florida Research Foundation, Inc.Inventors: Ni-Bin Chang, Debra Reinhart, A H M Anwar Sadmani
