  • Contaminant removal from water using polyelectrolyte coated fly ash
    Patent number: 10843940
    Abstract: A polyelectrolyte coated fly ash is described with a method of making and a method of using for the adsorption of a contaminant from a solution. The polyelectrolyte coated fly ash may be made by treating the oil fly ash with acid, and then contacting the product with a positive polyelectrolyte to create a first polyelectrolyte layer, and then with a negative polyelectrolyte to create a negative polyelectrolyte layer. The resulting polyelectrolyte coated fly ash quickly adsorbs contaminants from solution, and may be cleaned and reused.
    Type: Grant
    Filed: June 28, 2018
    Date of Patent: November 24, 2020
    Assignee: King Fahd University of Petroleum and Minerals
    Inventors: Tahar Laoui, Fatai Abidemi Olabemiwo, Bassam Tawabini, Mazen Khaled

  • Continuous flow decontamination of an MTBE-contaminated aqueous liquid
    Patent number: 10167212
    Abstract: A process for decontaminating a contaminated aqueous liquid comprising methyl-tert-butyl ether (MTBE) involving pretreating the contaminated aqueous liquid with chlorine and/or a hypochlorous acid salt and irradiating the aqueous liquid with an ultraviolet wavelength to produce a radical molecular species that degrades the MTBE. MTBE is degraded into at least one degradation byproduct including tert-butyl formate (TBF), tert-butyl alcohol (TBA), acetone, carbon dioxide, and water.
