  • Titania-based treatment solution and method of promoting precipitation and removal of heavy metals from an aqueous source
    Patent number: 12084366
    Abstract: A treatment solution and method for removing heavy metal contaminants and oxyanion contaminants from an aqueous solution by promoting the affinity of precipitating the contaminants. The method adjusts the pH and the ORP of the contaminated aqueous solution by applying FeCl2 and/or NaOH reducing agents, and using and applying a titania-based treatment solution of TiO(SO4), H2SO4, and FeSO4.
    Type: Grant
    Filed: April 5, 2022
    Date of Patent: September 10, 2024
    Assignee: Marmon Industrial Water LLC
    Inventors: James Knoll, Katie Henderson, Joshua L. Mertz
