  • METHOD FOR GENERATING A GRANULAR, GREEN SORBENT MEDIA FOR FILTRATION OF CONTAMINATED WATER BY PROCESSING ALUMINUM-BASED DRINKING WATER TREATMENT RESIDUALS
    Publication number: 20230405546
    Abstract: Filter media for treating contaminated water is produced from aluminum-based water treatment residuals (Al-WTR) commonly produced as a byproduct of water treatment plants. By processing the residuals into small granules, a superior green sorbent product is obtained with the functionality to adsorb contaminants, such as metals and certain nutrients in water. Biopolymers can be incorporated into the filter media to further enhance functionality and hydraulic characters.
    Type: Application
    Filed: May 16, 2023
    Publication date: December 21, 2023
    Applicant: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGY
    Inventors: Dibyendu Sarkar, Viravid Na Nagara, Rupali Datta
