  • METHOD FOR PROCESSING ALUMINUM-BASED DRINKING WATER TREATMENT RESIDUALS TO GENERATE A GREEN-ENGINEERED MULCH FOR REMOVING STORMWATER POLLUTANTS
    Publication number: 20250205684
    Abstract: A green-engineered mulch product and methods for making same are disclosed. The mulch product includes a coating of aluminum-based water treatment residuals which makes the product “green.” Furthermore, coating aluminum-based water treatment residuals on mulch eliminates the problem of the low hydraulic conductivity of aluminum-based water treatment residuals and makes it feasible to utilize its pollutant removal potential without requiring any modification to existing best management practices or additional maintenance.
    Type: Application
    Filed: October 11, 2022
    Publication date: June 26, 2025
    Applicant: The Trustees of the Stevens Institute of Technology
    Inventors: Dibyendu Sarkar, Viravid Na Nagara, Rupali Datta

  • 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.
