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.

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 presiduals and makes it feasible to utilize its pollutant removal potential without requiring any modification to existing best management practices or additional maintenance.
