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.
