| Sorbtive media is an oxide-based, high surface area reactive engineered media that absorbs and retains large amounts of dissolved [[phosphorus]]. It does not desorb (leach) pollutants and has a low total phosphorus effluent concentration (< 0.1 mg/L).

− | The “Sorbtive Media” website highlights multiple projects where their product was used for phosphorus removal. At the Sturgeon Meadows Stormwater Management Facility in Leamington, Ontario, Sorbtive Media was applied as a retrofit component to enhance pollutant removal withing an existing [[dry pond]] as part of a [[treatment train]]. A 30 cm layer was applied within retrofitted trenches in combination with washed stone and rip rap rock to manage the expected treatment flow. | + | The “Sorbtive Media” website highlights multiple projects where their product was used for phosphorus removal.
