==What is it?==
==What is it?==
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). Sorbtive Media controls phosphorus by two mechanisms:

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 Rumble Pond Retrofit project in Richmond Hill, Ontario used Sorbtive Media in combination with [[permeable paving|permeable interlocking pavers]] to enhance overall capacity of the pervious pavers.

A partnership between Credit Valley Conservation and the University of Guelph completed a project at the IMAX Corporation headquarters in which Sorbtive Media was used downstream of a [[bioretention]] cell to provide tertiary nutrient treatment.
