We used media just like that in a "bio-tower" to treat fuel-contaminated groundwater. Bacteria will easily grow on that stuff.
On a much larger scale, we're working on retrofitting an existing wastewater treatment plant that uses RBC units (rotating biological contactors). Very similar to the biowheels used for certain aquarium filtration systems.
