==Enhanced Phosphorous Removal==

Particulate phosphorus is removed to a good extent in LIDs due to the sedimentation and filtration mechanisms offered by these features. To further improve the removal of total phosphorus, the removal of dissolved phosphorus is targeted. As explained in the previous section, adsorption is the main removal mechanism for dissolved phosphorus and aluminum and iron are the main sorptive elements.  Therefore, including [[Additives| additives]] in filter media blends can enhance phosphorus retention.  Examples of such additives are [[Iron filings (ZVI)|iron filings]] or zero valent iron, iron-enriched or [[red sand|“red” sand]], and [[water treatment residuals]]. Other types of additives that can also provide sorption capacity are [[biochar]], [[Bold & Gold]], [[Smart Sponge]], and [[sorbtive media]].
