A number of granular amendments have been demonstrated to improve nutrient removal from discharge water in BMPs such as bioretention cells, absorbent landscapes, sand filters or green roofs. There are two primary processes involved, precipitation and adsorption. Both mechanisms are ultimately finite, but have been shown in come cases to make significant improvements on the discharged water quality over several years.
