Changes

A number of granular amendments have been demonstrated to improve nutrient removal from discharge water in BMPs such as [[bioretention]] systems, [[stormwater planters]], [[absorbent landscapes]], [[sand filters]] or [[green roofs]].  

Design innovations to improve water quality treatment performance of filter media mixtures involve the incorporation of additives to enhance retention of reactive or dissolved pollutants.  A number of granular amendments have been demonstrated to improve nutrient removal from discharge water in BMPs such as [[bioretention]] systems, [[stormwater planters]], [[absorbent landscapes]], [[sand filters]] or [[green roofs]].  

There are two primary processes involved, chemical 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.
