Filtrexx® Vegetated Filter Strip is a temporary or permanent filtration practice used to reduce site sediment and soluble pollutants, such as nutrients, heavy metals, bacteria, and petroleum hydrocarbons, from leaving a site and entering conveyance systems or receiving waters. Permanent vegetation is designed to increase storm water infiltration and pollutant filtration. Filtrexx® Vegetated Filter Strips are of a specified width and utilize a 1 to 2 inch (25-50mm) layer (135 to 270 cubic yards/acre) of Filtrexx® Growing Media™ blended with a specified seed mix. The GrowingMedia is applied with a pneumatic blower or similar equipment.
