Abstract

A composite silt fence configured for capturing pollutants in one embodiment comprises a silt fence fabric including i) a polymeric geotextile fabric particulate filtering layer defining the hydraulic flow capacity for the silt fence, ii) a pollutant capturing layer coupled to the polymeric geotextile fabric particulate filtering layer and configured to capture some select pollutants in water from flow that has passed through the polymeric geotextile fabric particulate filtering layer, and iii) a backing layer coupled to the pollutant capturing layer; and a plurality of stakes secured to the silt fence fabric at spaced locations. The silt fence fabric yields higher hydraulic flow than existing fence constructions with greater sediment retention and pollutant containment features.

Abstract

Geotextile composite configured to filter liquids and related methods are provided. The geotextile composites include a pre-filter layer, a post-filter layer and at least two intermediate filter layers disposed between the pre-filter layer and the post-filter layer. At least one fibrous web that includes composite fibers and adsorptive particulates is disposed between the at least two intermediate filters. The fibrous web has a structural component, and a thermally-bondable, polymeric component. The geotextile can be placed in a location where a liquid that contains contaminants therein resides. The liquids can pass through the geotextile such that the liquid contacts the adsorptive particulate. The contaminants are then filtered from the liquid through contact of the contaminants with the adsorptive particulate.
