Abstract
Geotextile composite configured to filter liquids 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.
