Textile Filter

Composed of geosynthetic fabrics or geotextiles, textile filters provide surface area within the media itself and void volume between the pieces of media. The increased surface area within the media creates more places for biological growth to occur, and therefore more area for treatment to occur.

Textile filters have two common configurations: (1) randomly-sized textile coupons arranged in three separate horizontal lifts and (2) vertically hanging sheets of fabric. The textile material is contained in a prefabricated container.
