Abstract: Water treatment structures may have at least a first geotextile fabric layer; a second geotextile fabric layer; a third geotextile fabric layer; a first filler layer with plastic particles, arranged between the first and second geotextile fabric layers; and a second filler layer with plastic particles, arranged between the second and third geotextile fabric layers, wherein the geotextile fabric layers and the filler layers are within a housing, and wherein the structure is configured such that contaminated water proceeds sequentially through the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer. Methods of treating wastewater may involve passing wastewater, after optional oxygenating and pre-filtering, through such alternating layers of geotextile, preferably nonwoven, and polymer particles.

Abstract: A permeable reactive barrier having two or more layers of a geotextile fabric inoculated with a bioremediation microbe is provided. The permeable reactive barrier further includes two or more layers of coarse-grained geological material separating the two or more layers of geotextile fabric such that any pair of adjacent layers of geotextile fabric is separated by a layer of coarse-grained geological material. The permeable reactive barrier includes a perforated metal casing surrounding and containing the layers of coarse-grained geological materials and geotextile fabric.
