Abstract (en)

[origin: WO9932408A1] An apparatus is disclosed utilizing permeable treatment media (3) for treatment of contamined water, along with a method for enhanced passive flow of contamined water through the treatment media. The apparatus includes a treatment cell (1) including a permeable structure that encloses the treatment media, the treatment cell may be located inside a water collection well (13), exterior to a water collection well, or placed in situ within the pathway of contaminated groundwater. The apparatus and process for passive flow and groundwater treatment utilizes a permeable treatment media made up of granular metal, bimetallics, granular cast iron, activated carbon, cation exchange resins, and/or additional treatment materials. An enclosing container (2) may have an outer permeable wall (5) for passive flow of water into the container and through the enclosed treatment media to an effluent point.
