20110225883 | VEGETATION WALL - A vegetation wall for supporting vegetation and including at least one panel made from a porous filter media formed of a plurality of strands arranged to form an open, three-dimensional structure with interstitial spaces that provide both air and water permeability. The filter media can filter water, such as by removing nitrogen gas from the water, promoting the colonization of beneficial bacteria that aide in nitrification of the water, and balancing the pH of the water. The vegetation wall can be a free-standing wall, or attached to the side or roof of a building. | 09-22-2011 |
