Abstract:
1. A method for cleansing water comprising: attaching an aquatic plant culture to a platform comprising a surface adapted for growing the attached plant culture thereon, the surface comprising a plurality of cells affixed therebeneath, each cell having at least one open end, the porosity and the open end for admitting water to the plant culture and to provide ballast and assist in retaining the platform in the water body during periods of high wind, the platform further comprising a floatable frame from which the platform surface is removable, wherein the frame comprises a pair of beams affixable to the platform surface along opposed sides thereof, the flotation device affixed to the platform surface and adapted to place the platform surface in communication with water in a body of water, the flotation device floatable atop the water body, water reaching the giant culture cleanable thereby; floating the platform in the water body, the platform surface adjacent a surface of the water body, at least a portion of the platform surface being porous; permitting water from the water body to contact the plant culture through the porous platform surface, the plant culture adapted for removing undesired matter from the water; and harvesting plant biomass from the plant culture by removing the platform surface from the water body, and harvesting the biomass at a location apart from the water body while leaving the floatable frame of the platform in place in the water body.
