Abstract: A floway system for a building roof includes a substrate for supporting a periphyton culture that removes nutrient pollution from surface water and isolates the building envelope from solar-induced heat. The substrate is seedable to form a floway. a harvester for harvesting periphyton from the substrate. Water desired to be bioremediated is channeled to an inlet of the periphyton culture. A gutter system includes a sector for collecting cleansed water from an outlet of the periphyton culture having a drain for permitting water to be emptied therefrom and a sector for collecting periphyton harvested from the substrate therein. An element is provided for directing material exiting the periphyton culture outlet selectively between the water-collecting sector and the periphyton-collecting sector.

Abstract: A system and method for remediating a body of water and collecting suspended and dissolved solids therefrom are provided. The system includes a water-impervious lining positionable in a depression in or adjacent a body of water. The lining and depression define a treatment vessel, which includes a treatment portion, an outlet portion for containing treated water, and an outflow weir between the treatment portion and the outlet portion. Water to be treated is transported from the water body to the treatment portion. An entrapment element is delivered and mixed into the transported water, the entrapment element for capturing suspended and dissolved solids in the transported water and effecting a separation between the captured solids and water cleansed therefrom. The captured solids can be removed from the treatment basin, and the cleansed water can move through a channel in the outflow weir into the outlet portion.

Abstract: A floating plant culture system has improved strength and durability and includes a substantially planar platform having a length along opposed sides thereof and a width along front and back thereof generally perpendicular to the sides. The platform is adapted for growing a culture of attached plants including micro- and macrophytes thereon. Beneath the platform are affixed a plurality of cells extending in bridging relation to the sides and open at each end adjacent the sides. The cells are placeable in fluid communication with a body of water desired to be remediated. Affixed along at least a portion of the sides extend a pair of opposed hollow beams, for providing flotation to the platform. The beams are also placeable in fluid communication with the body of water, and an upper surface of the platform is floodable by the body of water from beneath for submerging plants attached thereto.

Abstract: A floway system for a building roof includes a substrate for supporting a periphyton culture that removes nutrient pollution from surface water and isolates the building envelope from solar-induced heat. The substrate is seedable to form a floway. A basin is provided for holding water to be treated, and a pump for pumping water therefrom to the floway inlet. At the floway outlet is positioned an effluent-collection gutter, which channels effluent to a collection vessel. Algal biomass can be harvested. A flexible divider is positioned in the gutter along the long axis, a top edge of securable adjacent the floway outlet so that, during harvesting, algal biomass is scraped into a distal section of the gutter, and thence to a biomass collection basin. The harvester can include a scraper and mechanism for traveling down the floway. The harvester can also move between adjacent floways and to the building roof.
