Foam Products - Polyethylene Foam

Algae growth can be found in wastewater lagoons, cooling ponds, aquaculture facilities, ponds and other natural bodies of water. Surface water treatment plants utilize open air presedimentation basins (or raw water reservoirs) these suffer from algae growth during warm weather periods, typically March through November. Typically a variety of strategies and combinations of strategies are implemented to control or reduce algae concentrations including: chemical algicides, aeration, and chemical addition for nutrient (phosphorous) removal. 3RFoam offers a unique, cost effective final resolution of this problem.

The only option available for truly “eliminating” algae would be significantly altering the environment in which algae can grow and thrive. Biomanipulation, algicides, and food removal all only offer marginal success, the one remaining environmental element available for alteration is sunlight (UV). 3RFoam offers UV filtering cover made from continuous strips of a composite media (flotation media covered by a geotextile) approximately 4-5 ft. in width, sewn together, and held in place by burying the outer edges in the perimeter dikes – similar to a lagoon or landfill liner. These permeable floating covers are made by using 3RFoam. The cover, resting on the surface of the water, allows rainwater to pass through it. Winds will not lift the cover off the surface of the water, which allows for a simple anchor system at the perimeter.

The 3RFoamFloating Cover system offers easy deployment, uses proven materials, and is highly cost effective in the treatment of algae growth.
