Polyethylene floating cover

for reservoirUV protection

Barrier Ball® is a floating cover for liquid bodies composed of plastic spheres loaded with water (ballast). As a whole, the spheres cover 91% of the surface and form a barrier that reduces the liquid-gas interface, the entry of sunlight and eliminates the water mirror, obtaining the following benefits: Evaporation reduction between 80% and 85%. Energy consumption reduction up to 75%. Significant reduction of algae growth. Significant reduction of odors, gases and corrosive vapors. Effective deterrence of fauna to avoid contact with the liquid. Barrier Ball® spheres are made of 100% recycled High Density Polyethylene (HDPE) to which stabilizing additives are added to prevent the effects of UV radiation on the material. This gives them a lifespan of at least 20 years and once their life cycle is completed they are removed and recycled. In addition, we use 100% non-conventional renewable energy in the manufacturing process. Barrier Ball® floating cover provides a simple, reliable, environmentally friendly, highly efficient and long-term solution to the problems of evaporation, heat loss, odors, toxic and/or flammable vapors, the presence of algae and the protection of the fauna. Modeling using advanced calculation tools such as CFD ANSYS Fluent and TRNSYS has enabled characterizing and optimizing the Barrier Ball® spheres to maximize their efficiency, know their behavior in different weather conditions and perform savings simulations according to the geographical location of the surface to be covered. These works were validated by the Engineering Department of the Faculty of Physical and Mathematical Sciences of the University of Chile.
