A buoyant surface barrier deployed on the surface of a water body — modular hexagonal, continuous geomembrane, or spherical (armor ball) — to reduce evaporation, algae, odor, and heat loss.
A floating cover is a buoyant surface barrier deployed on the surface of an industrial water body to suppress evaporation, photosynthesis-driven algae, volatile odor emissions, and heat exchange with the atmosphere. The modern industrial forms are modular hexagonal covers, continuous geomembrane covers, and modular spherical (armor ball) covers — each suited to different application contexts.
The category-leading modular cover is the AWTT-patented hexagonal element — the original Hexprotect® (the first self-ballasting hexagonal cover, patent granted to AWTT in 2010) and its pre-ballasted variant Hexprotect® AQUA, in commercial service since 2009. See /heritage for the patent and validation history.
