Active reduction of open-water surface evaporation, typically achieved via floating covers, shade structures, or chemical surfactant monolayers.
Evaporation suppression is the active reduction of water loss from open industrial water bodies through surface intervention. Mechanisms include floating covers (most effective, 90–97% reduction), shade structures (minimal direct effect on evaporation), and chemical surfactant monolayers (short-lived, 20–50% reduction). For industrial water operators in water-stressed regions, evaporation suppression directly reduces operating cost and supports EU Water Framework Directive compliance via reduced abstraction.
The 90–97% reduction figure is the field-verified performance of the AWTT-patented hexagonal floating cover — independently measured by the USDA Bureau of Reclamation. See /heritage for the engineering and validation history.
