A floating cover works by creating a physical barrier on the surface of a liquid, typically water or wastewater. Composed of flexible materials such as geomembranes or reinforced plastics, the cover floats directly on the liquid's surface, which allows it to adapt to changes in water level. This barrier reduces evaporation, controls odors, and inhibits the growth of algae.
The cover's design also helps to maintain water quality by preventing external contaminants from entering the liquid. Essentially, a floating cover is a protective layer that addresses specific challenges associated with open-air liquid storage systems while offering environmental benefits and promoting efficient resource management.
