Influence of metal mesh wettability on fog harvesting in industrial cooling towers

Fresh water stress can be alleviated by harvesting water from the fog plumes of industrial cooling towers (CT) using metal meshes. A typical CT fog harvester contains inclined meshes that intercept the rising fog plume. Water droplets deposit on these meshes and then roll down the surfaces due to gravity into a collection manifold below the mesh. The amount of water collected depends on the fraction of fog that is intercepted by the meshes and …
