Fog Collection Materials: A material’s wind flow porosity and surface area available for fog droplet condensation are both important factors in determining collection rates [Shemenauer, Joe, 1989″ Fog tunnel and on-site testss showed that Enkamat® 7010 thin (double layer) and Enkamat® 7220 flatback (single layer) perform better than 35% raschel mesh – increasing fog collection yields by as much as 200%. Other Enkamat® advantages include:1) worldwide availability with established distribution in Lima, 2) cost effectiveness, 3) UV and weather resistance, 4) availability with an integral reinforcing web for added strength, 5) inert and not harmful to the environment, 6) approved for use in applications involving potable water, 7) manufactured using more than 40% post-consumer recycled content []
