Wind-aided intensified evaporation (WAIV) is a process exploiting the natural drying power of the wind to evaporate brines than can come from desalination, industry, landfill leachates, and fossil fuel production. Arrays of vertically mounted surfaces that are arranged parallel to the dominant wind direction are kept wetted by recycling the brines over the surfaces allowing loading of 20-40 m2 of wetted surface per square meter of footprint. Unlike spray enhanced evaporation, the liquid-air interface is stabilized by the solid hydrophilic surface so that the wind cannot carry salt spray far downwind of the unit as demonstrated in field tests.
