Abstract
Now, the lack of pure water is a serious problem in the world. One of the solutions is the desalination of seawater, and there are several ways, for example evaporation, membrane and freezing methods, but every method has the problem in construction and operating costs. This paper described a new desalination method and device by the liquid column of seawater and decompressed evaporation. At this time, the seawater at the top of the vessel set vertically is decompressed by the liquid column to the vacuum, and is boiled and evaporated. It is condensed by cooling and then the pure water is generated.
