• Resumen

  • The article discusses the process of seawater collection through boreholes for the operation of desalination plants. Seawater collection is essential for desalination, and it must have a specific electrical conductivity of around 50,000 µΩ/cm, with an appropriate temperature of 25 ºC. The article describes the characteristics of the borehole, such as the diameter, suction surface, and casing, as well as the depth at which the seawater is collected. The drilling techniques for boreholes are also mentioned, which include percussion and rotopercussion machinery. Finally, the article explains the Ghyben-Herzberg formula for determining the hydrostatic equilibrium between freshwater and saltwater, which is used to determine the depth of the interface with respect to sea level.
