Low temperature multi-effect distillation process

Low-temperature multi-effect seawater desalination refers to the distillation desalination technology with the highest evaporation temperature of brine below 70℃, which is one of the most energy-saving methods in distillation. Its principle is to connect a series of horizontal tube falling film evaporators in series, and obtain distilled water that is several times the amount of steam through multiple evaporations and condensations. Low-temperature multi-effect distillation technology has the advantages of energy saving, low seawater pretreatment requirements, and high desalinated water quality.
