Desalination Abnormal weather and lack of water resources have become an important issue in the future. For systems that have been treated with water, the desalination system has excellent capabilities for high-concentration and poor water quality. Seawater desalination is aimed at water quality below 32,800ppm to 35,000ppm, and inorganic salts and organic salts can still be removed as high as 99%. Therefore, the seawater desalination system can be used as a multi-purpose application, such as: salt water desalination, mobile emergency rescue water, wastewater treatment and recycling water... etc. In the future, desalination may be one of the necessary options for water treatment systems.
