Seawater Desalination Project in Dalian


The first phase of a seawater desalination plant in Dalian introduces 4 sets of primary systems, including a total of 1260 VONTRON SW series membrane elements, with water production capacity of 160m³/h designed for a single unit. After 72 hours of commissioning, the system achieves a desalination rate of 99.52%, and recovery rate of 44%. The produced water is desalinated by a secondary RO system and ion exchange, finally meeting the standards for boiler water and application water. The seawater resources are utilized rationally to ensure the safety of human water resources and promote the sustainable development of the economy, society, and environment.
