SW11-2540

SW series of sea water aromatic polyamide RO element developed by VONTRON for seawater desalination. This series of elements have the characteristics of low operating pressure, low equipment investment, good desalination performance and stability.
 
SW series membrane elements are generally suitable for the treatment of seawater and brackish water with high concentration. It can be used for seawater desalination, desalination of brackish water with high concentration, boiler replenishment water in power plants, wastewater reuse, concentration and recovery of high value-added substances such as food and pharmaceuticals, etc.
