SW Series is an aromatic polyamide composite membrane element for seawater desalination. By optimizing the structure of membrane element, this series of membrane elements can increase water production. Under the same water production requirement, the number of membrane elements can be reduced. It has the characteristics of low operating pressure, low equipment investment, good desalination performance and stability. In particular, its high desalination rate ensures that drinking water can be obtained from seawater through first-order reverse osmosis.
SW series membrane elements are suitable for the treatment of seawater and brackish water with high concentration. They can be used for the treatment of seawater desalination, desalination of brackish water with high concentration, boiler feed water in power plants, wastewater reuse, concentration and recovery of high value-added substances such as food and medicine, etc.
