Product Description

UltraClean SW series special reverse osmosis membrane element for seawater desalination is a high-end reverse osmosis membrane element. The bottom membrane of the support layer has high compression resistance and thick skin.It is dense and has no defects on the membrane surface; it is resistant to abrasion and chemical degradation; and no post-treatment is required in the manufacturing process of membrane elements. Its wide pH resistance and high cleaning efficiency, can use ordinary acid and alkali for strong and efficient cleaning, because the cleaning is more thorough, the long-term operating pressure of the membrane system is lower, and the service life is higher. It can greatly reduce operating costs and bring long-term optimal economics to seawater desalination systems.


Product  Highlights

1.High salt rejection
