Seawater Desalination RO Element

This series of elements have the characteristics of low operating pressure, low equipment investment, good desalination performance and stability.Seawater Desalination has relatively strict requirements for RO Element, mainly in terms of salt rejection and corrosion resistance. The salt content of seawater treated by Seawater Desalination RO Element can be greatly reduced.

SKU: N/A Category:

Seawater Desalination RO Element 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, waste water reuse,concentration and recovery of high value-added substances such as food and pharmaceuticals,etc.
