SINOMEMB® Sea Water SNSW Series RO membrane elements
Industrial Sw RO Membrane for Water Treatment Purifier
The SW (Sea Water) series is an aromatic polyamide composite membrane element suitable for seawater desalination. This series of products improves the desalination rate and water production by optimizing the diaphragm performance and membrane element structure, and has the characteristics of low operating pressure, good desalination effect, less equipment investment and stable system operation. SW series membrane modules are suitable for the treatment of seawater, high concentration brackish water and materials, can be used in seawater desalination, reclaimed water reuse, zero discharge and garbage permeate and other fields, and can also be used for the concentration and separation of high value-added substances such as food and medicine
