SEA WATER DESALINATION RO MEMBRANE ELEMENTS

NURPEX NPSW8040-400 and NPSW8040-440 are spiral-wound reverse osmosis membrane elements developed for sea water desalination and high-salinity water treatment. They are engineered to deliver high salt rejection and stable permeate flow in demanding desalination systems.

The optimized membrane element structure supports efficient water production, stable operating performance, and practical system design. These elements are suitable for drinking water production from seawater, industrial water reuse, near-zero discharge systems, and concentration of high-salinity streams.
