Pro-SW High Flux Seawater Desalination RO Membrane Element
PSI MEMBRANE® Pro-SW membrane is a third-generation thin-film nanocomposite (TFN) high-pressure high salt rejection RO membrane element. Unique anti-fouling membrane technology endows it with excellent anti-fouling ability and cleanability,ensuring high salt rejection performance while reducing energy consumption and extending cleaning cycles.
1.Wide flow channel reduces membrane fouling probability and improves cleaning efficiency.
2.Stable chemical resistance to cleaning ensures long-term operational reliability.
3.Excellent anti-fouling performance of TFN surface for long service life.
4.TFN membrane flux is generally 30% higher than traditional TFC, with lower energy consumption.
