Pro-BW Brackish Water RO Membrane Element
PSI MEMBRANE® Pro-BW brackish water membrane s a third-generation thin-film nanocomposite (TFN) 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.Stable chemical resistance to cleaning ensures long-term operational reliability.
2.Excellent anti-fouling performance of TFN surface for long service life.
3.TFN membrane flux is generally 30% higher than traditional TFC, with lower energy consumption.
