Pro-LPHR Ultra-low Pressure High Salt Rejection RO Membrane Element
PSI MEMBRANE® Pro-LPHR Ultra-low pressure high salt rejection membrane is a third-generation Thin Film Nanocomposite (TFN) RO membrane element.It enhances salt rejection performance while maintaining ultra-low operating pressure, thereby reducing system investment and operating costs.
1.Ultra-low operating pressure combined with high salt rejection rate.
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.
