PX Ultra-High Pressure Membrane Element Series
PSI MEMBRANE® PX Ultra-High Pressure Membrane is a third-generation thin-film nanocomposite (TFN) high-pressure RO membrane element.It provides reliable and efficient technical solutions for industrial users, helping to solve difficult water treatment problems, assist in wastewater reuse and zero-discharge projects to reduce the amount of concentrated water, reduce the amount of salt water in subsequent thermal processes such as evaporation, and optimize the operating cost of zero-discharge systems.
1.Upgraded membrane chemical formula ensures long-term pressure resistance reliability.
2.Professional and efficient national-level expert team provides first-class technical support for customers.
3.Super hydrophilic anti-fouling technology ensures long-term operational reliability.
4.Special membrane sheet and membrane element design can withstand ultra-high feed water pressure of 120 bar.
