Hydranautics PRO-XP1 Ultra High-Pressure Reverse Osmosis Membranes
PRO-XP membranes are designed for ultra high-pressure reverse osmosis applications, capable of treating high total dissolved solids (TDS) feed water and concentrating it up to 120,000 ppm (12%). Engineered to operate at pressures up to 1,800 psi (12.4 MPa), these membranes serve as a critical pre-treatment step in Zero Liquid Discharge (ZLD) systems, significantly reducing the capital and operating expenditures associated with downstream thermal processes such as evaporators and crystallizers.
