UHP RO
The UHP RO membrane is NanoH2O’s ultra-high pressure reverse osmosis membrane, specifically designed for treating water sources with very high salinity and TDS levels. The membrane operates at pressures up to 120 bar (1,740 psi) and delivers 99.85% stabilized salt rejection, a permeate flow rate of 8,500 GPD (32.2 m3/d), and an active membrane area of 380 ft2 (35 m2). These features help maximize water recovery, reduce wastewater volume, and optimize operating costs in ZLD/MLD systems.
