Design principles and challenges of bench-scale high-pressure reverse osmosis up to 150 bar

Molecular insights into the structure-property relationships of 3D printed polyamide reverse-osmosis membrane for desalination

“…These property-optimized compositions should then be explained through more a comprehensive structural analysis of the membrane. Finally, with increased interests in high-pressure RO [46][47][48], it is essential to determine the mechanical strength and effects of applied pressure on structural characteristics for various chemical compositions of PA membranes.…”

Recycling Binary Solvent Mixtures Using Distillation and Membrane Separations: Implications for End-of-Life Considerations

“…are operated at pressures between 30 and 69 bar . Several higher-pressure membranes are available that are purportedly designed for pressures of up to 100 bar with current performance closer to 83–95 bar. , In the field of high-pressure reverse osmosis, pressures of up to 100–200 bar have been tested, though membrane compaction, which could impact flux, is not well understood at these pressures. Liu et al .…”

“…28 Several higher-pressure membranes are available that are purportedly designed for pressures of up to 100 bar with current performance closer to 83−95 bar. 28,56 In the field of high-pressure reverse osmosis, pressures of up to 100−200 bar have been tested, though membrane compaction, which could impact flux, is not well understood at these pressures. Liu et al performed their data analysis at 30 bar in order to determine the pure component flux of test solvents in the membrane of interest.…”

Drivers, challenges, and emerging technologies for desalination of high-salinity brines: A critical review

“…3A) [160,161]. A recent study demonstrated bench-scale HPRO operating up to 150 bar (2180 psi) to desalinate feed concentrations as high as 109,000 ppm TDS [162]. A number of manufacturers offer HPRO membranes in the expensive plate-and-frame configuration that can operate under pressures up to 120-203 bar (1740-2940 psi) [163][164][165][166][167] and, more recently, commercial membrane modules in the more widely applied spiralwound configuration capable of handling high pressures up to 120-140 bar (1740-2030 psi) have been reported [168,169].…”
