Abstract
    High-pressure reverse osmosis (HPRO) has been recently proposed for the energy-efficient desalination of hypersaline brines. To advance this technology, substantial innovation is needed, including the capacity to test membranes at ultra-high hydraulic pressures. Here, we report on the development of an apparatus designed and constructed specifically for coupon-scale membrane research in HPRO. The capabilities of the closed-loop crossflow system were demonstrated through desalination experiments at hydraulic pressures up to 150 bar and feed concentrations up to 2.0 M (117 g L−1) NaCl. Several safety-related design considerations are highlighted in addition to the design of a custom-built membrane test cell and high-pressure seal to ensure leak-free, safe operation. Corrosion control protocols were also developed to enable long-term system compatibility with corrosive hypersaline feed solutions. Lastly, we highlight novel experiments that are now possible with this apparatus and discuss the benefit it represents to HPRO development by the membrane community.
