Current practice of using thermally driven methods to treat hypersaline brines is highly energy-intensive and costly. While conventional reverse osmosis (RO) is the most efficient desalination technique, it is confined to purifying seawater and lower salinity sources. Hydraulic pressure restrictions and elevated energy demand render RO unsuitable for high-salinity streams. Here, we propose an innovative cascading osmotically mediated reverse osmosis (COMRO) technology to overcome the… 
Comparison of Energy Consumption of Osmotically Assisted Reverse Osmosis and Low-Salt-Rejection Reverse Osmosis for Brine Management.
TLDR
This work utilizes process modeling to systematically compare the energy consumption of OARO and LSRRO for MLD/ZLD applications and concludes with a discussion on the practicability of O ARO andLSRRO based on membrane module availability and capital cost, suggesting that L SRRO could potentially be more feasible than OARo.

Selectivity and Mass Transfer Limitations in Pressure-Retarded Osmosis at High Concentrations and Increased Operating Pressures.
TLDR
A new method is used to characterize membranes under a variety of pressures and concentrations, finding membrane selectivity decreases as the draw solution concentration is increased and pumping energy requirements increase, highlighting important new challenges for development of systems utilizing hypersaline draw solutions.
Performance limiting effects in power generation from salinity gradients by pressure retarded osmosis.
TLDR
