Influence of concentrative and dilutive internal concentration polarization on flux behavior in forward osmosis
TLDR
In this paper, the impact of both concentrative and dilutive internal concentration polarization on permeate water flux through a commercially available forward osmosis membrane was investigated and a flux model that accounts for the presence of both internal and external concentration polarization for the two possible membrane orientations involving the feed and draw solutions was presented.About:

Desalination by ammonia–carbon dioxide forward osmosis: Influence of draw and feed solution concentrations on process performance
TL;DR: In this paper, the authors used a commercially available forward direct osmosis (FO) membrane and found that the experimental water fluxes were far lower than those anticipated based on available bulk osmotic pressure difference and membrane pure water permeability data.

Membranes for power generation by pressure-retarded osmosis
TL;DR: In this paper, a model has been developed for obtaining the projected performance of membranes in pressure-retarded osmosis (PRO) from direct and reverse Osmosis measurements, showing that concentration polarization within the porous substrate of the membrane markedly lowers the water flux under PRO conditions.
