Influence of concentrative and dilutive internal concentration polarization on flux behavior in forward osmosis
TL;DR: 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.

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.

Coupled effects of internal concentration polarization and fouling on flux behavior of forward osmosis membranes during humic acid filtration
TL;DR: In this article, the effects of ICP and fouling on forward osmosis (FO) flux behavior were systematically investigated and both theoretical model and experimental results demonstrated that the FO flux was highly nonlinear with respect to the apparent driving force (the concentration difference between the draw solution and the feed water).
