Power generation with pressure retarded osmosis: An experimental and theoretical investigation
TLDR
In this paper, a pressure retarded osmosis (PRO) model was developed to predict water flux and power density under specific experimental conditions, relying on experimental determination of the membrane water permeability coefficient (A), the membrane salt permeability coefficients (B), and the solute resistivity (K).About:

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.
