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.

Production of Electric Power by mixing Fresh and Salt Water in the Hydroelectric Pile
TL;DR: In this article, it was shown that when a volume V of a pure solvent mixes irreversibly with a much larger volume of a solution the osmotic pressure of which is P, the free energy lost is equal to PV.

Power generation with pressure retarded osmosis: An experimental and theoretical investigation
TL;DR: 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).

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.
