Russian Chemical Reviews, 1988
After a brief presentation of the principal kinetic and thermodynamic aspects of the theory of reverse osmosis, the present review examines various physicochemical mechanisms of the selectivity of membranes with respect to electrolyte solutions: the electrochemical mechanism, related to the charge of the pore surface; the dielectric exclusion of ions ...

In the last few decades, desalination processes have played a crucial role in meeting the growing demand for water. Desalination process consists of raw water, desalination device, product water and energy. Among the desalination processes, membrane-based reverse osmosis desalination has become popular because of its characteristics such as ambient ...

AbstractThe nonlinear problem of reverse osmosis in annular conduits is solved by a series expansion method which is very accurate in the diffusion entrance region near the inlet of the membrane section. It is found that polarization at the outer membrane surface is significantly greater than at the inner wall.In the diffusion entrance region, for the ...

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1986
Two variational principles control isotonic osmosis and reverse osmosis: the principle of least dissipation of energy referring to a definite time integral and the principle of least constraint referring to the stationary (extremum) value of a volume integral.An extended form of the Nernst–Planck equation resulting from the time variation has been ...
