Desalination by Osmosis-Reverse Osmosis Couple
Science, 1968Water is separated from brines by a semipermeable membrane. Water flows by osmosis across the membrane into a sealed chamber where it creates pressure. This pressure is transmitted by a water-immiscible liquid piston to a second chamber where it effects reverse osmosis. Water-removal rates are calculated.

Abstract It is demonstrated that in the absence of buoyancy driven convection, as in microgravity, the osmotic process is modified considerably.

Forum on osmosis. IV. More on osmosis and diffusion
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1979A brief summary is presented of the Gibbsian view of chemical drives and of its mechanical interpretation, including a description of the “diffusion force” that arises from an interplay between fluctuations and dissipation. Osmotic flows are shown to be driven by diffusion forces acting at the membrane interface, and not by the effects of Hammel and ...

Quarterly Reviews of Biophysics, 1979
It has virtually become a truism that osmosis, and the inseparable array of related processes comprising ultrafiltration, diffusion, anomalous osmosis, etc., has found its final and lasting exposition to which anything can only be added by way of a few finishing touches. This view, as I shall attempt to show, is quite wrong, if for no other reason than

The reverse osmosis process is discussed with particular reference to systems involving aqueous solutions and Loeb-Sourirajan-type porous cellulose acetate membranes. Mechanisms of the process and porous cellulose acetate membrane technology are briefly reviewed.

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 ...

Day Care & Early Education, 1983 The typical nursery school in the province of Quebec, Canada, is conducted in French, the official language of schools and business. Even so, it is not unusual to find English- as well as French-speaking students at many of these schools. Both languages are spoken in the province.
