We report computer simulations of semi-permeable membranes used to study electrolyte solutions undergoing osmosis, reverse osmosis, and electro-osmosis. The semipermeable roembrane, which is atomistic in nature, has been modeled using a novel technique developed by us rec~tly. Our results show a rat

β¦ Synopsis
Two effects give rise to osmosis in a permeable membrane: the coupling effect between the ion streams and water, demonstrated by binary isotonic osmosis, and the osmotic difference between the outside solutions. But, in contrast to a semipermeable membrane, it is not the difference in the outside concentrations but the difference in the Donnan ions inside the membrane that produces the flux of water.

The permeate flux, permeate concentration, brine flux, and brine concentration have been experimentally determined. A pilot-scale reverse osmosis configuration consisting of 18 tubular-type cellulose acetate membranes has been used for the desalination of brackish water. The transport parameters (i.
