Abstract : Theoretical and practical aspects of reverse osmosis and diffusion are reviewed and discussed, with special emphasis on methods of determining diffusion constants and permeation constants. Small scale osmosis experiments were designed to yield useful data applicable to reverse osmosis systems. Measurements were made of diffusion constants and permeation constants for both water and NaCl in two kinds of cellulose acetate and also in Nylon-6 membranes. The results compared very well with those found in the literature for reverse osmosis. (Author)
