• Reverse osmotic concentration of aqueous dimethylsulfoxide and aniline solutions was carried out using composite membranes and cellulose acetate asymmetrical membranes. Separation of DMSO and aniline, and flux through the membrane were measured within the following ranges : conc. of DMSO ; 1.5, 3.7, 6.1 wt%, conc. of aniline ;.35, .75, 1.4wt%, operating pressure 4, 5, 6 Mpa.<BR>PEC-1000 gave the best separation. After RO separation of aqueous aniline solutions, pure water permeation was reduced remarkably with a few exception of the case using ON membrane.<BR>Membrane constants were calculated by Spiegler-Kedems transport model. The deviation from their model was corrected by compaction coefficients. Estimated saparations and fluxes were almost the same as experimental value.
