Water and salt fluxes through synthetic membranes were measured as functions of pressure. In the pressure range 0–60 atm. both the water permeation rate constant and the salt permeation rate constant were independent of pressure. The water flux increased linearly with pressure driving force (hydraulic‐osmotic). The changes in salt flux were small. These changes were proportional to changes in the activity of the salt solutions due to concentration and pressure effects. Good agreement was obtained between the experimental flux data and the kinetic equations describing the process.
