PCT No. PCT/EP90/00514 Sec. 371 Date Oct. 17, 1991 Sec. 102(e) Date Oct. 17, 1991 PCT Filed Mar. 31, 1990 PCT Pub. No. WO90/11810 PCT Pub. Date Oct. 18, 1990.A process for the separation, by sedimentation, of at least one liquid organic component dispersed in a liquid containing mainly organic materials, this organic component and the remaining liquid exhibiting a difference in density. In order to reduce considerably the standing time, it is proposed that the liquid be passed before sedimentation through a fiber bed that the organic component and the remaining liquid have different surface tensions with respect to the fiber bed, that the temperature of the liquid and the concentration of the organic component to be separated are such that, in the equilibrium state, at least two liquid phases form, and that the rate of flow of the liquid through the fiber bed lies below a maximum value dependent on the surface tension of the organic component with respect of the fiber bed and on the difference in density and surface tension between the remaining liquid and the organic component.
