A method and apparatus are provided for separating oily particles from an emulsion thereof in an aqueous liquid. The emulsion is passed through a bed of oleophilic granules supported on a foraminous support, the oleophilic granules, by virtue of their density, pressing against the foraminous support and the bed is unconfined downstream thereof so that the granules in the bed are fluidized by the passage of liquid therethrough. The oily particles are removed from the emulsion by the oleophilic granules in the bed, and the oily material accumulates and agglomerates and is transported out of the bed by the passage of liquid therethrough. The movement of the liquid then carries the oily droplets which are formed in the bed and deposits them upon a screen positioned downstream of the bed, the aqueous liquid passing through the screen in purified form. The oil accumulates on the screen and is propelled by the moving liquid into an oil reservoir positioned downstream of the screen.
