Abstract: A method and apparatus for separating an oil phase from an aqueous phase by means of a rotating drum apparatus containing one or more compartments, each being partially filled with oleophilic free bodies. When containing two or more compartments, they are separated by an apertured baffle. The interior surfaces of the drum are oleophilic and the portion of the drum sidewall, where the mixture is removed is apertured. Due to the oleophilic free bodies and interior oleophilic surfaces, the aqueous phase velocity through the drum is faster than the oil phase which adheres to the oleophilic surfaces causing an in situ buildup and agglomeration of oil phase in the drum. The mixture exiting the apertured drum sidewall is partitioned by the tumbling free bodies, oleophilic drum surfaces and drum rotation such that aqueous phase leaves the drum between the 6 and 9 o'clock positions of counter clockwise rotation where free body concentration is minimal.
