ABSTRACT:
Oil-containing effluent is treated by passing it through a gravity separator and obtaining (a) a wet oil fraction, (b) an aqueous fraction of reduced oil content and (c) a wet oily sludge. Fractions (a) and (c) are then combined and passed through a pressure filter so that solids are retained and oil and water passed through. The oil and water are then passed to a separator and a reusable oil fraction is recovered and a water fraction which is returned to the gravity separator.
