ABSTRACT:
Oil and other contaminants are separated from aqueous effluents by a system which includes means for introducing the contaminated aqueous effluents into a separation zone where they are passed through the labyrinth course of a coalescing chamber to separate oil particles. The oil is removed by means of a skimmer and moved into an oil storage area. The aqueous effluents are then passed from the bottom of the separation zone to an extraction zone where they are passed through a bed of a material capable of adsorbing hydrocarbons and other pollutants. The effluent may then be discarded or may be moved through a fail safe system designed to assure that hydrocarbon removal is complete in all instances.
