Abstract
An oil and water separator is disclosed having plural nested separating tanks. An oil/water mixture is introduced into the innermost tank. A fluid exchange means, such as a corrugated pipe wound to form a helix, transfers fluid from the innermost separating tank through successive separating tanks to the outermost tank. The majority of oil is trapped within the innermost tank and is transferred to a recovery tank by an overflow device. In outer separating tanks, a biological digestion of the small amount of remaining oil takes place.
