Apparatus for separating oil from an oil/water mixture
First Claim
1. Apparatus for separating oil from an oil water mixture comprising a settlement chamber, a coalescing filter, an entry port comprising a means for introducing the mixture initially into the coalescing filter for flow therethrough into the settlement chamber, an oil outlet opening from an upper region of the settlement chamber, a sorbent bed contained in a second chamber, a water outlet from a lower region of the settlement chamber through which water may flow to the sorbent bed, a water outlet from the sorbent bed at a level below the oil outlet opening, said coalescing filter including a cylinder of filter medium depending from a closed top of the settlement chamber with the axis of the cylinder substantially vertical, and the entry port opening into the interior of the cylinder through the top of the settlement chamber.

Abstract
Apparatus for separating oil from an oil/water mixture. The mixture is introduced into a vessel through entry ports and passes through a coalescing filter, flowing therethrough into a settlement chamber. Separation of oil and water occurs in the chamber and oil flows therefrom through an outlet to a waste collection vessel. Water is taken from the lower part of the chamber through a pipe and passes through a sorbent bed prior to discharge through an outlet located at a level below the level of the oil outlet opening.
