ABSTRACT:
Oily water is introduced into the lower ends of outer vessels and flows upwardly in annular spaces between the outer vessels and inner separating vessels and into the inner vessels below inwardly spaced, shallowly cupped, annular separating discs. Larger particles of oil flow past the discs directly to the tops of caps on the outer vessels. The smaller particles of oil coalesce on and flow slowly along the bottoms of the discs to central openings in the discs, and up into the caps. The oil flows out of the caps when valves are opened by ultrasonic sensing probes actuated by accumulation of predetermined quantities of oil in the caps. The water flows out of outlets positioned near the bottoms of the inner vessels. In an alternate embodiment, a filter member of foam plastic is inclined to the flow toward the water outlet and coalesces any oil yet remaining in the water.
