ABSTRACT:
A process and apparatus for separating liquids of different specific gravities, and more particularly for separating oil from water. The oil-contaminated water is pumped by a low emulsifying pump from a storage site to an oil gravity separator where a substantial portion of the oil is separated by gravity from the water. The water is then delivered from the gravity separator to a regenerative filter composed of a plurality of layers of granular media which serve to remove foreign materials and the remaining oil from the water. The clarified water can then be discharged to a discharge site. The oil-separator vessel includes an upper oil collection zone, and a capacitance-type sensor is responsive to the level of oil in the collection zone and operates, when the oil reaches a pre-set maximum level, to close a valve to prevent water flow to the regenerative filter, while opening a drain valve to permit the oil to be discharged from the separator vessel by the pump to an oil recovery tank. With the invention, a single pump is utilized to alternately pump the clarified water to the water discharge site, and to pump the collected oil sludge to the oil recovery tank without undue emulsification of the incoming oil-contaminated water.
