ABSTRACT:
Improved techniques are provided for separating mixtures of materials having different densities. The apparatus of the present invention is well suited for separating oil from water, and includes a separation tank defining a cylindrical water storage chamber and a frustroconical separation chamber spaced above an adjoining the water storage chamber. Fluid is input to the separation tank at the level of the oil/water interface. An oil leg is spaced above the separation chamber, and an adjustable oil overflow unit is provided adjacent the oil outlet for selectively varying the head pressure of oil in the oil leg. A water leg is provided in parallel with the separation tank, and an adjustable water overflow unit is provided adjacent the water outlet for selectively varying the head pressure of water in the water leg. The adjustable overflow units allow the head pressure in the oil leg relative to the head pressure in the water leg to maintain the interface within the upper portion of the separation chamber. Sensing means are provided for monitoring the elevation of the oil/water interface within the separation chamber.
