<p>Improved techniques are provided for separating mixtures of materials having different densities. The disclosed apparatus separates oil from water, and includes a separation tank (52) defining a cylindrical water storage chamber (54) and a frustoconical separation chamber (56) spaced above and adjoining the water storage chamber. Fluid is input to the separation tank at the level of the oil/water interface. An oil leg (58) is spaced above the separation chamber. Adjustable overflow units (60, 70) are provided to 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.</p> |
