A method and apparatus for separating oil from water in a raw mixture in which the mixture enters a separator tank having within it electrodes to which an A.C. voltage is applied to cause separation of the oil and water. In one embodiment, two sets of electrodes extend to different lengths in the tanks with a high voltage being applied to the shorter electrodes and a low voltage to the longer. A valve can be disposed in the water outlet pipe to be opened to drain water whenever the sensed conductivity near the tank bottom exceeds a given value. The tank can be immersed in a larger tank and can be provided with porous walls through which the raw mixture enters and the separated oil and water leave. The electrodes can comprise a center electrode and a plurality of high voltage electrodes disposed about said center electrode with a high voltage then applied between said center electrode and the circumferentially disposed electrodes. |
