Abstract
An oil recovery system, designed to recover oil from oil-contaminated water of a river, lake or sea due to a difference in specific gravity of the liquids. The system includes a 4-stage separation tank having four chambers . The first chamber includes a hopper-shaped oil floating unit in communication with a piston pump (FIG. ) and having porous filters therein. The second and third chambers include a plurality of horizontal diaphragms for reducing the processing time for separating oil from water. The system can be continuously operated without being stopped during an oil recovering operation. The oil recovered from discharged pipe is usable so that the system preferably conserves natural resources.
