ABSTRACT:
Decantation tanks receive an oil-water mixture from a holding tank. These decantation tanks are set at varying elevations and are arranged to operate in series to drain off oil that has separated out. These tanks may have heat producing elements associated therewith to increase the efficiency of oil separation, and chemicals may be employed in these tanks also to increase such efficiency if necessary. Separator tanks are also provided in the system and receive oil-water mixture from the bottom of the decantation tanks for further separation of oil from the water. These separator tanks have a skimming apparatus therein and also have a pair of baffles under which the water must travel to accomplish further separation of the oil. The separator tanks have a cross partition, and water in a main portion of the tank flows over such partition to a rear compartment from where it is directed to an open top inspection tank and filtered. The pH of the effluent may be altered at this point if necessary. The water upon discharge from the inspection tank is substantially oil free and is then directed into a waste water pond for disposal. The system employs an extensive manifold arrangement between the various elements for by-passing, recirculation, etc.
