A method has been invented for separating components of a wastewater stream, the stream containing water, oil (e.g. heavy oil and/or light oil), undesirable organic material (solid and/or liquid), and contaminating solids, the method including feeding a wastewater stream to a first pre-treatment unit producing a first pretreated stream, feeding the first pretreated stream to a first centrifuge for centrifugal separation, producing a first liquid centrifuged stream, and a second liquid stream, and feeding the first liquid centrifuged stream to a second centrifuge producing a resultant centrifuged stream of recoverable oil and a water phase centrifuged stream which can be treated further or fed back to a source for re-use. The source may be a facility from the group including refineries, chemical plants, paper mill plants, and oil and gas processing facilities.

Methods for wastewater treatment

A method and a system for the treatment of organic hazardous wastes from plant waste and associated wastewater treatment processes, whereby the waste is either introduced directly, or continuously separated from wastewater, and routed to a bioreactor, and whereby no organic solids are generated for further offsite disposal. The system disclosed includes a bioreactor, containing selected bacteria, untreated sludges, and recirculated biomass, and a liquid/solid separator allowing water to be utilized elsewhere in the system and returning solids to the bioreactor. The biodegradation process, initiated continuously, converts hazardous organic constituents in waste stream and wastewater sludges from plant operations to inert materials, for extensive periods of operation, without the need for solids removal, external solids treatment or disposal.
