ABSTRACT:
A method and related apparatus are disclosed herein for controlling the quantity of oil as a contaminant being discharged with water from a hydrocyclone. The hydrocyclone comprises a conical body with an upper liquid mixture inlet, a drive fluid inlet, an overflow outlet for the separated oil and drive fluid, and an underflow outlet for the separated water. The method includes monitoring the quantity of separated oil with the discharged water and varying the quantity of the drive fluid introduced into the interior of the hydrocyclone whereby the quantity of the oil as a contaminant is minimized.
