Abstract

The disclosure concerns a method for separating an oil-containing aqueous liquid mixture having an oil content of ≤ 5% into an aqueous heavy phase and a light phase in a separation system (32). The method comprises:- conducting the liquid mixture from a tank (34) via an inlet conduit (36) to an inlet passage (22) of a centrifugal separator (2),- separating the liquid mixture into the aqueous heavy phase and the light phase in the centrifugal separator (2),- determining an oil concentration parameter of the light phase, andin response to the oil concentration parameter exceeding a threshold,- conducting the light phase from a light phase outlet passage (24) to a container (38) for light phase, and in response to the oil concentration parameter falling below the threshold,- recirculating the light phase from the light phase outlet passage (24) to the inlet passage (22).
