A method of operating a system for de-oiling water utilising hydrocyclone separators (9). Each separator (9) has a mixture inlet, an overflow oil outlet (10) and underflow water outlet (11). The flow through at least one hydrocyclone (9) is sensed and, if the flow approaches a threshold below which there is insufficient flow through the respective hydrocyclone (9) for satisfactory operation, an additional supply of water is fed to the mixture inlet. |
