Abstract
In a method of operating a bank of parallel hydrocyclone separators for deoiling water, each separator has a mixture inlet, an overflow oil outlet and an underflow water outlet. The flow through at least one separator is sensed, either directly, or indirectly by sensing the pressure difference across the separator. If the flow approaches a threshold below which there is insufficient flow for satisfactory operation, an additional supply of water is fed to the mixture inlet fo the separators.
