Abstract (en)

The present invention refers to a washing method for centrifugal separators of mixtures composed of two liquid phases with different specific gravity and solid and non-solid sediments. The said method includes two washing phases and one phase is performed keeping the overflow opening for the exit of the liquid phase with higher specific gravity closed.
