Abstract
The invention concerns a device for reducing the content of solid impurities in a process liquid comprising a hydrocyclone (1) with a tangential inlet (2), a container for separated material (3) and an outlet pipe for purified liquid (4), wherein the outlet pipe (4) of the hydrocyclone for purified liquid contains a further coaxially arranged outlet pipe (5) for a second purified liquid fraction. In addition the invention concerns the use of such a device for purification of process liquids from a continuous digester and a process for cleaning of a process liquid from a continuous digester.
