Arrangement for the self-sufficient regulation of liquid levels in a plastics recycling process

An arrangement for the self-sufficient regulation of liquid levels in a plastics recycling process, comprising:

• at least one compensation container and at least one stirring container which has a stirring device which rotates about a substantially vertical axis, wherein the compensation container and the stirring container are filled with a process water, so that the compensation container has a first liquid level and the stirring container has a second liquid level, wherein the at least one compensation container is fluidically connected to the stirring container, so that the process water can flow freely between the compensation container and the stirring container, as a result of which the first and the second liquid level of the at least one compensation container and of the at least one stirring container are the same, wherein at least one hydrocyclone is arranged downstream of the stirring containers in terms of process technology.
