ABSTRACT:
The invention relates to a method of, and system for, degassing a mixture of a liquid first material, e.g. white water, and at least one second material, e.g. paper-making stock, the mixture being regeneratively pumped through cleaning means, e.g. a vortex cleaner, to an aeration tank. The regenerative pumping may be controlled to control the sub-atmospheric pressure applied to, and the liquid level in, the aeration tank.
