The circulation tank has an interior height which is configured such that a chamber exists inside the tank above the level of the liquid. Alternatively, the circulation tank inlet is permanently positioned above the liquid level or it includes a pipe configured such that the dispersion forms a film on its inner surface. Alternatively, the circulation tank includes an impeller having a diameter equal to or greater than 0.5 times the internal diameter of the tank.
