Abstract
The present invention relates to an apparatus for treating sewage sludge in which the sludge is conveyed to a vessel having an oxygen-rich atmosphere. The sludge is channelled through a first dispersing means to a plurality of second dispersing means by which it is dispersed throughout the oxygen-rich atmosphere where it is completely oxygenated. Preferably, the first dispersing means comprises separable components which define the channelling means. Preferably, the second dispersing means are aligned with the channelling means and either arranged around the inner periphery of the vessel, or attached to the first dispersing means.
