ABSTRACT:
The present invention relates to an apparatus and process for treating sewage sludge in which the sludge preferably has its pH adjusted to an acidic range. Then the sludge is conveyed to a vessel having an oxygen-rich atmosphere. The sludge is channelled through two different dispersing means by which it is comminuted and dispersed throughout the oxygen-rich atmosphere where it is completely oxygenated. To assure that the sludge is completely oxygenated, preferably it is caused to travel through two separate angles in the oxygen-rich atmosphere, each being greater than 90 degrees.
