Abstract

This invention relates to a sewage sludge treatment system resulting in an oxygenated and/or ozonated treated sludge containing substantially no pathogens. The system includes apparatus (10) and a process for mascerating raw sludge, adjusting the pH to about 2.5 to about 3, adjusting the solids content to about 2.5% to about 4%, adjusting the temperature, if necessary, to about 20°C to about 40°C, mixing an oxygen-rich gas, such as oxygen and/or ozone with the sludge as the sludge is mixed or recirculated through a hyperbaric vessel (12) and simultaneously injecting the oxygen-rich gas into a combination gas and sludge mixing and dispersing assembly (30) in an upper portion (16) of the hyperbaric vessel (12). Such injection causes mixing of the gas and sludge and dispersement of such mixture in a plurality of streams (76) to atomize and oxygenate the sludge.
