Abstract
A process and apparatus for treatment of sludge is provided. The process includes providing sludge in a substantially liquid form and an alkaline additive to a preferably substantially closed reactor vessel, mixing the sludge and additive to ensure said pH is greater than about 12, maintaining the pH for a predetermined period of time, optionally applying supplemental heat to the sludge mixture in the reactor vessel to a predetermined elevated temperature for a predetermined period of time, maintaining the sludge mixture in a substantially fluid liquid condition, and discharging the sludge and additive mixture from the reactor vessel in a substantially liquid form such that it lends itself to be handled by gravity flow. The apparatus provides means to accomplish the above process.
