Abstract
A lime stabilization system for treatment of sewage sludge, and method is provided in which dewatered sludge and lime are provided to a mixer. Lime and sludge are mixed to raise the pH during which volatiles are driven off with or without supplemental heat. A forced air draft prevents steam from backing up into the lime supply. The sludge goes to a discharge station via a transfer apparatus, and air containing any dust, odors, steam or ammonia is cleaned via a scrubber. The system is computer-controlled via gravimetric load cells and/or volumetric means. The system includes computer controlled means for dissolving scale resulting from exposure of surfaces to lime, using acid, water or combinations thereof.
