ABSTRACT:
A system for disposing of sewage sludge by treating the sludge in apparatus which processes the sludge through relatively inert gas drying and grinding stages and utilized as much of the dried and ground sludge as is needed to produce heat for maintaining the drying process in the system once the system has become substantially self sufficient on use of the sludge as the drying heat source. The remaining excess sludge is then in a form either granular or fine suitable for direct sale.
