Digestion of sewage sludge by aerobic processes
Abstract
Scope of Study: The purpose of this report is to determine the degree to which sewage sludge can be digested using aerobic processes. The degree of digestion is measured as the per cent reduction of volatile solids, reduction of total solids content, and drainability. The influence of the method of feeding is also studied. Findings and Conclusions: The laboratory results showed that the degree of digestion of sewage sludge that can be accomplished aerobically is dependent on several factors. It was concluded that the reduction of volatile solids is a function of the detention time, temperature of operation, and method of adding raw sludge to the digester.
