Abstract
The results of a study of four years' operation of a multiple-stage sludge digestion system are presented in this paper. Satisfactory results have been obtained with a detention period of ten days. The division of the process into stages has afforded an opportunity to obtain data on the component phases of digestion. Part I includes a quantitative study of operating data. This is followed, in Part II, by a report of research on some chemical phases of sludge digestion. Gas, sludge, and sludge liquor analyses and a discussion of chemical equilibria are included. The presence of traces of unusual compounds in sludge and sludge gas has been verified by micro-analyses.
