Abstract
A physical model system was developed to permit measurement of heat evolved during the composting of sewage sludge, and to remove heat through ventilation and conduction in a manner realistically comparable to field scale systems. Heat evolutions of approximately 15,000 to 22,000 Joules per gram decomposed were observed, with peak outputs of almost 700 J/g initial sludge volatile per 12 hour period. Composting activity appeared to be enhanced by ventilation, independent of temperature or high interstitial oxygen concentration, but possibly related to particle surface turbulance factors improving oxygen transfer.
