Abstract: 

Reaction constants and heat release during thermophilic aerobic digestion of typical secondary and mixed bio-solids (sludges) were determined. Maximum reaction constant occurred in the temperature range of 55-60oC. By the aid of a temperature P.L.C., measurement of heat releases were carried out. An amount equal to 16.2 KJ/g-cell was measured for secondary sludge digestion. Cell growth in mixed sludges provided an extra heat equal to 6.7 KJ/g-cell.
