Beschreibung
Zusammenfassung:	A process and apparatus for treating biosolids from biological wastewater treatment. The temperature of autothermal aerobic treatment of biosolids is controled by sensing the oxidation/reducti on potential of the solution and adjusting the amount of oxygen or biosolids supplied to the solution through a jet aerator (1) havin g a liquid header (3) for the recirculation of the solution and an air header (5).
