PROCESS AND APPARATUS FOR TREATING BIOSOLIDS

A process and apparatus for treating biosolids from the biological treatment of wastewater. The temperature of autothermal aerobic treatment of biosolids in a reactor (33) is controlled by adjusting the amou nt of shear generated through jet aeration devices (35) by varying the flow through the pump...

Beschreibung
Zusammenfassung:	A process and apparatus for treating biosolids from the biological treatment of wastewater. The temperature of autothermal aerobic treatment of biosolids in a reactor (33) is controlled by adjusting the amou nt of shear generated through jet aeration devices (35) by varying the flow through the pump (37). A method and apparatus for controlling foam generated in a treatment reactor is also disclosed.
