Abstract |
The objectives of the investigation were to: (1) determine the seasonal variations in sludge stabilization and reductions in the densities of indicator organisms, Salmonella ssp., and enteroviruses that occur with conventional aerobic digestion in cold climates; and (2) demonstrate that both sludge stabilization and reductions in the densities of these microorganisms can be improved by simple modifications that increase process temperature. Two 32 cu m aerobic digesters located at a small municipal wastewater treatment plant were operated continuously over a period of 20 months to obtain the data necessary to satisfy these objectives. One digester was a conventional digester while the other was designed to minimize heat losses and thus, facilitate autoheating. |
