Abstract:

Eight types of Class A biosolids were tested for the potential of fecal coliform regrowth at 20, 35 and 50 °C for 21 days. Regrowth of fecal coliforms (FC) did not occurr at 20 or 55 °C, but it was observed in two samples incubated at 35 °C after a lag period of 48 hours. In a sample of undigested biosolids, final FC concentration exceeded 104 CFU/g whereas in the thermophilic biosolids, final FC concentration remained below 103 CFU/g as FC regrowth was affected by the presence of the anaerobic bacterial consortium. FC regrowth within treatment plant operations seems unlikely but may occur in land application of biosolids.
