Extended Acid Digestion for Inactivation of Fecal Coliforms
The objective of this research was to establish a correlation between inactivation of fecal coliforms caused by organic acids in their un‐ionized form in batch acid digesters and semicontinuously fed acid digesters at both mesophilic (38°C) and low‐mesophilic (24°C) temperatures. Batch acid digesters achieved a U.S. Environmental Protection Agency Class A level of fecal coliforms within 6 to 7 days of digestion at both temperatures. Semicontinuously fed, staged, acid‐digestion systems achieved Class A standards on average only at mesophilic temperature at a solids retention time of 11 days. Systems operated at low‐mesophilic temperatures did not achieve Class A standards.
