| Abstract |
The project objective was to investigate pathogen inactivation in lagoon-stored municipal sludges. The in-field lagoons were located in Louisiana (New Orleans) and in Texas (Port Aransas), both semitropical areas of the United States. Each lagoon was filled with 7.56 cu m of anaerobically digested sludge to which a spike containing a mixture of Salmonella livingstone, poliovirus Type 1, and Ascaris suum eggs was added. The field and laboratory data demonstrated that 15 mo of storage was required for pathogen inactivation to meet the U.S. Environmental Protection Agency's (EPA) Process to Further Reduce Pathogens (PFRP) criteria for lagoon-stored sludges in a semitropical climate. In the study, viable Ascaris eggs were inactivated in 15 mo in the New Orleans lagoon where the temperature averaged about 25 C over a 5 mo period. Salmonella livingstone was inactivated in 4 to 6 mo in both lagoons at a log-reduction rate of 1.2 and 1.6 log Most Probable Number (MPN)/mo/100 ml in New Orleans and Port Aransas sediments, respectively. Total coliforms and fecal coliforms declined 2 to 6 logs within 12 mo. |
