| Abstract |
The effectiveness of the dual digestion system (DDS) to destroy pathogenic microorganisms was evaluated at a full-scale treatment facility. The DDS incorporates a pure oxygen aerobic digester (1-day detention time) followed by an anaerobic digester (8-day detention time). Heat biological oxidation is conserved in the aerobic step to achieve thermophilic temperatures. Destruction of three pathogen indicators (total coliform, fecal coliform, and fecal streptococci) and a pathogenic bacteria (Salmonella spp.) were measured during three 10-week sampling periods. Conventional measures of digester performance were also analyzed. The performance of DDS in producing a stabilized, pathogen-free sludge was compared to accepted pathogen reduction technologies.
