Abstract:

Since the 40 CFR, Part 503 regulations1 were promulgated in 1993, utilities and engineers have considered thermophilic anaerobic digestion configurations to produce Class A biosolids from municipal wastewater sludges. As thermophilic anaerobic digestion is not listed in the regulation as a process to further reduce pathogens (PFRP) other options have been used in order to achieve Class A biosolids. The most viable options are:

Alternative 1: Time and Temperature


Alternative 3: Documented Virus and Helminth Ova Destruction


Alternative 6: Treatment with an PFRP-Equivalent Process
