The two phase anaerobic digestion process: sludge stabilization and pathogens reduction
Keyword(s):
Regulations for land application of wastewater sludges require the performing of treatment with a high efficiency on pathogens reduction. a reduction of 61% of the Volatile Solids content of the sludge, a reduction of fecal coliform, polio virus and Ascaris egg of 5.5, 4.0 and 2.6 respectively are achieved with a thermmophilic/mesophilic Two Phase Anaerobic Digestion process. According to the EPA 40 CFR 503 regulation, the process produces Class A biosolids and could be recommended as a Process to Further Reduce Pathogens.
