Abstract
Regulations for land application of wastewater sludges require the performi ng 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 thermophilic/mesophilic Two Phase Anaerobic Digestion proce ss. According to the EPA 40 CFR 503 regulation, the process produces Class A biosolids and could be recommended as a Process to Further Reduce Pathoge ns.
