Biochemical methane potential (BMP) test were used to assess the methane production. A full-scale digester evaluation was done by using the ADM1 model. The best results in the BMP assays were obtained at 180 C and 200 C both at 30 min. The inclusion of a thermal inter- treatment unit is feasible in a full- scale plant. article i nfo abstract Article history: The conventional application of thermal pretreatment of sewage sludge has been to apply it prior to the Received 25 February 2016 anaerobic digestion.
