Abstract In this study, the process performance in terms of effluent quality, the sludge production and the biogas potential was simulated and compared with the data of real wastewater treatment plant with the capacity of 1,400,000 PE in Antalya, Turkey. The energy content of undigested primary and biological sludge were measured to be 16.33 MJ/kg (3,900 kcal/kg) and 13.21 MJ/kg (3,155 kcal/kg) of sludge on dry basis. The thermal and electrical energy production generated form sludge was examined by using annual data. In addition, the energy balance in the system was evaluated by incorporation of additional sludge disintegration, anaerobic digestion and sludge incineration processes. The energy generation through biogas production and heat recovery from incineration was thoroughly evaluated in combination with simulation based on process analysis.
