Abstract: In the present investigation, the wastewater treatment plant (WWTP) of industrial zone of Amol which works with anaerobic system using Up flow Anaerobic Fixed Bed (UAFB) and aerobic system using Integrated Fixed Activated Sludge (IFAS) was studied. In order to measure the amount of energy consumed by the treatment plant, the electricity bills for the different months of 2012 and 2013 were checked and the average daily consumption of electric energy per 1 cubic meter of effluent calculated during these years was 6.62 kwh and 6.24 kWh, respectively. Furthermore, the electromechanical equipments of the plant in each unit were examined separately. The effective daily electrical energy that is the energy used in the treatment process was 4.45 kWh. In addition, the amount of electrical energy per 1 kilogram removed chemical oxygen demand (COD) was obtained. Regarding the energy consuming treatment plant equipments and the rapid increase in energy (electrical energy) prices, the energy management should be more seriously concerned.
