چکیده مقاله
The design and implementation of eco environmental wastewater treatment plants WWTPs is required due to the acceleration of carbon emission To minimize the carbon impacts, life cycle assessment LCA can be an appropriate technique for comparing WWTPs considering energy supply and carbon release Although more literature focused on biological phosphorus removal systems, however, their carbon footprint and energy consumption are less investigated Therefore, Step Bio P, anaerobic/anoxic/oxic A2O , and Bardenpho systems were simulated and optimized operationally The Step Bio P showed high efficiency for COD 91 71% and nutrient >77% removals while its energy demand indicated an increase of 1 4 to 1 8 fold Regarding carbon footprint, the Bardenpho system led to the highest release of CO2 which was associated with fossil fuel utilization in electricity production However, almost 10 83% to 39 97% of overall energy consumption can be recovered by the combined heat and power CHP and boiler installation Moreover, the development of green energy sources has an influential impact on the reduction of carbon emissions However, more performance assessments and LCA evaluations of WWTPs at the unit process level are still required to identify and improve the system hotspot
