Abstract

The greenhouse gases, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) can all be produced in wastewater treatment operations. Major progress has been encountered for estimating (N2O) and (CH4) emissions from wastewater treatment plants, yet, limited number of studies considered CO2. One problem with the mass balance technique in the Activated Sludge lies in satisfactorily measuring waste activated sludge volumes and in obtaining representative samples for analysis. A traditional mass balance approach for analyzing the performance of the activated sludge secondary clarifier does not account for variations in sludge depth and suspended solids concentrations within different layers. In turn, a gap in knowledge is present in closing the Carbon mass balance within the Activated Sludge system. In this essence, the main focus of this research is to quantify the carbon dioxide emissions from the Aeration Tank in the biological treatment. This will be achieved by generating a full-scale of accurate measures to precisely simulate the SC behavior aiming at determining the fate of the CO2 through the Activated Sludge system. Results from this research attained a reasonable carbon balance closure of 95%.
