AI Article Synopsis
- This study estimates greenhouse gas emissions from aerobic and anaerobic Wastewater Treatment Plants (WWTPs) in Southern Italy, focusing on different emission factors.
- It finds that emissions vary, with anaerobic plants emitting 73 kgCO/PE*y and aerobic plants emitting 91 kgCO/PE*y, highlighting the significant role of nitrogen and carbon emissions.
- The research identifies that nitrogen oxide (NO) emissions are the primary contributor to greenhouse gases, while measures to reduce these emissions are also discussed.
Article Abstract
The present work has estimated greenhouse gas emissions in aerobic and anaerobic Wastewater Treatment Plants in Southern Italy. Greenhouse gases emissions from each treatment unit were calculated based on emission factors related to Chemical Oxygen Demand removal for biogenic CO and CH assessment and on Nitrogen removal for NO. NO, biogenic CO and CH emissions vary for aerobic and anaerobic-based WWTPs respectively from 73 kgCO/PE*y for anaerobic plants to 91 kgCO/PE*y for aerobic plants. In aerobic and anaerobic digestion systems WWTPs the contributions to CO total emissions from NO, CH, biogenic CO, and fossil CO are 30 %-33 %, 20 %-29 %, 22 %-25 %, and 26 %-16 %, respectively. NO emissions from biological processes were found the most contributing sources of greenhouse gases while in the physical processes higher contribution is indirect carbon dioxide related to energy consumption. Compensatory measures are reported to reduce greenhouse gases emissions.
