The process of removing organic components from wastewater as BOD5 through wastewater treatment plants has been proven to be a significant source of greenhouse gas emissions, mainly methane CH4, carbon dioxide CO2 and nitrous oxide N2O. The reduction of these emissions has attracted more interest given their major contribution to global warming. This study was able to identify and estimate the amount of methane and CO2 emissions on a monthly basis by a simple modeling approach and an empirical method (IPCC) for N2O emissions, in the case of Ain-Taoujdate wastewater treatment plant, throughout the years 2013, 2018 and 2019. The results showed that anaerobic ponds were the main source of on-site emissions with 66% of total contribution and 33% for facultative ponds, followed by the energy consumption of the pumping station as off-site GHG emissions.

Domestic Wastewater Treatment

Domestic wastewater treatment plant (WWTP) is one of the entities that emit the greenhouse gas (GHG) to the environment because of microbial breakdown of the organics in human waste, and the use of electricity to operate the treatment plant itself. The first GHG inventory in Malaysia has provided a good foundation for the development of a more comprehensive national inventory. However, due to the lack of detail data from actual plant, Malaysia can only produce imprecise estimates for domestic wastewater. Therefore, there is a need to develop a proper database since based on various real plant characteristics and operating conditions, the actual values of GHG emissions from domestic wastewater in Malaysia could be different from other countries. In this study, a new inventory system has been developed to estimate GHG emissions by domestic WWTP, resulting from direct and indirect activities. Referring to the Intergovernmental Panel on Climate Change approach in 2006, the inventory is started for Imhoff tanks, which constitute 12 percent of all domestic treatment plants in Malaysia. The inventory gives preliminary overview on estimation of GHG emissions from onsite domestic treatment plant when treating wastewater for different Population Equivalent (PE) and Biological Oxygen Demand (BOD) loading.
