ESTIMATION OF METHANE EMISSIONS FROM DOMESTIC WASTEWATER IN CAU RIVER BASIN BY 2030

The Cau River basin has recently raised significant concerns about associated pollution issues and their critical role in socio-economic development. This study aims at assessing and forecasting the impacts of domestic wastewater on the generation of greenhouse gas emissions in Cau River basin in 2030. The main methods have been applied in this study including data collection and analysis, synthesization and inheritance method of research documents. Moreover, the study has calculated the amount of greenhouse gases from wastewater in the Cau River basin basin from the use of septic toilets, other toilets and centralized wastewater treatment plant based upon the guidance of the IPCC (2006). The results show that the CH4 gas is mainly generated from the anaerobic treatment of domestic wastewater with total CH4 emissions for the scenario up to 2030 at 234,337.91 Gg CH4/year (accounting for 95.3%) of the total amount (corresponding to 245,818.59 Gg CH4/total kg of BOD) emitted when applying treatment measures.
