Wastewater Process Emissions Fundamentals


Treating wastewater and sewage sludge produces direct greenhouse gas emissions, including methane and nitrous oxide, which have far greater warming potential than carbon dioxide. As society increasingly adopts renewable energy sources over fossil fuels, these emissions are expected to become the leading source of greenhouse gas emissions for wastewater utilities. 

This expert-led webcast series is designed for wastewater professionals looking to deepen their understanding of greenhouse gas (GHG) emissions from wastewater treatment processes. Consisting of four 1-hour sessions, the series will cover the types and sources of GHGs from wastewater treatment, the process conditions and mechanisms that drive these emissions, real-world approaches to measuring, monitoring, and quantifying these emissions, and practical strategies for reducing them.  

This first webcast in the series provided an introduction to greenhouse gas (GHG) emissions in wastewater treatment with a focus on various emission sources, the pathways and process conditions that lead to emissions, and quantification and measurement techniques. Presenters identified and explained the significance of various sources and pathways of GHG emissions at wastewater treatment facilities. Basic techniques for measuring and quantifying GHG emissions at wastewater treatment facilities were also be explored.
