Results Section of Hick’s Thesis on “Modeling Greenhouse Gas Emissions from Conventional

Wastewater Treatment Plants in South Carolina”

Representative Plant: Process Emissions

Representative Plant: Power Emissions

From previous slide, process emissions = 0.279 CO2e g/L which is close to emissions from energy
