Title: Methane emissions from municipal wastewater treatment processes

Abstract

Methane and carbon dioxide emissions from primary and secondary wastewater treatment processes were measured from mid-winter to summer conditions in Durham, NH. A statistically significant positive relationship between gas flux and wastewater temperature was determined for methane and carbon dioxide in both the aerated and nonaerated areas of the grit tanks. Statistical correlations to temperature measured in a secondary aeration tank were marginal for methane and insignificant for carbon dioxide. Emission factors derived from our measurements were 39 g of CH[sub 4] person[sup [minus]1] year[sup [minus]1] and 35 698 g of CO[sub 2] person[sup [minus]1] year[sup [minus]1] for primary and secondary activated sludge treatment processes. 14 refs., 4 figs., 2 tabs.
