Greenhouse Nitrogen Emissions from Wastewater Treatment Operations – Phase II: Molecular Level through Whole Reactor Level Characterization
Abstract
This project continued the research into microbiological pathways involved in the formation and emission of nitrous oxide (N2O) from wastewater treatment processes in Phase II by building on previous work by the project team (WERF U4R07). This report focuses on the impact of process conditions such as glycerol-based denitrification in a full-scale nitritation-denitritation process, anoxic-oxic cycling, and inorganic carbon limitation. Because plant operations have a key role in N2O emissions, the report provides insight into the mechanisms influencing emissions and direction to ultimately create environmentally sustainable BNR operating strategies and configurations.
