Solid-Phase Fe(II)-Mediated Autotrophic Denitrification for Nitrate Removal from Wastewater with a Low Carbon-to-Nitrogen Ratio

AbstractIn this study, three solid-phase iron sources—FeS, FeCO3, and sponge iron—were used to investigate the autotrophic denitrification efficiency in low-carbon-to-nitrogen (C/N) wastewater. Amo...
