  2. Evaluation of gasoline-denatured ethanol as a carbon source for wastewater denitrification

    Kazasi, AnnaVirginia Tech2011

    Methanol (MeOH) is a common external carbon source for wastewater denitrification, because of its low cost and low sludge yield. Ethanol (EtOH), on the other hand, is more expensive, but yields higher denitrification rates. This study introduces gasoline-denatured ethanol (dEtOH), which is now …
