WEF Research Examines Gasoline-Denatured Ethanol as an Alternative Carbon Source for Biological Denitrification

WEFThe Water Environment Federation (WEF) has published a white paper about biological denitrification - the removal of nitrate and nitrite from treated wastewaters. The process is becoming more common in facilities that are required to achieve high levels of nutrient removal. The process requires a carbon source, which is most often available in the wastewater influent, but in many cases must be augmented with an external carbon source that has a very low nitrogen and phosphorus content for enhanced treatment.

Although methanol is most commonly used, the article published in WEF's Water Environment Research (WER) publication describes the use of gasoline-denatured ethanol as an alternative compound. Michael Stenstrom, WER Editor-in-Chief, says the authors of the article “demonstrate the effectiveness of gasoline-denatured ethanol in a laboratory-scale investigation, and note its advantages as an alternative to methanol. This research provides a cost-effective and sustainable alternative for wastewater treatment plant managers.”
