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

ALEXANDRIA, Va.  – Biological denitrification—the removal of nitrate and nitrite from treated wastewaters—is becoming more common for both nutrient removal as well as the need to protect potable groundwater from high concentrations of these compounds. This process requires a carbon source, which is most often provided from the influent carbon, but in many cases must be augmented with an external source. Although methanol is most commonly used, an article appearing in the June 2013 issue of Water Environment Research (WER), describes the use of gasoline-denatured ethanol as an alternative compound.

Formerly available to subscribers only, selected WER articles such as this one are available at no-cost to the public on a monthly basis through a special open-access program. According to WER Editor-in-Chief Michael Stenstrom, the authors of this month’s 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.”

Published since 1928 by the Water Environment Federation, WER features peer-reviewed research papers and research notes, as well as state-of-the-art and critical reviews on original, fundamental, and applied research in all scientific and technical areas related to water quality, pollution control, and management. Originally known as the Sewage Works Journal, WER is available in both print and online formats and receives approximately 300 new research submissions each year.
