In environmental engineering denitrification generally refers to an anaerobic biological process in which nitrates (NO3) are ultimately reduced to atmospheric nitrogen (N2). Denitrification may play an integral role in maintaining the integrity of the receiving waters of wastewater treatment plant, depending on the ecology of the receiving body. Processes that control anthropogenic nitrogen are divided into two categories:
This site is designed to give an introduction to not only the technology of denitrification, but also to why it is important in environmental planning. Although denitrification is a relatively new technology (the first wastewater plant capable of denitrification went on line in 1969 at South Lake Tahoe, California), the subject is vast and the nitrogen cycle is intricate. This web site is intended to be introductory, not comprehensive. Those seeking more detail are referred to the annotated bibliography that concludes this site. It is the hope of the author that development of this bibliography will be ongoing project to facilitate research on the topic.
