These edits are not suitable as you've completed them. This article is about the metabolic process of denitrification, not denitrification in a sewage sludge plant. If you wish to create a separate article as such you've got my support, but this is not an appropriate massive edit. Halogenated ( talk) 03:08, 15 April 2008 (UTC) reply
