Respiratory denitrification experiments were performed using different carbon sources (acetic acid, glucose, methanol, molasses). In the culture media with glucose and molasses, COD consumption and denitrification rates were higher than with acetic acid and methanol. However, up to 30-40% of reduced nitrate and nitrite were converted to ammonium in glucose and molasses media. In the culture media with acetic acid and methanol, ammonium was not accumulated. Some of the consumed COD seemed to be used by the acid formers for the acidification in glucose and molasses media. By initial pH control of with molasses media, higher denitrification rate (up to 99%) and faster response could be obtained.
