Abstract
The primary focus of this research was an assessment of the external carbon source (RCS5, RCS15, and TPA5) as environmentally friendly, alternative of the carbon sources in the denitrification process. These alternative carbon sources (RCS5, RCS15, and TPA5) demonstrated the same grade of biodegradability and denitrification rate. The nitrogen removal efficiencies of RCS5, RCS15, and TPA5 in field application test were 77.4%, 58.7%, and 62.4%, respectively. The application of the alternative carbon sources (RCS5, RCS15, and TPA5) to sewage from K, N and S-STP facilities reduced the cost of an alternative carbon source more than 55.4% when compared with methanol application.
