Correlation between nitrous oxide (N 2 O) emission and carbon to nitrogen (COD/N) ratio in denitrification process: a mitigation strategy to decrease greenhouse gas emission and cost of operation

The reliability and accuracy of in-situ ion selective electrode and ultraviolet (NO ) probes have been investigated at four different treatment plants with different operational conditions. This study shows that the mentioned probes tend to compromise their accuracy and trending stability at lower N...
