The significance of slowly biodegradable COD on denitrification in the OAO process.

The capacity of particulate organic matter to act as a carbon source for denitrification is a significant concern in wastewater treatment facilities. The biodegradability of particulate matter is essential to its applicability. This research aims to ascertain the role of particulate organic matter in denitrification by classifying COD, conducting pre and post denitrification tests, and analyzing the oxygen utilization rate (OUR) profile of respiration.
