Dissolved
nitrogen in wastewater treatment plant (WWTPs) effluent includes inorganic
(ammonia, nitrite and nitrate nitrogen) and organic forms. Dissolved organic
nitrogen (DON) becomes an important portion of WWTP effluents, because of high
inorganic nitrogen removal is able to achieve in these plants. Biodegradable dissolved
organic nitrogen (BDON) is a portion of DON that
can be mineralized by an acclaimed mixed bacterial culture. In this study, the
fate of DON and BDON in effluent of wastewater treatment plant including
4-stage Bardenpho process was investigated. DON values were determined between
4.1-19.7 mg/L in effluent. The biodegradability of WWTP effluent samples were
determined by using a mixed bacteria culture and identified between 41%-98% for
different sampling time. BDON/total dissolved nitrogen ratio was found in
7%-81% ranges.
