Biological nitrogen removal by the use of Sequencing Batch Reactors (SBR) is today an accepted and wellproven model. The Nowy Targ SBR plant has been in operation for 15 years, and comprehensive performancedata are available for assessment. This paper focuses on the 2005 year operation, characterised by high organicand nitrogen loading and also very high chromium loads. The available performance data allows an analysis ofboth nitrification rates and denitrification rates, along with an assessment of the temperature influence. Theresults reveal a high nitrification rate even at temperatures in the range 6–10°C, close to 2 g N/kg VSS/h, a clearrelation between nitrogen loading and nitrification as well as denitrification. Furthermore a relation betweenthe COD/N- ratio and the nitrification rate is found: the rate increases with decreasing COD/N-ratio.
