The results of laboratory scale modelling and real scale performance of the pre- and post-denitrification of a wastewater from the production of industrial fertilizers, pesticides and rubber additives are presented. As a substrate for the pre-denitrification, the biologically degradable organic compounds present in the influent were used. Selected wastewaters from chemical industry were used as a substrate for the post-denitrification. The results of the laboratory scale research of the pre-denitrification were successfully verified in real scale, an efficiency of 97% and 88% was reached for the removal of NO2––N and NO3––N respectively. The efficiency of the post-denitrification in real scale was 15% from the entering amount of NOx––N (NO2––NO3––N). Pre-denitrification removed about 190 kg NOx––N and post-denitrification about 85 kg NOx––N daily.
