Abstract

Studies were carried out to evaluate the performance of CANON process for the treatment of nitrogen containing digester effluent. The experimental studies were performed in a laboratory scale column type sequencing batch reactor. Anammox microorganisms were successfully enriched in the mixed culture. The microorganisms were acclimatised by systematically feeding the digester effluent. The maximum TKN, ammonium and COD removal of 90%, 98% and 91% respectively was achieved at maximum organic loading.
