Abstract: The autotrophic nitrogen removal process (partial nitritation combined with the Anammox process) is a sustainable nitrogen
removal technique for nitrogen-rich streams. A modelling and experimental study was performed to define optimal process
conditions for the autotrophic nitrogen removal process. Special attention was given to the influence of feeding characteristics
on the performance of both the partial nitritation reactor and the Anammox reactor. It was revealed that the feeding
regime is an important factor in the successful start-up of the Anammox process. Nitrite concentration peaks at the beginning
of a feeding period will lead to an unsuccessful start-up, while a slow input of nitrogen speeds up the process. Feeding
regimes are less important in partial nitritation reactors since laboratory results show that slow or fast supply of influent
does not influence the growth of ammonium oxidisers
