Highlights

•

Anammox process were established in pilot- and full-scale IFAS reactor.

•

AOB lie in t flocculent sludge and anammox bacteria is attached to the biofilm.

•

NOB was washed out from the IFAS reactor and no attached growth was observed.

•

Segregation of biomass allows high nitrogen removal and a flexible operation.
