- •
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.
