TL;DR: A consistent and descriptive nomenclature is suggested for reactors in which the anammox process is employed, and Reactors with a high specific surface area like the granular sludge reactor employed in Rotterdam provide the highest volumetric loading rates.

TL;DR: The start-up of the first full scale Anammox reactor is complete and the reactor shows stable operation, even at loading rates of 10 kg N/m3, which means the Anamm ox granular sludge technology has been proven on full scale.

TL;DR: Comparison of the inorganic nitrogen removal rate of the actual wastewater and that of control artificial wastewater showed that these two kinds of wastewater were very suitable for anammox treatment.

TL;DR: The successful granulation of the Anammox microorganisms led to a stable nitrogen removal performance and the maximum nitrogen removal rate of the lab-scale reactor was observed to be 2.9 kg/(m3 x d) after 173 days of operation and that of the pilot-scale reactors was 6.4 kg/( m3 xD) after 12 months of operation.

TL;DR: It is concluded that a granule-type airlift reactor with DO control is feasible for achieving stable nitritation in nitrite-type nitrification process with an aerobic granular biomass.
