Deammonification (i.e. combined partial nitritation and anaerobic ammonia oxidation) is known as an efficient and resource saving sidestream process option to remove high strength nitrogen load from sludge dewatering liquors. The process uses less energy, 1.2 kWh/kg N removed versus 5-6kWh/kg N removed for conventional nitrification/denitrification in the mainstream and requires no carbon dosage. The paper describes a cyclone-device as a significant feature of the DEMONprocess for additional enrichment of anammox biomass in the system. Model results supported by activity measurements indicate almost doubling of the anammox- to aerobic AOB mass ratio improving the robustness against disturbances. Ongoing full-scale experiments explore the potentials for anammox retention in the main liquid train by cyclone operation
