The performance stability and its recovery mechanisms of a partial nitritation-anammox process were investigated. A one-stage airlift enhanced micro-granules (AEM) system was operated for 650 days continuously to treat 50 mg-NH4/L wastewater. During the stable stage, high nitrogen removal efficiency 72.7 ± 8.4% lasting 230 successfully achieved under 0.28 L/min aeration rate 0.10–0.20 mg/L diss...
Simultaneous ammonium–nitrogen (NH₄⁺–N) removal and orthophosphate–phosphorus (PO₄–P) biomineralization was studied in two granular sludge sequencing batch reactors treating urban sidestream centrate through the one-stage partial nitritation–anaerobic ammonium oxidation (anammox) process. By adding an external source of calcium, concomitant conversion rates up to 0.32 g NH₄⁺–N/(L·days) 12 mg PO...
The implementation of autotrophic anaerobic ammonium oxidation processes for the removal of nitrogen from municipal wastewater (known as "mainstream anammox") bears the potential to bring wastewater treatment plants close to energy autarky. The aim of the present work was to assess the long-term stability of partial nitritation/anammox (PN/A) processes operating at low temperatures and their re...
