Abstract: Anaerobic ammonium oxidation (Anammox) is an efficient biological route to nitrogen removal under anoxic conditions. The high sensitivity to environmental conditions, slow growth, and low sludge production for reactor start-up are some drawbacks to the full-scale application of this technology. Thus, preservation and successful reactivation of Anammox sludge could be one of the solutions. Anammox granule preservation (low temperature (4 °C) and freezing (− 4 °C) with KNO3) standouts as a practice for fast reactor start-up and improvement of its performance. However, the integrity of granules and bacteria activity must also be maintained during the preservation period to provide a fast reactor start-up. In the present study, the preservation was evaluated at 4 and − 4 °C as sustainable techniques for granular Anammox sludge storage. Subsequently, the reactivation of both Anammox sludge in up-flow bed reactors and the integrity of the freezing granules (preserved under − 4 °C) were analyzed by extracellular polymeric substances (EPS). Anammox can be successfully stored at 4 °C, for up to 3 months. It is also possible to recover the sludge in a short time (21 days), with a nitrogen removal efficiency higher than 80%. Under freezing conditions after 11 months (− 4 °C), the sludge can be recovered after 45 days, reaching around 80% nitrogen removal efficiency even with the granule’s low integrity. Based on these results, refrigeration and freezing can be used as cost-effective and feasible techniques for Anammox sludge preservation and reactivation. This is important for biomass transport and reactor start-up, accelerating its practical use for wastewater treatment plants.
