The Anammox® process removes nitrogen from wastewater in a cost effective way. Anammox® offers great advantages compared to conventional   3 Jun 2019 Executive Summary. Anammox stands for Anaerobic Ammonium Oxidation. The process was discovered in the early nineties and has great  The anammox process is highly efficient (90% nitrogen removal) and economi- cal, since it requires 60% less oxygen than the tradition method, produces less  3 Jan 2021 Anammox, an abbreviation for ANaerobic AMMonium OXidation, is a globally significant microbial process of the nitrogen cycle.

The results showed that oxygen is a major controling factor The tremendous input of ammonium and rare earth element (REE) ions released by the enormous consumption of (NH4)2SO4 in in situ leaching for ion-adsorption RE mining caused serious ground and surface water contamination. Anaerobic ammonium oxidation (anammox) was a sustainable in situ technology that can reduce this nitrogen pollution. In this research, in situ, semi in situ, and ex situ 2. Materials and methods 2.1. Description of the acetate-fed Anammox process A 1.5 L laboratory-scale sequencing batch reactor (SBR) with 50% exchange volume was established and operated under low nitrogen loads, given that the influent ammonium ((NH4)2SO4) and nitrite (NaNO2) were batch-feed at approximately 50 mg N/L, respectively. The correlation analysis indicated that the horizontal transfer of antibiotic resistance genes and copA triggered by intI1 facilitated the generation of multiresistance in the anammox process.

In this work, a model framework integrating DAMO and anammox process was constructed based on suspended-growth systems. The proposed model was calibrated and validated using experimental data from a 2019-05-06 · The anammox process is an economically favourable nitrogen removal process; however, low growth rates of anammox biomass block its more widespread application. As different approaches on techniques for anammox bacteria growth acceleration were tested, this study focused on long-term evaluation of hydrazine addition in the start-up phase.

The step to introduce anammox in the mainstream is de-creasing, but lab- and pilot-scale studies on real municipal wastewater are yet lacking. However, several pilot As Anammox bacteria favour anaerobic condi-tions, the Anammox process is reversibly inhibi-ted by the dissolved oxygen (DO) concentration.

However, the effect of AgNPs on anaerobic ammonium-oxidizing (anammox) granules remains unknown. Here we present the underlying promotion mechanism of AgNPs on anammox granules from a In this study, a laboratory-scale anammox process in a membrane bioreactor (AnMBR) was used to startup the anaerobic ammonium oxidation (anammox) process from conventional activated sludge. Stable operation was achieved after 125 days. From that time, nitrogen load was gradually increased.
