Simultaneous partial Nitritation, Anammox and Denitrification (SNAD) process for treating ammonium-rich wastewaters
… during the last years. Since the discovery of anammox bacteria the traditional theory of biological nitrogen removal has been extended to new nitrogen metabolic pathways. This thesis deals with the study of Simultaneous partial Nitritation, Anammox and Denitrification (SNAD) process in a …

Pilot Scale Application of Partial Nitritation Anammox and Partial Denitrification Anammox Treating Industrial Fertilizer Waste with High Ammonia and Nitrate
… approach using anaerobic ammonium oxidizing (anammox) bacteria in two shortcut nitrogen removal methods that are more cost effective than conventional nitrification-denitrification. The first method, partial nitritation anammox (PNA) is very effective at removing high strength NH4 from …

The Economic and Technical Feasibility of the Application of Partial Nitritation Anammox Technology Over Conventional Nitrification Denitrification for the Treatment of Sidestream Liquor at Cape Flats WWTP
… (MLE) configuration) with a novel partial nitritation/ anammox (PN/A) process. The sidestream liquor was characterised by mass balance over the AD process. Steady-state models were used to predict equipment sizes and determine the process efficiency for each treatment technology. …

Mechanistic Understanding of the NOB Suppression by Free Ammonia Inhibition in Continuous Flow Aerobic Granulation Bioreactors
A partial nitritation-anammox continuous flow reactor (CFR) was operated for eight months demonstrating that a mixture of large anammox-supported aerobic granules (ASAGs) and small conventional aerobic granules (CAGs) can be maintained stably for extended periods of time. The influent NH4+ was kept …

EXPLORING INNOVATIVE TECHNOLOGIES FOR NUTRIENT REMOVAL AND RECOVERY FROM AGRO-INDUSTRIAL WASTEWATER: ANAMMOX AND ELECTROCHEMICAL PROCESSES
… effluent). Particularly, the single-step Partial Nitritation/Anammox (PN/A) and the electrochemical mediated precipitation processes were explored with the aim of nutrient recovery.

Assessment of a Fixed Media Partial Denitrification/Anammox Process Startup in a Full-Scale Treatment Train
Partial denitrification anammox (PdNA) is an emerging wastewater treatment technology with the potential to increase process capacity and save on energy and carbon. PdNA circumvents potential issues with stability of the more familiar mainstream partial nitritation anammox (PNA) process. The PdNA …

Intensification of Biological Nutrient Removal Processes
… removal processes; including nitrite shunt, partial nitritation/anammox, and partial denitrification/anammox, as well as low-carbon biological phosphorus removal, were critically-evaluated in this study with an overall objective of intensification of existing infrastructure. At the beginning …

Zeolite Incorporated Materials for Targeted Biomass Retention and Pollutant Removal
… biofilm carriers were designed to facilitate the partial nitritation-anammox (PNA) processes in mainstream wastewater, where significant cost savings and improved treatment could be realized. Zeolite particles and zeolite coated membranes in batch systems fed with mainstream-like synthetic …
