Application of a moving-bed biofilm reactor for sulfur-oxidizing autotrophic denitrification
Sulfur-oxidizing autotrophic denitrification (SO-AD) was investigated in a laboratory-scale moving-bed biofilm reactor (MBBR) at a sewage temperature of 22 °C. A synthetic wastewater with nitrate, sulfide and thiosulfate was fed into the MBBR. After 20 days' acclimation, the reduced sulfur compounds were completely oxidized and nitrogen removal efficiency achieved up to 82%. The operation ...

Top Applications of Shortcut Nitrogen Removal
Skipping a step streamlines treatment of a range of high-ammonia wastewater sidestreams Over the years there has been an ongoing quest to make wastewater nutrient removal more efficient than traditional activated sludge treatment, which is effective but uses a great deal of energy, carbon, and oxygen. There has been progress, starting with full nitrification-denitrification and simultaneous ...

N2O emissions from a one stage partial nitrification/anammox process in moving bed biofilm reactors
Nitrous oxide (N2O) emissions from wastewater treatment are getting increased attention because their global warming potential is around 300 times that of carbon dioxide. The aim of the study was to measure nitrous oxide emissions from one stage partial nitrification/anammox (Anaerobic Ammonium Oxidation) reactors, where nitrogen is removed in a biological way. The first part of the ...

Anammox bacteria enrichment and characterization from municipal activated sludge
A sustainable option for nitrogen removal is the anaerobic ammonium-oxidizing (anammox) process in which ammonium is oxidized to nitrogen gas with nitrite as electron acceptor. Application of this process, however, is limited by the availability of anammox biomass. In this study, two Brocadia-like anammox phylotypes were successfully enriched, detected and identified from an activated sludge ...
