Diversity of nitrifying bacteria in a full-scale petroleum refinery wastewater treatment plant experiencing unstable nitrification
(Elsevier Science, 2010-09)
We have investigated bacterial populations relevant to nitrification in a full-scale activated sludge plant receiving wastewater from a petroleum refinery showing unstable nitrification. Inhibition of ammonia oxidation was ...
Simultaneous heterotrophic nitrification and aerobic denitrification of wastewater in granular reactor: Microbial composition by next generation sequencing analysis
(Elsevier Ltd, 2020-08)
Dairy effluents contain limited nitrogen for biological treatment. In the present study a cheese whey wastewaterwas supplemented with ammonia to obtain suitable COD:N ratios. The effects of the organic load and micronutrientson ...
The use of a flocculant additive and its effect on biofloc formation, nitrification, and zootechnical performance during the culture of Pacific white shrimp Penaeus vannamei (Boone, 1931) in a BFT system

Performance of anoxic -oxic sequencing batch reactor for nitrification and aerobic denitrification
(IntechOpen, 2019)
The biological nitrogen removal (BNR) involves two processes: nitrification and denitrification. Denitrification occurs almost exclusively under facultative anaerobic or microaerophilic conditions; however, aerobic ...
Nitrification and aerobic denitrification in anoxic-aerobic sequencing batch reactor
(Elsevier, 2016-01)
The aim of this study was to evaluate the feasibility of achieving nitrogen (N) removal using a lab-scale sequencing batch reactor (SBR) exposed to anoxic/aerobic (AN/OX) phases, focusing to achieve aerobic denitrification. ...
Application of a fenton process after a biological nitrification treatment : a successful case for leachate treatment
(Elsevier, 2022-04-09)
Leachate is one of the most complex wastewater due to the variable composition depending on landfill age, time, climate, waste composition, etc. Usually, conventional treatments are not enough to satisfy the environmental ...
