Comparison of different strategies for nitrogen removal by simultaneous nitrification and denitrification process in a batch rotating disk reactor
(Natural State Research, Inc., 2017-10)
In this paper, different strategies of aeration and organics feed in the reactor were studied toevaluate the simultaneous nitrification and denitrification (SND) process efficiency for a sequencing batchrotating disk biofilm ...
A novel aerobic-anoxic biological filter for nitrogen removal from UASB effluent using biogas compounds as electron donors for denitrification
(IMPRENTA UNIV ANTIOQUIA, 2011)
The performance of a new trickling filter (TF) configuration composed of an upper compartment for nitrification and a lower compartment for denitrification of effluent from a UASB reactor treating domestic sewage was ...
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 ...
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 ...
Predicting Accumulation of Intermediate Compounds in Nitrification and Autotrophic Denitrification Processes: A Chemical Approach.
Nitrification and sulfur-based autotrophic denitrification processes can be used to remove ammonia from wastewater in an economical way. However, under certain operational conditions, these processes accumulate intermediate ...
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. ...
Feasibility of a Sequencing Reactor Operated in Batch and Fed-batch Mode Applied to Nitrification and Denitrification Processes
(ASOC QUIMICOS, 2009)
The objective of this work was to study the operational feasibility of nitrification and denitrification processes in a mechanically stirred sequencing batch reactor (SBR) operated in batch and fed-batch mode. The reactor ...
Parâmetros operacionais na remoção biológica de nitrogênio de águas por nitrificação e desnitrificação simultâneaOperating parameters on biological nitrogen removal of water by simultaneous nitrification and denitrification
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2016-01)
O nitrogênio é um dos contaminantes mais importantes presentes nas águas residuais. As alternativas tecnológicas mais usuais para o tratamento de águas contendo esse composto lançam mão do ciclo bioquímico do nitrogênio, ...
