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 ...
An upflow fixed-bed anaerobic-aerobic reactor for removal of organic matter and nitrogen from L-lysine plant wastewater
(NATL RESEARCH COUNCIL CANADA-N R C RESEARCH PRESS, 2009)
This paper reports on the design of a new reactor configuration - an upflow fixed-bed combined anaerobic-aerobic reactor - can operate as a single treatment unit for the removal of nitrogen (approximate to 150 mg N/L) and ...
Modified coupling agents based on thiourea, immobilized onto silica. Thermodynamics of copper adsorption
(Elsevier Science BvAmsterdamHolanda, 2009)
Nutrient uptake and removal by sweet potato fertilized with green manure and nitrogen on sandy soil
(Sociedade Brasileira de Ciência do Solo, 2022)
Nitrogen dynamic in vitro using sludge of a sewage stabilization pond from Patagonia (Argentina)
(Springer Heidelberg, 2021-02)
A relevant and current aspect of wastewater treatment systems is related to the processes of the nitrogen cycle that results in its elimination in gaseous forms. In the present study, we report the first measurements of ...
Conventional and new concepts of biological treatment processes for the nitrogen removal from wastewater
(Universidade Tecnológica Federal do Paraná (UTFPR), 2012)
Effect of intermittent induced aeration on nitrogen removal and denitrifying-bacterial community structure in Cork and gravel vertical flow pilot-scale treatment wetlands
(Taylor & Francis, 2021)
Abstract: In this work, we have evaluated the impact of intermittent induced aeration in total nitrogen (TN),
ammonia (NH4-N) and nitrate-nitrogen (NO3-N) removal in four pilot-scale vertical flow constructed
wetlands ...
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 ...
GASES DE NITROGÊNIO REATIVO COMO PRECURSORES DO AEROSSOL ATMOSFÉRICO: REAÇÕES DE FORMAÇÃO, PROCESSOS DE CRESCIMENTO E IMPLICAÇÕES AMBIENTAIS
(Sociedade Brasileira de Química, 2021-06-21)
The increased emissions of reactive nitrogen gases from anthropogenic sources to the atmosphere has been pointed out as responsible for triggering a series of environmental problems at the local, regional, and global scale. ...
