A Rain Garden for Nitrogen Removal from Storm Runoff in Tropical Cities
(Universidad Nacional, 2019)
Nitrogen supply associated with rhizobacteria in the first productive cycle of Marandu grass
(2021-01-01)
The rhizobacteria of genus Azospirillum and Bacillus are effective at fixing atmospheric nitrogen, promote plant growth and can largely contribute to beneficial recovery from degraded pastures. This study aimed to evaluate ...
Removal of nitrogen and phosphorus from domestic wastewater by electrocoagulation: Application of multilevel factorial design
(Polish Society of Ecological EngineeringPL, 2020)
The main objective of this investigation was to evaluate the efficiency of electrocoagulation for the elimination of nitrogen and phosphorous from domestic wastewater and to determine the main operating parameters affecting ...
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, ...
Removal of nitrogen and organic matter in an intermittently aerated horizontal subsurface flow constructed wetland
(2020-01-01)
The objective of this work was to evaluate the effect of intermittent aeration on the removal of ammonium (NH4+), total nitrogen (TN) and chemical oxygen demand (COD) in a horizontal subsurface flow constructed wetland ...
Effect of hydraulic retention time on chemical oxygen demand and total nitrogen removal in intermittently aerated constructed wetlandsRemoção de DQO e Nitrogênio Total em alagados construídos com aeração intermitente em relação ao tempo de detenção hidráulica
(2020-01-01)
This study evaluated the effect of hydraulic retention time on chemical oxygen demand (COD) and total nitrogen (TN) removal in an intermittently aerated constructed wetlands. Two horizontal subsurface-flow constructed ...
Effect of ammonia load on efficiency of nitrogen removal in an SBBR with liquid-phase circulation
(Brazilian Society of Chemical Engineering, 2008)
The removal of biological nitrogen from a synthetic wastewater with different ammonium nitrogen concentrations (50 and 100 mgN-NH4+/L) by a nitrification and denitrification process using a sequencing batch biofilm reactor ...
Photo-Fenton approach for the determination of organic nitrogen in rainwater
(2018-10-01)
The importance of taking the organic forms of nitrogen (ON) into account when estimating atmospheric nitrogen deposition has been known for a long time. However, there is still only a modest amount of data on organic ...
Anoxic Microbial Community Robustness Under Variation of Hydraulic Retention Time and Availability of Endogenous Electron Donors
(Springer, 2020-05-11)
The ADNMED (Anaerobic Digestion, Nitrification, and Mixotrophic Endogenous Denitrification) system comprises a triple chamber configuration that was shown to provide high-quality effluent regarding carbon, nitrogen, and ...
