A novel aerobic-anoxic biological filter for nitrogen removal from UASB effluent using biogas compounds as electron donors for denitrification

Revista Facultad de Ingeniería Universidad de Antioquia, 2012
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 evaluated.

Diverse crop rotations offset yield-scaled nitrogen losses via denitrification

Communications Earth & Environment
Denitrification, a major source of gaseous nitrogen emissions from agricultural soils, is influenced by management. Practices promoting belowground diversity are suggested to support sustainable agriculture, but how they modulate nitrogen losses via ...

Carbon availability mediates differences in rhizosphere denitrification potential between intercropped plants

Frontiers in Sustainable Food Systems
Denitrification is an important loss pathway for nitrogen (N) in agricultural systems; however, it is at times unpredictable. Some of the uncertainty surrounding denitrification rates is due to soil heterogeneity and spatial variability, especially with ...

Factors Controlling Sediment Denitrification Rates in Grassland and Forest Streams

Terrestrial, Atmospheric and Oceanic Sciences, 2014
Sediment denitrification is an important nitrate (NO3-) removal process from agricultural streams. The direct and indirect factors that control denitrification rates in tributary sediments can vary depending on the types of agricultural activities and ...

Removal of Aluminum Nitride from Secondary Aluminum Ash and its Aluminum Recovery

Kuangchan zonghe liyong
The aluminum nitride in the secondary aluminum (Al) dross release ammonia gas when it contacts with water. Therefore, the aluminum nitride poses a serious security threat to the environment. Denitrification is an important way to realize the harmless and

Patterns and drivers of soil denitrification and its responses to nitrogen addition in steppe ecosystems

Environmental and Biogeochemical Processes
Soil denitrification, a pivotal microbial process responsible for ecosystem nitrogen loss and the emission of the greenhouse gas nitrous oxide (N2O), is intricately influenced by climate conditions and inherent soil properties.

Ocean acidification offsets the effect of warming on sediment denitrification and associated nitrous oxide production

Communications Earth & Environment
Rates of denitrification and associated nitrous oxide (N2O) production are expected to increase with global warming, leading to positive climate feedback. However, previous studies have not considered the combined effect of ocean acidification (OA, pCO2 ~
