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 ...
Resilience of nitrification process in agricultural and restored soils of central Argentina
(Global Institute for Research & Education, 2013-07)
The aim of this study was to assess the resilience degree of soil nitrification process (by nitrate content, nitrification rate, and nitrifier abundance measurements), in soils of central Argentina. Soil nitrification ...
Ammonia volatilization losses from surface-applied urea with urease and nitrification inhibitors
(2012-09-01)
Urease inhibitor (UI) and nitrification inhibitor (NI) have the potential to improve N-use efficiency of applied urea and minimize N losses via gaseous emissions of ammonia (NH 3) to the atmosphere and nitrate (NO3-) ...
Ammonia volatilization losses from surface-applied urea with urease and nitrification inhibitors
(2012-09-01)
Urease inhibitor (UI) and nitrification inhibitor (NI) have the potential to improve N-use efficiency of applied urea and minimize N losses via gaseous emissions of ammonia (NH 3) to the atmosphere and nitrate (NO3-) ...
Nitrification inhibition in tropical soil under no tillage system
(2014)
In no-tillage systems (NTS), biological activity and nitrification process in the soil are higher due to higher organic matter and moisture contents, resulting in higher levels of nitrate compared with areas under conventional ...
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 ...
Respirometric techniques for assessment of biological kinetics in constructed wetland
(I W A Publishing, 2007-01-01)
The aim of this research was the development of a procedure to measure biological kinetics of organic matter oxidation and nitrification in constructed wetland, by using respirometric techniques. Columns simulating cores ...
Detection and Quantification of Nitrifying Bacteria Using Real-Time PCR
(2020-01-01)
Nitrification is the microbial-mediated transformation of ammonium (NH4 +) into nitrate (NO3 −). Many plant species depend on the availability of NO3 − as the main source of nitrogen (N). On the other hand, because NO3 − ...
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 ...
