Nitrogen Removal from Milking Center Wastewater via Simultaneous Nitrification and Denitrification Using a Biofilm Filtration Reactor
Nitrogen Loading Rate Simultaneous Nitrification and Denitrification
2016/5/18
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which should be separately managed from livestock manure due to the negative impacts of manure nutrients a...
Measuring and modelling seasonal variation of gross nitrification rates in response to long-term fertilisation
seasonal variation gross nitrification rates long-term fertilisation
2010/1/21
The formation of nitrate (nitrification) in soils is an important process that influences N availability for plant uptake and potential N losses as well. Gross nitrification is an effective measure by...

Assimilatory uptake rather than nitrification and denitrification determines nitrogen removal patterns in streams of varying land use
Assimilatory uptake nitrification denitrification deter nitrogen removal patterns in streams of varying land use
2014/4/18
Agricultural and urban land use increase nitrogen (N) concentrations in streams, which can saturate biotic demand by plants, algae, and bacteria via assimilative uptake, and by nitrification and denit...
