Together with a Danish wastewater plant we will start measure nitrite and nitrate from process tank through a filtered bypass string.
This to get data from the nitrification, to be able to better control the processes and in that way lower the development of NO2 (which is x298 worse than CO2).
‘We have a presumption that it is during nitrification that nitrous oxide is developed, due to incomplete nitrification, i.e. after the formation of nitrite.
By measuring nitrite, we will hopefully be able to clarify whether incomplete nitrification is the cause of nitrous oxide production.
This knowledge can be used to make some changes in our management style, which should hopefully result in less nitrous oxide production.’
