WASTEWATER


Problem
Nitrous oxide has a large effect on the climate. Such an effect is 298 times greater than CO2. It is therefore extremely important that we reduce the emission of NO2 and thus the greenhouse gas emission – if we are to achieve the set climate targets.

Nitrification in the waterworks process tanks is believed by some to be a source of the development of nitrous oxide, which is why by measuring nitrite you can also gain insight into the processes and better control them.

Solution
Just-measure has a solution that can measure both nitrite and nitrate simultaneously in wastewater process tanks as well as in bypass after filtering.

Result, customer quote
“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 changes in our management style, which should result in less nitrous oxide production.”
