Online nitrate measurement can be achieved using either a UV absorbance method or a colorimetric method. Which is the best available technology is dependent on the application.
Nitrate has a strong absorbance peak at low UV wavelengths and due to the low maintenance of operating a UV sensor and the wide dynamic range it offers, is often the preferred method.
In some applications, it may be preferable to combine chromatography with UV analysis in order to ensure separation of nitrate and nitrite prior to UV analysis.
Alternatively, for low levels of nitrate, a colorimetric method might be utilised.

Agricultural runoff can lead to groundwater contamination with nitrate. By monitoring nitrate levels at the source an early warning system can be utilised to protect drinking water sources.
Ensuring discharge compliance for COD, BOD and ammonia can lead to multiple instruments being required and maintained, increasing the complexity for operators.
Nitrate and nitrite are notoriously hard to quantify when in solution together. In Anammox wastewater treatment processes, however, being able to separately monitor nitrite from nitrate is crucial.
RAS are finely balanced ecosystems, requiring careful control of the water quality to maximise yields and avoid a catastrophic loss of stock. Utilising simple pH and dissolved oxygen(DO) control sometimes isn’t sufficient.
Monitoring of drinking water sources for contaminants requires an advanced event detection system based on UV-Vis spectroscopy and not just parameters. Pollution into groundwater can take many forms and by using event detection software, a flexible and intelligent system can provide the protection that is required.
