Next-Generation Low-Cost Nitrate Sensor

Aquamonitrix from TelLab is a portable, deployable sensor for remote near-continuous water monitoring for nitrate and nitrite.

It has been developed to set a new standard in cost-effective nutrient analysis in a wide range of applications. In particular, it can help water resource managers identify and address problems such as excess nitrogen loading to waterways, which can lead to eutrophication, hypoxia and toxic algal blooms. Moreover, in Europe it offers an integrated solution to meet the requirements for frequent water quality monitoring under the Water Framework Directive (WFD).

Designed around the US EPA Nitrogen and Nutrient challenge specifications, it is the only sensor currently qualified for ongoing 6-month testing under the US EPA’s Advanced Septic System Nitrogen Sensor Challenge.

Some 21 Aquamonitrix prototypes are also currently being tested in 11 operational environments around Europe as part of the Ecosens Aquamonitrix project, funded through the EU LIFE programme.

Advanced prototypes are currently available for evaluation and project work. We expect the first commercial products to be available within the next 12 months.

Setting a new standard in cost-effective nutrient analysis

  • Enhanced performance in terms of precision and accuracy, adaptable to different applications in the water sector

  • Reduced power and chemical consumption, compared to conventional methods

  • Remote, near-continuous monitoring, allowing pollution issues to be detected as soon as they occur

  • Low cost compared with current systems

  • Versatile IoT platform that will allow deployment of scalable and flexible solutions for connected products

  • Increased robustness in terms of operational and information reliability

Key benefits

The innovative technology, available at a competitive cost, will allow for increased frequency of water quality monitoring, with remote access to the device and results.

The device can carry out a near-continuous analysis of water sources, monitoring major indicators of water quality, including nutrients nitrate and nitrite, with ongoing work in the detection of phosphate, pH (through colorimetry) as well as COD/TOC, Total N, suspended solids through reagentless detection.

This affordable solution will result in increased monitoring data, making it easier for management decisions and compliance with regulations. Moreover, its efficient power consumption will allow longer deployment periods and reduced maintenance needs.
