Nutrients Measuring Device
Highly sensitive sensors measure nitrogen and phosphorous in water.
Easy-to-use and integrate with other devices
Monitoring the discharge of nutrients into aquatic environments is becoming more important as an increasing number of activities impact watercourses.
Wastewater from households and industry can result in nutrients such as nitrogen and phosphorus being discharged into bodies of water. Equally, loss of nutrients from agriculture and fish farming have repercussions, too.
This nutrient overloading of seas, coastal waters, lakes, rivers and groundwaters can result in a series of adverse effects known as eutrophication. This richness of nutrients causes an imbalance of the chemical and ecological condition of aquatic ecosystems. Possible consequences include the deoxygenation of the water, production of toxins by certain algae, fish mortality, clogging and obstruction of irrigation channels, effects on recreational uses and more.
ADASA has extensive experience in designing and developing continuous monitoring systems that allow forewarning of nutrient levels. The technologies and the data they provide unearth valuable information on daily, seasonal and eventual changes in water quality conditions. Results can give strong indications on the overall health of the water body.
In collaboration with universities and research groups, we have actively participated in the design and development of digestion procedures and water samples pre-treatments. We also worked on a series of highly sensitive miniaturized ISE (ion selective electrode) potentiometric sensors, which measure the main forms of N and P:
- Total ammonium-nitrogen (TAN).
- Total phosphorus (TP).
These sensors are easily integrated into flow injection and analysis (FIA) systems and allow the detection of low concentrations of nutrients in low turbidity waters. They are particularly useful for natural waters classified as especially sensitive and vulnerable, and process waters used for aquaculture.
For water with high levels of turbidity, we use ISE potentiometric sensors in probe format, with a hydraulic circuit resistant to clogging, to measure of the total ammonium-nitrogen (TAN). The potentiometric sensors provide a greater range of measurement, up to 100ppm, which makes them ideal for process controls in industry and agriculture.Show less
