The AquaSentinel WaterSecurity Sensor detects algal bloom, toxins and pollutants in real-time and online. It monitors and measures the health of algae that occur naturally in all surface waters.
Monitoring the health of Algae
The AQS monitors the photosynthetic processes of the algae using light at specific wavelengths in order to see how those processes deviate from normal healthy algae.
Every minute or less, a fresh sample of algae is automatically loaded into the device and stress-tested with intense light which is then digested by the algae while the AquaSentinel observes this process.
Specific toxins present in the water affect photosynthesis in specific ways and at specific points along the chemical pathway, and this results in specific characteristic curves which serve as fingerprints for those toxins. Each curve is compared against an online database of normal and toxic fingerprints and matched to the closest one.
A non-match to the expected normal curve triggers an alarm that an unknown substance is present in the water and affecting the algae. A close match to a stored toxin fingerprint triggers an alarm identifying the substance that is present in the water. In both cases, the AquaSentinel automatically discharges the tested water sample into a clean sample container so that it can be further tested in a laboratory.
