Act early and improve process control by accurately detecting events

With the UNUM IoT sensor, you can reliably measure up to six parameters directly and additionally monitor virtual parameters.

With LED light sources including state-of-the-art UVC LEDs, the UNUM offers superior performance and stability compared to Xenon or mercury lamp-based sensors.

Through 4G communications, raw measurement data is securely uploaded to the AQUA-INSIGHT cloud for AI analysis.

Innovative sensors from AQUALITAS utilize proprietary and patent-pending AI technology for superior measurement and stability. By monitoring sensors' health and compensating for measurement errors, AQUA-INSIGHT AI ensures the sensors are functioning at their best. By providing alerts when simple maintenance is needed, Aqua-INSIGHT saves technicians time and prevents them from having to service the units daily.

Precise and stable monitoring of optical parameters

An example of the optical measurements taken over a month in an on-site secondary wastewater treatment installation. Turbidity is represented by a grey line with values on the right. Dark turquoise line denotes TOC and light turquoise line represents Nitrate, both with values on the left. Lab-tested grab samples are indicated by red circles.

Site-specific TOC and Nitrate calibration with single-sample

The measurement of TOC is carried out using potassium hydrogen phthalate (KHP) calibration standards. As TOC is site-specific with seasonal variation, standard calibration can result in an increased error. A site-specific TOC and nitrate calibration technique based on a single validated laboratory test has been developed and validated by AQUALITAS .

Measurements taken at different stages of wastewater treatment are shown in the plot. The open circles represent the calculated TOC based on standard KHP calibration. The full circles represent single-sample site-specific calibration.
