Optiqua EventLab: real time water quality monitoring

24/7 information on water quality

The production of drinking water is performed with the greatest care, and this process is monitored in various ways. Traditional water quality monitoring solutions such as pH, EC and ORP monitor the treatment processes and grab samples are taken to the laboratory for analysis of a small set of parameters. This methodology, although common practice, is not designed to detect contaminations and leave water networks exposed to the risks of serious contaminations and major impacts on public health. Furthermore, quality monitoring in the distribution network is extremely limited, and as a result the quality of the water at the consumers tap is essentially unknown. The result: contamination events in the drinking water occur and are not picked up by the routine water quality monitoring procedures in place.

The Optiqua EventLab system is specifically designed to detect any type of chemical contamination of your water at the earliest stage. EventLab is a robust and sensitive solution for real-time continuous monitoring of water quality, that strongly outperforms these traditional sensor technologies (independent research shows by a factor 6), and that is validated and used by utilities all over the world. Easy installation, minimum maintenance and wireless data communication as well as SCADA connections facilitate the deployment at treatment plants (process and end quality control), in water distribution networks, in bulk water supply exit / entry point control applications, or for water intake protection (surface water).

EventLab is the solution of choice for applications where real time, continuous monitoring of the overall stability of the water quality is crucial. Common online sensors focus were developed to monitor process parameters, and are insensitive to many types of chemicals that can contaminate the water. Using such sensor for event monitoring gives a false sense of security. EventLab is specifically designed to detect any type of chemical contamination in the water at the earliest stage and strongly outperforms traditional sensor technologies in the detection of contaminations. EventLab is ideally suited for a wide range of applications, such as monitoring process stability at the treatment plant, monitoring for cross-connections, or as early warning system for integrity and security in the distribution network, e.g. detection of accidental back-flow events as well as intentional contaminations.

Complete solution, easy to install, low in maintenance

The EventLab system provides a complete solution including the sensor hardware, data transmission infrastructure and the software for data analysis and event detection.
The sensors are easy to install and are low in maintenance (no calibration, no reagents). Measurement data is transmitted from the monitoring stations to a central data server through cellular networks (2G, 3G), or alternatively can be transferred through SCADA.

In networked applications, such as drinking water distribution networks, EventLab can be deployed as a network of sensors, with distributed sensor nodes connected to a central server for data collection and processing. Data analysis and event detection is performed in real time by Optiqua’s proprietary algorithms in the central data collection and analysis software (EventLab Online), and made available through a web based user interface or XML based API.
