Water quality

How to measure water pollution in order to reduce harmful effects on humans and the environment

Water quality sensing

An important parameter for measuring water quality is the TOC level, which is the amount of carbon contained in an organic compound, i.e. a measurement of all organic contaminants in water. Therefore, TOC is often used as a non-specific indicator of water quality or the cleanliness of pharmaceutical production facilities.

How to improve water quality


High-end water purifiers and water dispensers provide the user with confirmation and thus assurance that the water is safe to drink. A TOC sensor installed after the filter stage monitors whether the filter is working or not.

Waterworks and Wastewater

Treatment of wastewater in local waterworks ensures that water is safe for the environment and healthy to humans.


Devices that support biologically active environment to produce biological material on a large scale.

Water quality trends

  • Filtration systems

    The number of residential water filtration systems in use are on the rise. People want to monitor water at the point of use.

  • Online monitoring

    The online monitoring of different water quality parameters optimizes cleaning processes and reduces costs.

  • Digitalization

    Digitalization enables online monitoring at multiple points of the distribution network.

  • Real-time data

    The desire to collect real-time data is causing an increase in online monitoring of water. This in turn increases measurement accuracy and allows authorities to act quickly in the case of an emergency.

  • Per- and polyfluorinated substances

    Investments in clean water and drinking water are increasing worldwide, including in the monitoring and remediation of per- and polyfluorinated substances (PFAS).

  • Regulations

    In the pharmaceutical industry regulations are very strict and quality level needs to be high. In water management standards of maximal concentration of contaminants are provided by the government. There is no clear test procedure mode.


Reliable monitoring stations that provide continuous data are an essential component of drinking water supply and environmental protection – both for dynamic process control as well as for continuous monitoring of water quality. World Health Organisation (WHO)

No WHO health-based guideline value has yet been established. TOC is an indicator of organic matter, particularly in raw water. TOC is a useful operational water quality parameter to indicate change. World Health Organization (WHO)
