Neither too much nor too little
Accurate dosing ensures effective treatment while avoiding excessive use of chemicals: underdosing exposes users to health risks, overdosing spoils the taste of the water and increases disinfection by-products.

Drinking water
Supplying safe drinking water is one of the most important responsibilities of any infrastructure. Water utilities, operators and private plants must comply with strict health limits while keeping chemical consumption and operating costs under control.
- Disinfection
- pH control
- Residual in the network
- Traceability
The sector
Safe water from treatment to point of use
Drinking water treatment requires precise control of a few key processes: disinfection, pH adjustment and stabilisation, removal of contaminants and microorganisms, and maintaining the disinfectant residual throughout the network.
Processes
The processes to control
Disinfection
With chlorine, chlorine dioxide, monochloramine or ozone, dosed in proportion to flow or controlled by the reading.
pH
It must be adjusted and stabilised: the effectiveness of chlorine and the aggressiveness of the water towards pipes depend on it.
Contaminants
Iron, manganese, turbidity and microorganisms are reduced by oxidation and filtration upstream of disinfection.
Residual in the network
The disinfectant residual must reach the most distant point of use without exceeding legal limits.
Safety
Safety and compliance
Critical parameters
Instruments continuously measure disinfectant, pH and turbidity and adjust dosing accordingly.
Alarms
Out-of-range values, lack of flow or of chemical are signalled and, when necessary, stop dosing.
Traceability
Recorded readings, available remotely, document the treatment over time, as required by water safety plans.
