Drinking Water Industry

Catchment. Treatment. Distribution.

From source to faucet, drinking water needs purification steps to arrive clean and without bacterial contamination at your home. These water treatment steps encompass pretreatment, water treatment, filtration and disinfection – and all can be supervised online with the environmental- and user-friendly BactoSense Online and BactoSense Multi.


Further applications include the monitoring of microbial populations in reservoirs and water catchments, pipe flushing and general quality control. You can even manage whole distribution networks with multi-point sampling.


The compact design of BactoSense makes it a great transportable and reliable companion as well as a stationary solution in any water plant – ready to be used anytime, anywhere by everyone.

Spring, surface and ground water are online monitored to evaluate its quality. Source quality can vary through time due to weather conditions.

BactoSense can be used to timely retrieve water from safe sources and avoid suspicious ones.

During this coarse filtration, particles in suspension are separated and dissolved substances are diminished.


BactoSense ensures the elimination of potential microbiological contaminants by tracking the bacteriological reduction during processes.

Whether a light or a strong filtration is required, the removal of potential microbiological contaminants is monitored. Its efficiency is controlled and its level of detail can go down to the individual module if necessary.

Additional steps might be required. Monitoring regularly such processes gives a direct feedback on the filtration integrity and can trigger protocols: e.g. cleaning or regeneration of a biological membrane.

Sometimes water must be adjusted (minerals, hardness). It is possible to look at the effect on the microbial flora during these processes.

Monitoring disinfection steps warrants a microbial safe production. BactoSense tracking can trigger disinfection processes or drive an automatic dosing.

Verifying the microbiological safety of the produced water is essential. In 20 minutes, BactoSense assesses the water quality and alerts the supplier of any variations, at any time, to better protect the end user.

Distribution Network
