ColiMinder™ is an analyzer for real-time online bacteria monitoring
It is able to detect microbiological contamination in drinking water in 15 minutes.
Drinking Water Quality
The demand for drinking water water of adequate quality is constantly increasing; especially in large processes, there is a need to make them more efficient and thus more sustainable. Reuse of water and the development of a well-functioning circular economy are the most important building blocks of a sustainable society of the future. Drinking water processes as well as distribution networks are increasingly automated and automatically monitored. Both processes and process simulations require reliable input, relevant measurement data, in order to work efficiently or to map all relevant parameters reliably and correctly.
The ColiMinder has proven its capacity to ensure precise and reliable monitoring of bacterial and microbiological contamination
- at raw water intakes of drinking water plants
- in any process step of drinking water production
- in drinking water networks and storage tanks
How does it work?
By measuring the enzymatic activity of living microorganisms present in the sample, the ColiMinder™ is capable to monitor microbiological contamination in drinking water.
Due to ColiMinder’s short time to result, microbiological contamination is now available as a parameter for process control, also providing real-time warnings on exceeding threshold limits.
Just install the ColiMinder in or between any process step of your drinking water production: you will receive a new insight into microbial dynamics of your process.
The timeline showing any change in microbial contamination is carrying precise and valuable information which had never been available before.
How did it prove reliability?
The ColiMinder’s performance, reliability, stability and robustness have been evaluated, validated and proven in several scientific studies as well as in many customer applications all around the globe.
The results of technology validations by universities have been published in several peer reviewed scientific publications. E.g. in a scientific comparison study on Online microbial monitoring of drinking water: How do different techniques respond to contaminations in practice?, conducted by the University of Ghent and published in Water Research Journal, the ColiMinder was the only device to detect 100% of all contaminants in a national drinking water network
Internal validations are conducted regularly and form a part of our quality management.
The ColiMinder has proven that it can fully map the microbiological water quality of drinking water and is perfectly able to measure all kinds of contaminations, even if it was on the lowest level.
Can I do compliance testing with the ColiMinder?
The ColiMinder provides operational monitoring, as recommended e.g., by the WHO. It helps our customers to achieve the goals set out in compliance regulations by real-time monitoring of microbial contamination, enabling quick reaction on probable contamination events. It does not replace compliance testing.
