Drinking Water

ColiMinder™ is able to detect total microbiological contamination in drinking water in 15 minutes.

Drinking Water Quality

The quality of drinking water is essential as water is distributed throughout networks reaching thousands of people within a short period of time. Besides contamination resulting from external sources and being spread within a network, bacteria and microorganisms are able to grow within the system and act as an internal source of hazard.

In drinking water applications the ColiMinder™ monitors for “Total Activity” (alkaline phosphatase activity) as monitoring this parameter the presence of living organisms of any kind is leading to an increased measurement signal. This parameter reflects the full spectrum of organisms that might have entered the system or are growing within.

How does the coliminder detect microbiological contamination real-time in drinking water?

By measuring the enzymatic activity of living microorganisms present in the sample, the ColiMinder™ is able to detect total microbiological contamination in drinking water.

A first step into a new era: microbiological contamination measurement is available in real-time, enabling a dramatic increase in efficiency & safety of water treatment process for all water related processes.

Due to the short time to result (15 minutes), the microbiological parameter is now available first for process control and early warnings.
