Surface & bathing Water
ColiMinder™ is an online E. coli analyzer capable to detect fecal and microbiological contamination in surface and bathing water within 15 minutes.
essential source
Surface water is an essential source for drinking water, also serving people as bathing and recreational waters. Its microbiological quality is of essence as people get in direct touch, thus its microbiological contamination is affecting directly to people’s health.
The ColiMinder is deployed successfully world-wide in many different installations to monitor fecal contamination in
– Surface water such as sea, lakes, rivers
– recreational and bathing waters
– raw water intake for drinking water production
– outlets of sewage / wastewater treatment plants draining into surface waters
to ensure safety and enable quick reaction in contamination events.
How does the coliminder detect microbiological contamination real-time in surface and bathing water?
By measuring the enzymatic activity of living faecal indicators (E.coli or enterococci) present in the sample, the ColiMinder is able to determine the level of faecal contamination in surface and bathing 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 time for process control and early warning.
