Waste Water

ColiMinder™ is capable to detect fecal contamination in waste water within 15 minutes.


Waste water processes are the largest water treatment processes with disinfection efforts involving a huge amount of chemicals/energy. In waste water treatment the contamination levels also show extreme diurnal variations.

There is thus a huge potential of savings through adopting the disinfection intensity to the actual contamination.

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

By measuring the enzymatic activity of faecal indicator organisms (E. coli and Enterococci) present in the sample. The ColiMinder is capable to determine and show the level of microbiological contamination of waste water in real-time.

A first step into a new era: microbiological contamination measurement is available in real-time, enabling to exactly address the actual contamination level.

Especially in waste water there is high potential of savings due to the strong diurnal variations (see timeline below).
