Application field


ColiMinder™ is an online E.coli analyzer, capable to detect fecal contamination in wastewater within 15 minutes.

efficiency in process control by on-line e.coli monitoring

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

There is a huge potential of savings through adopting the disinfection intensity to the actual contamination, monitored by the ColiMinder, providing results within 15 minutes.

The timeline showing any change in microbial contamination is carrying precise and valuable information which had never been available before.

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

By measuring the enzymatic activity of fecal 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).
