Online measurement of microbiological contamination

Detect contamination in fresh and saline water

Fast and fully automatic, results in 15 minutes

Automated Water Microbiology

The ColiMinder is the most sensitive instrument available on the market for measuring the microbial quality of water (E. coli, Enterococci and Total Activity). A fully automated water quality measurement system it provides continuous monitoring of microbiological contamination regardless of the type of microbes present as well as algae, mould, yeast or biofilms.

Used in applications throughout the entire water cycle it is able to measure microbiological contamination of water samples within 15 minutes making it available as a parameter for process control.

ColiMinder measures the microbial contamination through the specific enzymatic activity of the respective target organism. The system achieves microbiological analysis of water without producing contaminated or hazardous waste and features fully automated sampling, measurement, cleaning and calibration. Low energy and emergency response versions are also available.

Parameters – E. coli, Enterococci and Total Activity

Monitoring Water Quality at the Paris Olympics

ColiMinder was a vital part of the water quality monitoring system designed to protect athletes at the Paris Olympics. ColiMinder analysers were installed in the Seine upstream of the site where the Triathlon events were held.

They provided an early warning that fecal contamination may be reaching the competition site by detecting E. coli, enterococci and total activity. The analytical data provided contributed to the decision to postpone the men’s individual triathlon due to the presence of E coli bacteria.

Monitoring the Heating and Cooling Water Cycle for Metal Production

The ColiMinder was installed in a European metal production plant to monitor the heating and cooling water circuits alternately, with the aim of controlling the disinfection intensity fully automatically based on the current contamination level data supplied by ColiMinder.

Benefits:

• Cost savings in disinfection treatment by adjusting the dosage to the actual degree of contamination
• Increased efficiency in the cooling water system through early detection of biofilms
• Avoidance of undetected microbial risks (e.g. legionella)
• Prevention of corrosion in the cooling water system due to chemical dosing
• Increased production, employee and product safety

Membrane Integrity 

Project

Herlev hospital a hospital in Denmark discharges wastewater into arecreational area and has to ensure membranes for treatment are working properly and no contaminated wastewater is drained.

Solution

Detection of defective membrane filtration modules (UF) in using ColiMinder for monitoring permeate. Peaks indicate defective filtration modules.

Outcome

Since 2016, ColiMinder serves as an early warning system for membrane integrity through 24/7 monitoring.
