Process Water Analysis

Analyze process water and industrial water to detect fecal or total microbiological contamination in any industrial process within 15 minutes.

Industrial Process Water Quality

Water use in industrial processes is subject to ever more stringent legal regulations and restrictions worldwide, and industry is obliged to reinforced re-use of water in closed cycles.

In water related processes microbiological water quality is of utmost importance as contamination can possibly reduce process efficiency, tie up a production plant or destroy a complete production range.

Knowing the microbiological contamination of industrial water in real-time enables to control the important process parameter of microbiological or fecal contamination to

  • control contamination level fully automated directly in the process
  • control process effectiveness
  • set early warning and thus enable quick reaction on contamination events
  • avoid tying up production processes
  • improve efficiency and efficacy of industrial processes
  • reduce direct process costs as well as follow-up costs caused by complete process interruption or contaminated products
  • protect environment through reduction of disinfection by-products
  • enable correlation of microbial contamination with events within the process
  • increase work and workers safety

Benefits of the ColiMinder

REAL-TIME WARNINGS

In case of contamination events.

MONITOR YOUR PROCESS PERFORMANCE

In order to increase process efficiency, safety and sustainability.

LEARN MORE ABOUT YOUR PROCESS

The result timelines (microbiological activity, transmission and intrinsic fluoresence) carry important additional information about the dynamics of the system.

SAFEGUARD YOUR WATER QUALITY

along the entire water treatment process and in your closed water cycle.

QUICKLY SCAN YOUR CLOSED WATER CYCLE

in case of microbiological contamination events, to identify source of contamination.

AVOID OVERDOSING

Adjust disinfection intensity to actual contamination.

The ColiMinder bacterial analyzer can be installed at any stage of a process and industrial water treatment for real-time monitoring of microbiological contamination.

The ColiMinder measures the specific metabolic (enzymatic) activity of the target organisms present in the sample.

The measured value provides information about the energy turnover of living organisms in the sample. Living organisms need energy, which they gain through their metabolism, so the metabolic activity reflects the energetic turnover of the existing microorganisms.

The measured activity directly indicates the faecal or microbiological contamination level of the water.

ColiMinder can automatically monitor any process step – critical control points – in water treatment processes, bottled water production, wastewater water treatment and discharge, industrial and process water treatment and discharge, providing a direct visualization of microbial dynamics of your processes. It also monitors any type of surface water, bathing and recreational water and raw water, be it fresh or saline water, providing a direct visualization of microbial dynamics of the respective water body.

The timeline displays any change in microbial contamination, providing precise and valuable information that was previously unavailable.

Since the results of the ColiMinder are available in near real time, microbiological water quality is now available as an evidence-based decision parameter. In addition, real-time alerts can be sent when defined bacterial contamination limits are exceeded.

The ColiMinder reliably detects any type of contamination, whether it is of fecal or microbial origin.

Different add-on modules are available to ensure stable and reliable sampling and results, even in harsh environmental conditions.

The measured enzymatic activity of the sample provides a direct answer to the questions: “how high is the faecal contamination of the sample?” and “how high is the microbiological contamination of the sample?”

Depending on the reagent used, the measurement results are specific for the corresponding target organism.

The results not only provide direct quantitative information about the microbial contamination of the product, but shape and course of the measurement timeline also contain valuable information about the dynamics of the microbiological load and thus allow conclusions to be drawn about the causes of changes. Depending on the reagent used, the measurement results are specific for the corresponding target organism.

A recent scientific study published in Water Research shows that the ColiMinder is the most sensitive instrument available on the market for monitoring microbial quality of water. Please see: Favere, J., Waegenaar, F., Boon, N., & De Gusseme, B. (2021). Online microbial monitoring of drinking water: How do different techniques respond to contaminations in practice?, published in Water Research Journal.

The reliability of the ColiMinder has been demonstrated in several installations where the devices have been providing reliable measurement results in continuous operation since 2015.

Maintenance:
Thanks to the sophisticated system for fully automatic cleaning and calibration, the maintenance effort is limited to refilling the consumables. Replacement of the silicone hoses is recommended every 2 years, otherwise no maintenance is required.

The ColiMinder instruments measure absolutely stable, no manual calibration is necessary as the instruments calibrate themselves automatically at regular intervals.

The ColiMinder can measure any type of sample without pre-treatment.

It has no problem with suspended solids or turbid samples. Even fluctuating background fluorescence has no effect on the measurement result. 

It has an IP65 protected housing and can measure in the 0°C to 40°C temperature range. 

The ColiMinder provides operational monitoring as recommended by the WHO, the EU Drinking Water Directive, and others.

Real-time measurement of current microbiological quality enables rapid response and correction, so the ColiMinder helps you to meet specified limits at the lowest cost and with the highest level of safety.

A correlation between standard lab results and ColiMinder results can be established and used internally but the system is not intended to replace compliance testing.

In contrast to classical culture-based laboratory methods, which are based on the cultivation of bacteria, the enzymatic measurement method of the ColiMinder is based on the direct measurement of the metabolic activity of the target organisms. There is therefore no direct and generally valid conversion between the two methods.

In general, however, a correlation table can be created through comparative measurements, which can then be used for conversion.
