Cooling & Drinkingwater: ATP monitoring of biomass growth in waters - Water and Wastewater - Drinking Water

Monitoring Biomass in (Cooling Tower) Waters through ATP monitoring

The TOXcontrol can be used for ATP monitoring. Currently our company is doing research for further developments for this application on the TOXcontrol.

Monitoring the microbial population of cooling towers is necessary in order to maintain the proper operation of the system. Conventional methods for monitoring microbial populations work by culturing microorganisms, a time-consuming procedure that requires days or even weeks of incubation before the results are known. Biofouling can be well-advanced before treatment begins. In addition, it is believed that this technique does not detect the full range of microbial life present in cooling systems.

A more effective product is ATP-based technology, which makes possible real-time assessments of microbial populations. It measures the light produced when enzyme reagents react with ATP, a substance found in all living cells. On-line test can now be performed, results automatically read and corrective actions initiated within minutes of sample collection and analysis.

Adenosine-5-trifosfate (ATP) can best be described as the energy-carrier in all living cells. The ATPcontrol (a new, online ATP monitor) is specifically designed in order to automatically determine the level of microbial contamination in water samples, by which the effectiveness of additives and biocides on microbial growth can be determined. The ATPcontrol can be applied at all industrial systems where information is needed on the level of microbial activity. Within the monitor, the amount of light production correlates with the amount of ATP in the sample, which in turn is a relative measure for the microbial activity. The advantage of this system is the short determination time of several minutes.

The TOXcontrol can be used for ATP monitoring. Currently our company is doing research for further developments for this application on the TOXcontrol.
