The BIoGEORGE is a probe with output device monitoring microbial fouling, i.e. biofilm activity. It has a warning system with led's for unacceptable biofilm growth, whereby the efficacy of biocide dosing can be read directly. Fouling by microorganisms, i.e. biofilms, in cooling-water systems is one of the most important causes of heat transfer reduction in heat exchangers.
Indeed, the occurrence of a biofilm in heat exchangers amounts to an estimated annual loss of some billions of Euro's on a global scale. Also, biofilmactivity in cooling-water systems increase the risk of corrosion damage by MIC (Microbial Influenced Corrosion). Furthermore, the occurrence of pathogens in biofilms and circulation water, like Legionella and Acanthamoeba, increases the health hazards of employees working nearby recirculating cooling water systems.
In order to mitigate both waterborne microorganisms and biofilms, biocides and additional chemicals are applied on a large scale. The BloGEORGE™ on-line monitoring system registers the actual status of the formation and activity of a biofilm and provides an early warning of unsatisfactory conditions. As a result, the possibility exists to optimize the applied biocide dosing by providing feedback directly to the operator, giving in a potential cost reduction. In addition, an optimal controlled biofilm reduces all microbial effects, such as MIC and reduced heat exchange, to an optimum.
The system is used by KEMA to alert operators for the necessity of water treatment or to assess the effectiveness of a water treatment regime, thereby minimizing the risk of fouling and corrosion while reducing the costs of the mitigation approach.
