BIoGEORGE™

Microbiologically Influenced Corrosion and Biofouling: Microbiologically Influenced Corrosion (MIC) is an ever-present threat to nuclear plant service water systems, particularly standby and redundant water systems — some safety-related — that spend half or more of their “operating lives” in what is essentially a wet layup state for extended periods of time. During those periods, microbes can create corrosion cells, even in stainless steel systems, where perforations can occur rapidly. In addition, the biofilms that form degrade heat transfer and can harbour pathogens such as Legionella bacteria. Fortunately, the BIoGEORGE™ monitoring system provides on-line, real-time information on biofilms on metallic surfaces. That information provides an early warning of biofilms on plant equipment before these rapidly forming films can get a toe-hold. The BIoGEORGE™ system also provides a reliable indication of the effectiveness of biocide treatments; critical information to optimize biocide and other chemical treatment selection, timing and duration of chemical additions, and concentrations.

Many BIoGEORGE™ users have improved the cleanliness of their systems while using less chemical, effectively paying for their BIoGEORGE™ system many times over in terms of improved system reliability and performance and lower chemical bills. The BIoGEORGE™ probe is available from Structural Integrity.
