03-19: Experience With On-Line Monitoring of Biofilms in Plant ApplicationsMicrobiologically Influenced Corrosion (MIC) of piping and heat exchanger materials in cooling waters has caused expensive unplanned outages, the need for local repairs, and, in some cases, complete system replacement. The control of biofilm on surfaces is the most effective tool for mitigating MIC, as well as for maintaining heat transfer in heat exchangers. Optimized treatments require accurate, on line monitoring of biofilm activity. Plant
