91-05: Relationship of Biofilm Formation on Stainless Steel in Untreated Once Sidestream SofteningA study was initiated in a 23,000 gpm once through cooling water system for a 1200 megawatt nuclear plant that historically has experienced fouling with biofilms containing filamentous iron bacterial. The objective was to determine whether water quality variables correlate with biofilm formation. Stainless steel sampling stubs were exposed in this water system and biofilm developing on these stubs was quantified using cell counts, TOC, and total
With the greater restrictions on drift emissions that are now required in many locales
power plants and many other manufacturing facilities
Such a fill would have high performance
Preventing microbial growth in recirculating cooling systems is crucial to maintain productivity at your site and extend the life of your capital assets
Plant experience with an electrochemical biofilm sensor with integrated data acquisition and data analysis capabilities for monitoring biofilm activity on metallic surfaces and the use of that tool for optimizing biocide additions is described
Cooling tower performance test data published by EPRI and others is re-examined using a full compliment of modifications suggested by others to the standard Merkel method of analysis
Complying with increasingly stringent water discharge limitations has forced a re-examination of current cooling water treatment practices
