Measurement of Biofilm Thickness: An Effective Legionella Risk Assessment Tool
The best way to prevent the risk of bacterial growth in water systems is to monitor and to control the microorganisms (biofilm) attached to pipe walls. Three years of laboratory research led 2 CNRS teams (UMR 6008 and UPR 15) to develop a tool designed to determine the average biofilm thickness. The average biofilm thickness measurements carried out on pilot plants fed with natural water were sufficiently accurate and sensitive to monitor the formation and development of biofilm in a water system ...
