Dynamic Simulation of Biofouling and Corrosion Recovery

Abstract A laboratory recirculation test rig outfitted with corrosion coupons, linear polarization, annular heat transfer rods and a pressure drop tube were exposed to biological growth under simulated cooling water conditions. This experimental rig was designed to provide a means of quantifying the presence and intensity of biofilm in order to examine biofilm generation properties. The resulting biofilm was subjected to various biocide and dispersant treatments in order to evaluate heat transfer improvement and control of microbiological activity through monitoring planktonic and sessile bacteria levels. Verification of the accuracy of this monitoring system would prove useful in the laboratory to assess the potential of biofilm treatment strategies for field applications and for the control of microbially influenced corrosion.
