Résumé

Fouling of heat exchanger and corrosion occurs in many industrial sectors which causes considerable economic losses and increases public health risks. Therefore, it is important to develop devices to monitor the formation/removal of fouling and the corrosion occurrence. Such devices permit to revisit the fouling/cleaning process and the corrosion sequences in order to minimize associated impacts and losses. In this work, a coda wave interferometry (CWI) based-sensor is used to monitor the fouling and corrosion status of surfaces. This paper aimed to give an overview of the experimental results obtained in order to assess the potential of this technique for various types of applications (wax cleaning, biofilm formation detection, fouling/cleaning monitoring for dairy derivatives-unpreceded results and corrosion formation). Overall, our work provided evidence that CWI method is applicable for monitoring fouling factor and corrosion of solid surfaces and could be easily implemented in a non-invasive way and on line.
