Contribution to the study of scaling mechanisms. Application to electric anti-scaling apparatus

In order to precisely study scaling mechanisms, this research thesis first aims at a deeper understanding of natural waters and their equilibriums by developing the Legrand and Poirier graphical method, and then studies the conditions for obtaining deposited products by electrolytic way on metal substrates the surface condition of which allows a better monitoring of the first stages of the phenomenon. The author also addresses the determination of an operating principle for electrical anti-scaling systems, and the development of a test method for the assessment of their efficiency. The author also identifies some rules allowing this efficiency to be improved in the case of natural waters
