During our work on the phenomenon of scaling observed in the sanitary water transport pipes of the tourist sector in the city of Agadir, we carried out a one-year follow-up (January to December 2015) to determine the physical and chemical quality of these waters. Sampling was conducted from four sampling points, well distributed throughout the study area and involving 84 water samples. For each sample, the parameters measured are: temperature, pH, conductivity, total hardness and concentrations of HCO3−, Ca2+, Mg2+, Na+, K+, SO42−, NO3−, Cl− and OH− ions. Indeed, the physico-chemical quality monitoring shows that the hydrotimetric title varies between 25 °F and 55.63 °F and the complete alkalimetric title varies from 7.5 °F to 34 °F. For the kinetic study of the scaling power, which is the subject of this work, we selected four samples of high hardness from the 84 samples analysed. This study was carried out using the controlled degassing method “LCGE” and showed that the waters studied are scaling. The germination time Tg varies between 38 and 84 mn. The identification of new scale inhibitors to prevent scale formation in the sanitary water transport pipes of the tourist sector in Agadir will also be addressed.
