Abstract :
This work evolves around two objectives as its main focus of concern, on one hand, to study the physico-chemical quality of sanitary waters of the tourist area of Agadir and on the other hand, to study the thermodynamics predictions of the scaling by these waters.The follow-up of the physic-chemical quality of the water was realized at various points of the study area. It was carried out during one year. The concerned parameters are: The temperature, pH, electrical conductivity, total hardness, calcium hardness, magnesium hardness and the concentrations of the ions (HCO₃⁻, CO₃²⁻, SO₄²⁻, NO₃⁻, Cl⁻, OH⁻, Na⁺, K⁺...).The obtained results show that the calcium and magnesium contents are high. The hardness ranges between 25 and 55.63 °F. The complete alkalimetric title ranges from7.5 to 34 °F. The complete alkalimetric title ranges from7.5 to 34 °F. The hardness values show that 85 % of waters are very hard. Based on the obtained results of the physico-chemical analyzes, a study of the thermodynamic predictions of scaling was carried out using the Legrand-Poirier-Leroy (LPL) method.
