Contribution à l’étude des phénomènes d’entartrage par les eaux géothermales. Partie II: Etude de l’influence des compagnons de cristallisation
Written by sctunisie no commentsThe effect of crystallisation companions (Na+, Cl-, Mg2+, SO42- and Ca2+) of carbonate calcium was been studied by LCGE technique. This study shows that magnesium is the responsible of the aragonitic form of deposit scale in geothermal water. In an other hand, the permanent hardness (Ca2+) is the determinant factor of the abnormal Kinetic behaviour, comparing to pure calco-carbonic system. The sulfate ions slightly delay the CaCO3 germination but the Na+ and Cl- ions are inactive.
