For this, add the soda ash and flocculant type polylactamide to the product, open until 13-14. The concentration of magnesium ions in the economy after the stage of installation and centralization is reached at its maximum value.

Abstract

Cette invention concerne un procédé de traitement d'eaux minéralisées à base de sulfates et de chlorures dans lesquelles le rapport entre les concentrations de chlorures et de sulfates est inférieur à 1:6. Ce procédé comprend des étapes de préparation de l'eau, de concentration, de cristallisation et de centrifugation. La cristallisation se fait pour un contenu total en sels de 50 à 100 g/l, tandis que la concentration se fait selon un procédé d'osmose inverse à une pression de travail qui varie de 1,5 à 4,0 Mpa. Le rapport entre les concentrations de sulfates et de chlorures lors du processus de concentration augmente d'au moins 2,5 fois. Grâce au renvoi dans le cycle de traitement des solutions restantes qui sont obtenues après la cristallisation et la centrifugation, il est possible d'accroître encore le rapport entre les concentrations de sulfates et de chlorures avant l'étape de concentration. Le mélange des solutions restantes à l'eau de départ permet d'accroître ledit rapport entre les concentrations d'au moins 18 %. Le mélange des solutions restantes à l'eau de départ ainsi qu'à l'eau après chaque étape de préparation de l'eau permet d'accroître ce même rapport d'au moins 3 % dans l'eau de départ, et d'au moins 17 % dans l'eau devant être concentrée. L'étape de préparation de l'eau décrite dans ce procédé peut par exemple comprendre l'élimination des métaux lourds et des solides à base de calcium et de magnésium.
