More Information
Summary:The present invention concerns a process for treating waters containing at least two different dissolved inorganic salts which do not precipitate and/or crystallize in the same conditions by precipitation and ballasted flocculation, in which the ballast is produced in situ through size-controlled precipitation of one of the salts. This precipitate is then introduced as a ballast in a following flocculation step.
