The saline processes in the daily business raw brine to salable table salt or road salt in various process steps. The foreign substances being present in the raw brine, such as potassium or bromide, cannot be completely removed in the pre-purification processes. Sulfate ions are only partially eliminated according to their solubility. Therefore, these substances must be removed (elutriated) from the system during the evaporation and crystallization process in soluble form. In the case of this saline, this elutriated mother liquor was formerly discharged into the environment. Thanks to the plant designed by EBNER in association with a partner, from this mother liquor the well-marketable product potassium sulfate could now be produced in addition to the table salt.
This process is unique in the world and was realized in cooperation with K-UTEC from Sondershausen, Germany.
