Reduce calcium sulphate solubility when dissolving rock salt

In most rock salts, calcium sulphate (CaSO4) is the main impurity. It dissolves together with sodium chloride when salt is converted to brine. The anhydrite solubility reduction (ASR) technology is based on the ability of certain chemicals, in ppm concentrations, to substantially reduce the solubility of calcium sulphate in brine. The ASR reagent chemically bounds to the calcium sulphate and remains in the brine cavern or in the salt dissolver. The significant improvement of brine quality results in purer salt as well as reduced costs for brine purification.

Salt Partners avail of salt testing facilities that are capable to accurately predict the performance of the ASR reagent with specific salt and brine (refer to salt test).

Salt Partners calculate the cost of salt, brine purification chemicals and other economic factors against the cost of the investment in the ASR installation and the consumption of ASR reagent with computerised evaluation programs relevant to most of the known applications. A simple questionnaire is available for this purpose on demand.

Based on the test results, guarantees for the performance of the ASR technology are determined.

The blend of the chemicals and additives is available as the anhydrite solubility reduction reagent (ASR reagent) from Salt Partners either for industrial or for food applications, together with the necessary services, installations and guarantees.
