Sodium chloride (NaCl), or common table salt, is a water soluble and colorless crystalline solid. The solution of dissolved salt in water is called brine.
One way of obtaining salt is from brine wells (solution mining). Vaisala K-PATENTS® Process Refractometer measures the sulfate levels of the brine in the crystallizing evaporator. By measuring the amount of impurities, the crystallization process can be controlled better, thus giving high purity salt with reduced production times.
