Producing salt from seawater involves the selective recovery of pure NaCI, free of other soluble or insoluble salts and other substances. An appropriate quantity of seawater is concentrated through natural evaporation, which leads to the fractional crystallization of all salts contained a process based on their varying solubility.

This production method ensures greater control over the concentrations and quantities of the brines fed through the system, thus resulting in the unobstructed production of much better quality salt, this also increases dramatically the quantity of the salt produced as the average brine concentration in the system of ponds decreases drastically.
