Sodium sulphate is a solid inorganic salt well soluble in water (161-190 g/l at 20 oC) with a melting point of 884 oC and density of 2.7 g/cm 3. In water solutions it is fully dissociated to sodium and sulfate ions. In water sodium sulfate completely dissociates into sodium and sulfate ions. The ions cannot hydrolyse. In

The simplest technology for reducing high sulfate concentrations is lime precipitation. Adding calcium as pebble lime, hydrated lime, or limestone can precipitate calcium sulfate (gypsum) and reduce sulfate concentrations to the solubility limit of 1,500-2,000 mg/L. Concentrations already below this level will generally be unaffected by lime ...
