A New Process For Sulfate Removal From Industrial Waters
A New Process For Sulfate Removal From Industrial Waters

The most common method for removing high concentrations of sulfate from water is through addition of hydrated lime (Ca (OH)2), which precipitates calcium sulfate: Na 2 SO 4 + Ca (OH) 2 => CaSO 4 + 2 NaOH Calcium sulfate, which hydrates to become the common mineral gypsum, has a solubility of approximately 2000 mg/L as sulfate.
