A New Process For Sulfate Removal From Industrial Waters
Process Description. 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.
Gypsum Area Separation Walls In Townhouse Construction
· The separation layer is normally constructed of two layers of 1-inch thick gypsum board (drywall), rather than the 3/8-inch or 1/2-inch drywall used for surface walls.
