A-102 Plus can handle up to 300% calcium sulfate saturation on the brine side. CaSO4 saturation will vary according to concentrations of dissolved calcium and sulfates, temperature and salinity.

If you already have high sulfate levels, avoid or minimize any sulfuric acid dosing because it will add to the dissolved SO42-  ions in your feed water.

For calcium sulfate saturations > 300%, a specialty CaSO4 antiscalant should be used. The AWC A-104 can control calcium sulfate at saturations as high as 600%.
