Keywords:

Barium sulfate (BaSO4), Brackish water/brines, Calcium sulfate (CaSO4), Saturation, Strontium sulfate (SrSO4), Supersaturation, supersaturation of barium sulfate/strontium sulfate/calcium sulfate, dehydrate (gypsum) (in brackish water/seawater/brines), practice, ICS Number Code 13.060.30 (Sewage water)

Additional information

1. Scope

1.1 This practice covers the calculation of supersaturation of barium sulfate, strontium sulfate, and calcium sulfate dihydrate (gypsum) in brackish water, seawater, and brines in which barium, strontium, and calcium ions either coexist or exist individually in solution in the presence of sulfate ions.

1.2 This practice is not applicable for calculating calcium sulfate dihydrate supersaturation if the temperatures of saline waters under investigation exceed 95°C. At temperatures above 95°C, hemianhydrate and anhydrite would be major insoluble forms.

1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
