Desaturating the stream of metals and gypsum is important to prevent scaling on equipment and is performed by dilution and lowering the temperature (remember that calcium salts are inversely soluble). The pH of the wastewater stream is then raised to between 8-10 using, calcium hydroxide, (Ca(OH)2) or sodium hydroxide (NaOH).
