Fluoride Removal From Industrial Wastewater Saltworks

Sep 13, 2019 During CaF 2 precipitation, lime is used to neutralize any waste acids in the fluoride wastewaters. With fluoride concentrations less than 1,000 mgL, lime is often selected as the sole calcium source to precipitate fluoride. Lime has a low solubility at 0.18 by weight so for wastewater with high fluoride concentrations it used together with calcium chloride, which has a high solubility.
