The fluoride concentration in the treated liquid is less than 5 mg/L, making it possible to reduce fluoride to low concentrations more easily than with conventional methods.
Our company conducts fluoride treatment based on a method that removes fluoride as calcium fluoride by adding calcium salts to precipitate it. After the removal of calcium fluoride, a defluorinating agent is added to the supernatant to generate calcium precipitate, which adsorbs and removes fluoride. The generated calcium precipitate is reused as a calcium source in the process of precipitating calcium fluoride. Therefore, sludge derived from additives does not occur. 【Features】 ■ The treated liquid contains almost no calcium. ■ No precipitate other than calcium fluoride is generated. ■ Existing equipment can be repurposed. *For more details, please refer to the PDF document or feel free to contact us.
