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