Determination of treatment parameters for fluorine-containing wastewater
Thread Content
Has any friend carried out two-stage chemical removal of fluoride ions? How are the pH of each section and the dosage of lime and CaCl2 determined? Are there any engineering examples to ensure fluoride ions are below 10?
F ions are relatively difficult to remove; we have worked in electronics factories. After RO, DTRO and MVR evaporation are required as well. I’ve forgotten what specific level of waste F is.
Our company is capable of achieving zero discharge for fluoride-containing wastewater; feel free to contact me if you need assistance
It’s hard to determine without knowing the content
