What are some good processes for removing fluoride from wastewater?
Thread Content
When the water volume is large, the precision required for fluoride removal from wastewater is very low; what are some good treatment processes?
Using a defluorination reactor, fluorine can be removed at atmospheric pressure. Compared to traditional distillation, the alkali neutralization method is much more effective.
When the fluoride removal requirements are not high, could lime (calcium fluoride precipitation method) be tried?
There are now many examples of resins specifically designed for fluoride removal; they are particularly suitable for handling large volumes of water, enabling the reduction of fluoride levels from several or dozens of ppm to below 1 ppm. For more information, please contact 13572450424
Resin adsorption can be considered; this method can reduce fluoride ions in the effluent to below 1 ppm. High-concentration regeneration liquid can be treated by lime precipitation. Feel free to get in touch if you’re interested

The company uses lime + defluoridant
For fluoride removal, active alumina, chemicals, hydroxyapatite, and ion exchange resins are used. In cases where fluoride levels are high, calcium salts are employed to precipitate it (usually it is possible to reduce the fluoride level to 10–15 ppm; this depends to some extent on the salt content). To achieve even lower levels, other treatment processes need to be combined. The specific process that is most cost-effective depends on the characteristics of the water quality
