Fluoride-containing wastewater treatment
Thread Content
To treat fluoride-containing wastewater, we use calcium carbide slag and aluminum sulfate; the fluoride concentration is around 15. The treatment process is demanding, as there is a large amount of calcium carbide slag and fluoride sludge involved. Is there a better management method for this approach? Are there any other good treatment processes?
Someone upstairs said that calcium chloride is used to produce a calcium fluoride precipitate
Generate calcium fluoride precipitate, tongyi
Generally, precipitation treatment is used, which results in a very low fluoride content. If further treatment is required, the appropriate process must be chosen to remove fluoride.
Is it possible to achieve below 1 ppm using calcium salts? It seems it can’t be done?
The combined use of lime and calcium chloride can reduce levels to 3 ppm; other methods are then required

In addition to fluoride removal, traditional processes for dealing with calcium waste generate a large amount of sludge. The initial results are satisfactory, but it’s not possible to reduce fluoride levels to below 15 PPM, and the reaction process is slow. The cost of treating hazardous waste is also high. Our company specializes in advanced treatments for fluoride ions. The fluoride removal agents we have developed do not require any changes to existing processes; they are easy to use – simply add them to the mixture, and fluoride levels can be reduced to below 3 PPM.
