ACFP® Alkalinity-Regulated Calcium Fluoride Sludge Purification Process achieves calcium fluoride purity of ≥90%, high fluorine resource recovery, a particle size of 20–60 μm, diverse resource recovery applications, and low harmful impurities.

Through seed-induced crystallization, circulating fluidized-bed crystallization, and fractional crystallization, it removes fluoride from wastewater to compliance levels while extracting synthetic fluorite powder suitable for hydrofluoric acid production.

The fluoride-containing wastewater treatment process generates large amounts of fluoride-containing sludge. The sludge is of low quality and cannot be reasonably and effectively utilized, resulting in resource waste and environmental risks. Through innovation in O&M technologies, Water Healer refines synthetic fluorite powder, maximizing the conversion of waste into value and protecting non-renewable fluorite mineral resources.

China's annual mined fluorite output is 4.5 million tonnes. If fluorite were recovered from wastewater, primary ore mining could be reduced by 30%, delivering enormous economic and especially environmental value.
