Sludge Resource Recovery
Fluoride-Containing Wastewater Treatment generates large volumes of fluoride-containing sludge. Its poor quality prevents effective utilization, causing both resource waste and environmental risk.
Through innovation in operation and maintenance (O&M), Water Healer extracts synthetic fluorite powder from this sludge, maximizing the value recovered from waste and protecting non-renewable fluorite reserves.

Sources of Calcium Fluoride Sludge
Source Enterprise Type → Collection and Classification of Calcium Fluoride Sludge → Quality Classification: "Making the Best Use of Everything"
Photovoltaic, semiconductor and integrated circuit manufacturing → Calcium fluoride sludge (from crystallization precipitation of fluoride-containing wastewater) → High-quality calcium fluoride sludge → Hydrofluoric acid.
Inorganic and organic fluorochemical industry → Calcium fluoride sludge (from crystallization precipitation of fluoride-containing wastewater) → Medium-quality calcium fluoride sludge → Fluorite pellets.
Specialty glass such as touch screens and LCD panels → Calcium fluoride sludge (from crystallization precipitation of fluoride-containing wastewater) → Low-quality calcium fluoride sludge → Building materials and plastics.
