WH-CADF® Induced Enhanced Advanced Fluoride Removal Process

Solving the challenge of meeting tightened fluoride discharge standards.

Advancement

  • Meets the requirements of different discharge standards, with high fluoride removal efficiency.
  • Skid-mounted modular equipment with a small footprint and short construction period.
  • High chemical utilization, delivering a 40% lower cost than conventional processes.
  • Proven in fluoride removal and upgrade retrofits across multiple scenarios, with a wide application range.

Process Features

High Volumetric Efficiency

The reactor incorporates a micro-tube fluidized reaction zone, a sludge–water separation zone and a seed crystal recovery zone. The functional units work in synergy within a compact structure with a small footprint. A jet mixer ensures thorough mixing of the fluoride-containing wastewater and the fluoride removal agent, improving chemical utilization and enhancing fluoride removal performance.

High Fluoride Removal Efficiency

The micro-tube fluidized reaction zone intensifies turbulence, inducing crystallization between fluoride ions and the fluoride removal agent for rapid precipitation and improved fluoride removal efficiency.

Applicable Discharge Standards

Lime / Calcium Chloride Method 20 ppm
WH-CADF® ≤ 1.5 ppm
1.5
