Revolutionizing Fluoride Removal: Advanced Technologies for Efficient, Cost-Effective Solutions

Harm of Fluoride:

Adequate fluoride is essential for the human body, playing a preventive role against tooth decay. However, fluoride is an accumulative toxin; its excessive buildup can lead to various health issues. Initial symptoms include rheumatic-like pain, neck and lumbar pain, stiffness, limb pain, numbness, followed by mobility issues, joint deformities, dizziness, tinnitus, nausea, loss of appetite, and constipation. Clinically, this results in fluorosis teeth, with yellow, brown, or black spots, corrosion, and increased susceptibility to wear and fracture.

The fundamental reason behind these conditions is the impact of fluoride on calcium and phosphorus. Excessive fluoride disrupts the normal ratio of fluoride to calcium in the body, leading to the formation of a large amount of calcium fluoride. Calcium fluoride is prone to deposition, causing increased bone density, bone hardness, bone growth (particularly evident in muscles, tendons, and ligaments), thickening of bone cortex and periosteum, uneven surfaces, ligament calcification, and narrowing of the intervertebral canal. Additionally, fluoride deposition in the bones often leads to decreased blood calcium, influencing phosphorus deposition, resulting in increased blood phosphorus and fatigue.

Traditional Fluoride Removal Processes:

There are various methods for fluoride removal from water, broadly classified into five categories: reverse osmosis, electrodialysis, electrophoresis, coagulation and precipitation, and ion exchange. Below is an evaluation of these treatment processes.

Shortcomings of Traditional Fluoride Removal Processes:

  • Reverse Osmosis: While effective in fluoride removal (minimum removal rate of 70%), it suffers from low water utilization rates (maximum 70%) and high initial and operational costs.
  • Electrodialysis: Limited to larger water treatment systems, high initial setup costs, and high operational expenses (including electricity, chemical, maintenance, and replacement costs) make it economically unviable for many users.

Advanced Fluoride Removal Technologies:

Advanced Technology One: Fluoride Scavengers

Synthetic fluoride scavengers, composed of compounds like “composite molecular sieves” and non-metallic materials, rapidly form hydroxyl-chelated ions with fluoride ions in water, facilitating their removal.

Advanced Technology Two: “F.F Composite Molecular Sieves”

Specifically designed for selective adsorption of hydroxyl-chelated ion groups. “F.F” possesses a large surface area and, through special modifications, quickly adsorbs hydroxyl-chelated ion groups, releasing them during backwashing.

The entire fluoride removal system operates fully automatically, minimizing manual interventions such as measurements, automatic dosing, flushing, flexible scheduling, and digital displays.

Furthermore, the system boasts a remarkably high water utilization rate, reaching 99%, conserving substantial water resources


The QDK-type new-generation, non-regenerative fluoride removal system pioneers a path for energy-efficient, water-conserving, cost-effective, and efficient fluoride removal equipment. The widespread adoption of this technology is poised to save significant national funds and contribute significantly to human health and well-being.
