Fluoride Removal Agent

Excessive fluoride in water has become a major concern for both drinking water safety and industrial wastewater discharge compliance. Long-term consumption of high-fluoride water can lead to dental fluorosis, skeletal problems, and neurological damage. Fluoride removal agents are specially designed chemicals used to efficiently eliminate fluoride ions from water, making them essential in both municipal and industrial water treatment.

1. What Is the Function of a Fluoride Removal Agent?

The core function of a fluoride removal agent is to rapidly reduce fluoride levels in water to meet drinking water standards (generally ≤1.0mg/L). It is widely used in treating:

• Drinking water

• Industrial effluent (from aluminum processing, electroplating, glass manufacturing, etc.)

• Groundwater purification projects

2. How Does a Fluoride Removal Agent Work?

There are three main working mechanisms:

-Adsorption and Precipitation
Metal-based agents (e.g., aluminum or iron salts) react with fluoride to form insoluble compounds that precipitate out of the water.

-Ion Exchange
Special resins or natural mineral-based agents exchange ions with fluoride to remove it from the water.

-Coagulation Synergy
When combined with coagulants like PAC, fluoride removal agents enhance sedimentation and water clarity.

3. Common Application Scenarios

-Rural Drinking Water Projects
Ensures fluoride-safe drinking water in regions with fluoride-rich groundwater.

-Industrial Wastewater Treatment
Applied in aluminum, glass, and electronics sectors for compliant fluoride discharge.

-Municipal Water Treatment
Incorporated into public water systems for added fluoride safety.

– Lab and Research Use
For precise defluoridation in controlled or experimental environments.
