Groundwater Fluoride Removal Filter Media

—Spherical Adsorbent REFsorb

REFsorb is a spherical inorganic fluoride removal adsorbent specifically designed for drinking water and groundwater defluoridation. Below is a systematic summary of its performance based on current data:

Core Parameters of REFsorb Spherical Adsorbent

Performance in Drinking Water Defluoridation

• Effluent Quality: Can stably reduce fluoride ion concentration in water from 5–50 mg/L to <1 mg/L, complying with the GB5749-2022 drinking water standard;

• Applicable Scenarios: High-fluoride groundwater, rural centralized water supply, small water plants, school direct drinking water systems;

• Operation Method: Fixed-bed adsorption, no chemical dosing required, simple system;

• Service Life: Can last for over 3 years under normal operating conditions;

• Regeneration Capability: Supports NaOH alkaline washing regeneration with a recovery rate >95%, low operating cost.

Advantages of Spherical Structure

• High Mechanical Strength: Resistant to pulverization, suitable for long-term water flow沖刷;

• Low Head Loss: Spherical particles offer low flow resistance, suitable for gravity filtration systems;

• Uniform Particle Size: Easy to fill, backwash, and replace, convenient maintenance;

• Environmentally Friendly and Non-Toxic: Certified by NSF/ANSI 61, suitable for drinking water treatment.

REFsorb Spherical Fluoride Removal Adsorbent is a high-efficiency, renewable, safe, and drinking water system-compatible defluoridation material, particularly suitable for:

• Treatment of high-fluoride groundwater;

• Small centralized water supply in rural areas and towns;

• End-point fluoride removal in direct drinking water systems for schools, hospitals, and communities.
