The core advantages of activated alumina in defluorination effect

2025-11-25

Among numerous defluorination methods (such as electrocoagulation and reverse osmosis), activated alumina's long-standing dominance is no accident. This is due to its series of irreplaceable core advantages in defluorination effectiveness. So, what are the advantages of activated alumina in defluorination?

1.Excellent Adsorption Efficiency and High Removal Rate

Activated alumina possesses a large specific surface area and abundant internal pore structure, providing a vast number of reaction sites for the adsorption of fluoride ions. Under optimized process conditions (especially with pH controlled between 5.5 and 6.5), it exhibits extremely high affinity and selectivity for fluoride ions, enabling the continuous and stable treatment of fluoride in influent from high concentrations to drinking water safety standards, with removal rates typically exceeding 90%.

2. Excellent Mechanical Strength and Long Service Life

Unlike some adsorbent materials that are easily pulverized and rapidly degraded, activated alumina particles are hard and have excellent wear resistance. During long-term water flow impact and repeated backwashing, it maintains its complete physical structure and is less prone to excessive powder generation leading to loss. Based on our long-term experience, the activated alumina produced by Zibo Xiangrun Environmental Engineering Co., Ltd. can last up to 5 years.

3. Reusable

When adsorption is saturated, it can recover most of its adsorption capacity through a regeneration process.

4. Strong Anti-interference and Stability

Activated alumina can adapt to complex water quality environments. Within a certain concentration range, it is not sensitive to interfering factors such as chloride ions and alkalinity in the water, and can still maintain good defluoridation capabilities. At the same time, its chemical properties are stable; it will not dissolve itself or introduce new toxic or harmful substances into the water, ensuring the safety of the treated water.
