Fluoride Removal Filler

The conventional fluoride removal using activated alumina takes advantage of its excellent adsorption properties, which are attributed to the unique structure of activated alumina. The number of oxygen ions in the second layer of activated alumina is double that of the first layer, and these oxygen ions are connected to aluminum ions. As a result, aluminum ions are exposed on the surface, enabling them to bond with fluoride ions (F—), thereby achieving fluoride removal.

The fluoride removal filler developed by your company for fluorine-containing wastewater is based on conventional activated alumina. It undergoes modification with a specific modifier and then a secondary calcination activation. During the modification process, the water molecules adsorbed by the alumina form hydroxyl groups with varying activity levels. The calcination activation step enhances the active sites between the hydroxyl groups and metal ions, thereby improving the fluoride removal capability of the adsorbent.

Precautions for use

1: The fluoride removal process using modified activated alumina can vary in effectiveness depending on the type of ions present in the water and the pH level. To achieve optimal fluoride removal, it is necessary to conduct small-scale tests to determine the best influent pH.

2: During the fluoride removal process with modified activated alumina, the exchange of ligands can affect the pH of the water, leading to an increase in pH to some extent.
