Fluoride removal – NEWDEF ®Hydroxyapatite ...
Fluoride Removal using NEWDEF: Hydroxylapatite,
also called hydroxyapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH). Our media is specially treated and activated using aluminum to make it more effective. The principle of fluoride removal is based on the OH- ion in the media being replaced by fluoride producing fluorapatite.
It is one of the most effective adsorbents of fluoride with much faster reaction times than Activated Alumina. In comparative performance trials using Brisbane water containing Fluoride, aluminium-activated Calcium Hydroxyapatite outperformed other media including activated alumina and fluoride specific ion exchange media.
The De-fluoridation capacity of hydroxyapatite is about 2~4 mg/g which is superior compared to most medias under the same conditions. The capacity is impacted by different raw water quality including fluoride concentration, temperature, co-existing ions etc..
Fig below demonstrates that the NEWDEF® media( Hydroxyapatite) outperforms other common Defluoridation materials under the same conditions. The treated water volume before fluoride breakthrough of NEWDEF® is About 5.09—11.7 times of activated alumina and 12.9—23 times of activated Clinoptilolite.
