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 aluminIum 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.

Benefits of Calcium Hydroxyapatite media:

• Much faster contact times compared to activated alumina.
• Is a natural occurring mineral that is often used as a natural mineral supplement.
• Does not release any harmful substances into the water that is to be treated.
• Can be used for waste water treatment .
• Has a higher absorption capacity compared to other media used for de-fluoridation.
