Our high efficiency fluoride removal technology is based on aluminium activated calcium hydroxyapatite – the most effective media for fluoride removal and minimum impact from competing ions. We supply our filters with options including automated backwash or just upflow in/out heads. Our fluoride removal filters can be used for potable and waste water treatment applications. The calcium hydroxyapatite can be regenerated once the media has been saturated.
Our fluoride removal technology is based on aluminium activated calcium hydroxypatite proven to be one of the most effective media for fluoride removal.
Hydroxylapatite, also called hydroxyapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH), but is usually written Ca10(PO4)6(OH)2 to denote that the crystal unit cell comprises two entities. Hydroxylapatite is the hydroxylendmember of the complex apatite group. The OH− ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonalcrystal system. Pure hydroxylapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colourations, comparable to the discolou®rations of dental fluorosis.

It is one of the most effective adsorbents of fluoride with much faster reaction times than Activated Alumina.
Aluminium activated hydroxyl apatite is the most
effective media for fluoride removal from water.
The defluoridation capacity of NEWDEF®1 is about 1~4 mg/g which is higher than normal media in the same conditions. The capacity is impacted by different raw water quality conditions including fluoride concentration、 temperature、co-existing ions etc..
Hydroxyapatite Features and Benefits
Figure 1 and Figure 2 demonstrate that the NEWDEF® media have higher performance than other common defluoridation materials under the same conditions. The treated water volume of NEWDEF® is About 5.09—11.7 times of activated alumina and 12.9—23 times of activated clinoptilolite
Comparison of various defluoridation media
Our composite tanks come with a number of options including Clack Automated Backwash Valves .
