Three of the simplest methods of doing for de fluoridation of water._
1. Reverse Osmosis,
2. Distillation and
3. Activated Alumina Defluoridation.
The first two methods are excellent for water purification in general though one must add supplements to distilled water, due to it’s lack of minerals it is potentially unsafe to drink in large quantities. A fourth manner is by use of Bone Char Carbon which is 90% effective; this method is best used in tandem with other purification techniques.
Bone Char Carbon
“Bone char is a granular material produced by charring animal bones: the bones are heated to high temperatures (in the range of 400 to 500 °C) in an oxygen-depleted atmosphere to control the quality of the product as related to its adsorption capacity for applications such as defluoridation of water and removal of heavy metals from aqueous solutions.”
