Fluoride compounds are salts that form when the element fluorine combines with minerals in soil or rocks. Many water systems add fluoride to drinking water. High levels of fluoride are also found naturally in some areas. Studies have shown that excessive consumption of fluoride can damage bone tissue and discolor or mottle teeth.
Fluoride can be removed from drinking water by using reverse osmosis. Reverse osmosis has been shown to successfully treat water with fluoride concentrations up to 12 mg/l.
Reverse osmosis systems WATEX WRO type.
