Defluoridation of brackish northern Sahara groundwater

High fluoride concentrations in water cause problem in terms of public health. Owing to its efficiency reverse osmosis (RO) was considered for water defluoridation. However this technique is not selective. The recovery by means of brackish water RO system is therefore limited by salt precipitation. A computer calculation program was developed to determine the activity products aCa2+.aCO32

Fluoridation by country Wikipedia

Defluoridation is needed when the naturally occurring fluoride level exceeds recommended limits. In 2011 the World Health Organization suggested a level of fluoride from 0.5 to 1.5 mg/L (milligrams per litre) depending on climate local environment and other sources of fluoride. Bottled water typically has unknown fluoride levels.
