Description In the eastern zone of northern Sahara, several epidemiological studies have highlighted the problem of endemic fluorosis leading to dental and base deformities. The main cause of this case is attributed to ingestion, for a relatively long time, water drinking heavily fluorinated. Regarding the regions ( Ouargla, Touggourt , … ), various tests have been conducted, giving an idea about the presence of fluoride in the water drinking and our food diet. Our results also showed that these waters were characterized by significant mineralization and excessive hardness (>50 °F).

In the town of Touggourt, the drinking water supply of the inhabitants and the irrigation of the cultures are based on the exploitation of the underground waters of the aquifers of the Northern Sahara. One of the major issues for the sustainability of the use of this resource is the water quality of certain aquifers (albian). In this work we have experimented two partial softening processes, the lime precipitation and soda on the other hand membrane method by reverse osmosis. The softening is more or less low for the two processes tested and are respectively 54% and 94%. We have shown that water treatment with lime and excess soda more efficient, reverse osmosis membrane method is reduced to 90%. These tests also justified the choice of the most appropriate method technically and economically
