ABSTRACT: Consumption of safe drinking water is
essential to human health. The excess of certain elements in drinking water
causes health problem for people consuming these waters. In Senegal, the
excessive levels of fluoride and salts found in the groundnut basin cause
public health problem such as dental and/or skeletal fluorosis. Thus, the
treatment of such waters is essential before consumption to prevent health
problems. For a partial removal of fluoride and salinity, we tested the
performance of two commercial nanofiltration membranes namely TFC-SR3 and SelRO
MPF-34 at laboratory scale. The results showed that TFC-SR3 membrane was very
efficient with rejection rates of 83% - 96% for fluoride ions and 89% - 96% for
salinity. For SelRo MPF-34 membrane, retention rates of 25% - 52% were obtained
for fluoride ions and 24% - 60% for the salinity.
