Opis:: El-Oued is known for some diseases caused by fluoride concentration in drinkable water. To reduce it , a sample with the biggest content among many sources was chosen. A comparative study between the precipitation with calcium salts [Ca(OH)2, CaCl2, CaSO4] and the coagulation with the following salts [Al2(SO4)2•18H2O, Fe2(SO4)2•H2O, FeSO4] was done. Finely we studied the parameters influencing (the mass , pH, temperature) to choose the best conditions in order to get better reduction yield.

Opis:: El-Oued is known for some diseases caused by fluoride concentration in drinkable water. To reduce it, we have chosen a sample with the highest content of fluoride among many sources in order to coagulate it with Al2(SO4)3ź18H2O, Fe2(SO4)3źH2O and FeSO4. In order to get better reduction yield of fluoride, a study has been done on the influencing parameters (concentration, pH, temperature) to choose the best conditions. The remove of fluoride is favorable at low concentration of Al2(SO4)3, at room temperature and normal acidity.

Opis:: In this study, we are interested in evaluating the performance of a system for purifying wastewater by plants in an arid climate. The treated water is wastewater from domestic sources in the region of the old Ksar Temacine (Wilaya of Ouargla, South-East of Algeria). The results show good yields for organic and particulate pollution. Drawdown rate of approximately 97.49 % of Suspended Solids (SS), 90.85 % of Chemical Oxygen Demand (COD), have been achieved. The system effectively removes nitrate pollution 100 % of ammonium and phosphorus pollution moderately 62.28 % of orthophosphates. The system shows a very high removal of total coliforms (90 %).
