Minimizing fluoride by coagulation on iron(III) hydroxide in drinkable water from Oasis region of Algeria

Atia D., Hoggui A.

International Letters of Chemistry, Physics and Astronomy

2013

Vol. 7, iss. 1

23--29

The drinkable water in oasis region of Algeria contains high quantity of fluoride which causes dental fluorosis. To reduce fluoride, we have chosen a sample with the biggest content of fluoride among many sources in order to coagulate it with FeSO4·H2O. After that the parameters influencing (concentration, pH, temperature) are studied to choose the best conditions for better reduction.

Defluoridation of drinkable water Comparative study and parameter influent

Atia D., Hoggui A., Abdelhafidh B. A.

International Letters of Chemistry, Physics and Astronomy

2013

Vol. 10, iss. 1

48-60

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.

Decreasing fluoride by coagulation in drinkable water from Souf region of Algeria

Atia D., Hoggui A.

International Letters of Chemistry, Physics and Astronomy

2013

Vol. 5

57-65

The drinkable water in Souf region at the south east of Algeria contains high quantity of fluoride which causes dental fluorosis. To reduce fluoride, we have chosen a sample with the biggest content of fluoride among many sources in order to coagulate it with Fe2(SO4)3źH2O. After that the parameters influencing (concentration, pH, temperature) are studied to choose the best conditions for better reduction.

Comparative study for the defluoridation of water by Coagulation

Atia D., Hoggui A., Abdelhafidh D. B. A.

International Letters of Chemistry, Physics and Astronomy

2013

Vol. 8, iss. 2

123-131

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.
