Modified Crushed Oyster Shells for Fluoride Removal from Water
Oyster shells are a rich source of calcium carbonate 10,11,12 that can be used for fluoride removal 13. Calcium carbonate can be used to produce hydroxyapatite which has been shown to be effective for fluoride removal from water 14. Phosphoric acid–enhanced limestone has improved fluoride removal efficiency and is a low-cost material 15. In ...

Fluoride removal from water using crushed limestone
An examination of defluoridation by industrial grade limestone indicated that a combination of precipitation and adsorption of fluoride can be more effective for defluoridation of water. Pre-acidified fluoride water using two edible acids, viz., acetic acid (AA) and citric acid (CA) have been used for treatment by crushed limestone of diameter 3-4 mm to precipitate fluoride as CaF 2 in ...

Impact of Phosphate on Fluoride Removal by Calcite
Abstract Fluoride can be removed from wastewater by addition of calcite. However, fluoride is often found in complex mixtures where other contaminants can affect the removal process. Batch experiments were used to determine the impact of phosphate (PO43−) on the removal of fluoride from solution by calcite. In the experiments, up to 2,000 mg/L F− and 500 …
