Fluoride removal from water using crushed limestone Semantic
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 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 addition to adsorption of fluoride on limestone.

Fluoride removal by induced crystallization using fluorapatite/calcite
Abstract. The removal of fluoride from water by induced crystallization using fluorapatite (FAP)/calcite seed crystals was investigated. Batch experiments were conducted to determine optimal operating parameters. The effect of FAP/calcite mass ratio of the seed crystals, initial seed crystal concentration, molar ratios of Ca 2+ :PO 43− :F −Fluoride contamination of groundwater, both anthropogenic and natural, is a major problem worldwide.
