Abstract

A method of removing fluoride from water is disclosed. The method comprises of adding lime to the water to precipitate phosphate, bromide, silicate, sulphate and /or metal hydroxides; removing the precipitate from the water, adding alum and a flocculent to the water obtained after removing the precipitate, to further precipitate fluoride and facilitate formation of flocs thereof. The method further comprises of passing the water with flocs through a water purification composition capable of removing flocs, the water purification composition comprising quartz particles having iron hydroxide and aluminum salt coated thereon, wherein the iron hydroxide and aluminum salt are formed in-situ by reacting an iron salt with aluminum hydroxide, the coated quartz particles heat stabilized by calcination and collecting water with reduced fluoride levels from the water purification composition.
