ABSTRACT

Fluoride is a chemical element which is present in environment. Standard fluoride content in drinkable water not be exceed than 1.5 mg F/L according to the World Health Organization (WHO).Excess amount of fluoride ingestion leads health issues. It is compulsory to remove extra amount of fluoride. For this reason, many method have been established for remove fluoride from water and waste water such as ion exchange, precipitation, Donnan dialysis & electro dialysis, adsorption, membrane process like reverse osmosis & nano filtration, coagulation etc. kalinite, bentonite, charfines, nirmali seed & lignite are the low cost materials used for removal of fluoride from water by batch adsorption. Keywords: fluoride, removal, water and wastewater, adsorption, membrane technology
