Removal Of Fluoride From Water And Waste Water By Using Low Cost Adsorbents

India is among 23 nations where in a large population suffers from dental and skeletal flourosis due to high fluoride concentration in ground water. The prominent states, which are severely affected, are Andhrapradesh, Rajasthan, Gujarat, Uttar Pradesh and Tamil Nadu. Fluoride beyond desirable amounts (0.6 to 1.5 mg/l) in ground water is a major problem in many parts of the world. Taking the severity of the problem into consideration, the present study is carried out to study on effective and cheap adsorbents for the removal of fluoride from the water. Batch adsorption studies are carried out. Batch adsorption studies demonstrate that the adsorbents have the significant capacity to adsorb the Fluoride from water. The experiments were carried out in laboratory on certain low cost adsorbents like concrete, ragi seed powder, Red soil, horse gram seed powder, orange peel powder, chalk powder, pineapple peel powder and multhani matti.
