Analysis of Ground Water Defluoridation by Adsorption Process

In India large population is mainly belong to rural areas which depend on ground water for their drinking purpose. The fluoride concentration in ground water varies from place to place. The data show that the fluoride distribution in ground water varies from 0.01mg/l to 48 mg/l [2] therefore it is require to observe defluoridation by cheap and easy method. Adsorption procedure is worth for its ease of operation, High productivity for fluoride removal and can remove up to 90% fluoride.. Adsorption procedures include the water’s entry through a contact bed where fluoride is removed by ion exchange or surface chemical reaction with the solid bed matrix. Adsorption technique is efficient and can remove ions over an extensive variety of pH to a lower leftover concentration than precipitation. This paper review about the defluoridation by a natural absorbent i.e. sugarcane bagasse which is cheap and effective and gives perfect removal of fluoride in drinking water upto 84%. Also paper present the information on occurrence of fluoride and its effects on human health and various control method for the removal of fluoride (specially sugar cane bagasse).
