Removal of Fluoride using Bioadsorbents

Water is scares and not readily available for everyone. As young children we have always learnt various ways to conserve water and thinking of it now it is required for all human chores and processes .It is required for both domestic as well as industrial purpose. But now days it is being infested with waste ranging from floating plastic waste to chemical waste and have turned our water bodies in a pool of poison. These water bodies contain a number of contaminants like aluminum, copper, lead, zinc, etc. Fluoride is one such contaminant present in the water. Fluoride may also be present in the effluent discharged by the various industries which when enters the water bodies increases the concentration of fluoride in the water bodies. Industries are considered as a major source of increase in the fluoride level of the water. There are many methods of treatment available for removal of flouroide. But due to many disadvantages as mentioned in this paper, other less tedious and economical methods like use of bioadsorbents like rice hisk, red mud, etc. are being used widely now a days.
