Comparative Analysis On Groundwater and Defluoridation Using Natural Adsorbents

Abstract

Fluoride is the one of the very few chemicals that has been shown to cause significant effect in people through drinking water which is found in excess in surface or ground water because of geochemical reactions are authropogenic activities various methodology used for defluoridation of water such as coagulation, precipitation membrane processes, electrolysis treatment, ion exchange process among these methods adsorption widely used because of cost effectiveness simplicity of design and operation. An attempt is made in this study with special reference to different natural absorbent such as ACTIVATED CHARCOAL, FlyASH, WOODEN ASH, RIVER SAND for defluoridation. The result obtained for these studies are the ash absorbent showed maximum adsorption significant reduction in turbidity, ph hardness, chloride, dissolved oxygen and fluoride with in the standard limit.
