REMOVAL OF FLUORIDE FROM DRINKING WATER BY USING LOW COST ADSORBENT

Abstract

Millions of people rely on drinking water that contains excess fluoride. In fluoride endemic areas, especially small communities with staggered habitat, defluoridation of potable water supply is still a problem. In this study, adsorption potential of granular activated carbon (GAC) from charcoal and coconut shell is investigated for defluoridation of drinking water using continuous fixed bed column. The influence of various operative parameters such as concentration of fluoride, bed height, flow rate, and adsorption capacity of both the adsorbent is carried out.The fluoride removal from synthetic sample is found up to 72% for fluoride ion concentration of 4mg/L.
