Removal of Iron and Fluoride by MSC Adsorbent from Ground Water

The problems related to groundwater contamination by iron and fluoride is common and serious all over the world, especially in developing countries. Excess amounts of these contaminants have created health problems. For this reason, the maximum permissible limit for iron given by WHO and BIS is 1 mg/l, however 0.3 mg/l is the desirable limit. For fluoride, the desirable limit as per WHO is 0.5-1 mg/l. While as per EPA and PHS the optimal levels of Iron and Fluoride in drinking water is 0.3 mg/l and 0.7 mg/l respectively. In this study, an effort has been made to remove iron and fluoride from groundwater using the process of adsorption. The experiments were performed on various parameters like dosage of adsorbent, pH, temperature and contact time to check their influence on adsorption. Adsorbent dosage of 4.7 g/50 ml at pH 5, temperature of 20ºC and contact time of 420 minutes were considered as optimum.
