However, the total “functional household tap connection (FHTC)” is currently less than thirty percent across the state. Additionally, all the commercially available fluoride water filters are expensive and complex to manufacture. Therefore, the present thesis looks into designing a low-cost, low-energy fluoride water filter for the large number of low-income households in Rajasthan. A thorough literature survey indicates that many natural rocks and their derivatives show strong adsorption of fluoride, and Rajasthan happens to be one of the largest producers of these rocks in India. A survey of the commercially available and patented ceramic filters in Latin America, Africa, and South-East Asia shows that adsorption-based, rock-made ceramic filters can be a potential solution to the fluoride problem. Therefore, the current research work plans to evaluate the adsorption capacity and kinematics of a phosphate system incorporated clay adsorbent (a mixture of kaolinite, phosphorite, gypsum, and bauxite) and a novel adsorbent named wollastonite for this purpose. These objectives are planned to be achieved through a series of physico-chemical and surface property analyses, and adsorption experiments through batch tests and column experiments.
