摘要

Fluoride is one of the major issues globally due to the health issues associated with it. In the present study, the authors tried to develop an indigenous fluoride removal filter and further tried to remove fluorine from high fluoride-containing water from the Shekhawati regions of Rajasthan. Fluorosis and methemoglobinemia are among the disorders prevalent in these places. Here, firstly, water samples from the Shekhawati region in Rajasthan were collected and tested for various water parameters, including water hardness and fluoride. Further, an indigenous innovative and economical filter was fabricated based on the results obtained from the water analysis. The designed water filter has three distinct filtration chambers strategically integrated to uphold fluoride concentrations within the acceptable range of potability without electricity. The incorporation of activated alumina, activated charcoal, and sand (>63 µm, 50 gm) in the three filtration chambers impart a heightened fluoride sorption capacity. Additionally, the inclusion of silt (<63 µm, 60 gm) and sodium hypochlorite (4%) contributes to the removal of foul odors caused by bacterial contamination. The filtration capacity of the designed filter was about 1 liter of water within a span of 4 hours, which could achieve a 96% fluorine removal efficiency from the fluoridated water. The filtration process is efficient, maintaining fluoride levels below the WHO guideline of 1.5 mg/L, thus preventing dental and skeletal fluorosis. The device is effective across varying initial fluoride concentrations in the various parts of the Shekawati region, demonstrating its reliability in diverse locations. It could play a major role in reducing the health issues arising due to fluorine not from India but also globally in the future.
