Removal of Fluoride and Nitrate from Drinking Water by Low-Cost Adsorbents

Abstract Contamination of drinking water by fluoride and nitrate has become a serious environmental and public
Contamination of drinking water by fluoride and nitrate has emerged as a major environmental and public health issue, particularly in rural and semi-urban areas. Excessive fluoride concentration in water can cause dental and skeletal fluorosis, while elevated nitrate levels may lead to serious health problems such as methemoglobinemia and other water-borne diseases. The present study focuses on the removal of fluoride and nitrate from drinking water using low-cost adsorbents as an economical, efficient, and sustainable treatment method. Various locally available adsorbent materials, including activated carbon, agricultural waste-based media, and natural minerals, were investigated for their adsorption efficiency. The study was carried out under different operating conditions such as pH, contact time, adsorbent dosage, and initial contaminant concentration to determine the optimum treatment conditions. The effectiveness of the adsorbents was evaluated in terms of percentage removal and adsorption capacity. Experimental results showed a considerable reduction in fluoride and nitrate concentrations, indicating that low-cost adsorbents can serve as a promising alternative to conventional water treatment technologies. This approach is especially beneficial for resource-limited regions due to its affordability, ease of availability, and sustainability. The study concludes that the use of economical adsorbent materials is a feasible and practical solution for providing safe drinking water.
