What is a common method to reduce fluoride levels in drinking water?

• A. Distillation
• B. Filtration
• C. Chemical adding
• D. Simple boiling

Answer: (B)

Filtration is a common method to reduce fluoride levels in drinking water effectively. There are specific filtration systems designed to remove fluoride, such as activated alumina and reverse osmosis filters. Activated alumina works by adsorbing fluoride ions from the water, while reverse osmosis uses a semi-permeable membrane to reject fluoride along with other impurities. This method can significantly lower fluoride concentration, making the drinking water safer for consumption. The other methods mentioned have their limitations regarding fluoride removal. Distillation can reduce fluoride levels but may not be the most efficient or practical in all situations, as it requires a significant amount of energy and time to distill water. Chemical addition typically pertains to processes for enhancing water quality, but may not specifically target fluoride removal without creating other chemical interactions. Simple boiling does not effectively remove fluoride, as the fluoride ions remain in the water even after the boiling process, making it an inadequate method for reduction. Thus, filtration stands out as the most reliable and practical method for effectively lowering fluoride concentrations in drinking water.
