Matters on water fluoridation have been an ongoing controversy around the world. The method of adding fluoride to water to remove bacteria and prevent tooth decay is debated to result into a positive or negative effect. There are even studies that show and prove how fluoride in water can be harmful to human health. Some evidences connected the fluoridation of water to gastrointestinal problems, thyroid diseases, endocrine disorder, low fertility, arthritis and cancer. For this reason, there are known methods on how to remove fluoride from water:
* Reverse Osmosis – this method works by separating water from other components, or in this case, fluoride. This is an expensive method and requires professional help in installation and needs to be run by electricity.
* Water Distillation – this method of purification relies on evaporation. The water is heated to form steam and the inert compounds cannot be evaporated and are left behind. The steam from the evaporation then cools and condenses to form decontaminated water.
* Bone Char Carbon – this method uses Bone char which is a coarse material from carbonized animal bones. The bones are heated in high temperatures in a low-oxygen atmosphere in order to keep track and regulate the quality of the product’s absorption capacity like defluoridation of water. Even though this method can be done do-it-yourself style, there is a possibility of difficulty in obtaining numerous bones. It is also tough to attain the intensity of the heat level needed. It is recommended and more time and effort saver to purchase the material that make it yourself.
* Activated Alumina – this method uses activated alumina which is an inorganic element that is a product of dehydrating alumina hydroxide at high temperature. The element is highly absorbent and demonstrates remarkable surface area which results in higher absorbent capabilities. The element is also resilient to thermal shock and scratch and does not swell, shrink, soften or disintegrate when submerged in water. Alumina can both act as base and acid because of its amphoteric properties. This method, however, is comparably expensive and needs to be replaced frequently.
