fluoridation and defluoridation of water

Download preview PDF. All these processes are very effective in removing fluoride ion, but the disposal of fluoride-containing sludge is problematic. By preventing cavities, community water fluoridation has been shown to save money both for families and for the US health care system. Besides, the major techniques we can use for defluoridation include adsorption, precipitation, ion exchange, membrane processes, etc. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. This consumption may reduce the effectiveness of a community fluoridation program. As with the treatment of other chemical contaminants, such as arsenic, fluoride cannot be removed by typical water treatment means. “Glass-half-full” By jenny downing – glass half-full (CC BY 2.0) via Commons Wikimedia This service is more advanced with JavaScript available, Advanced Physicochemical Treatment Processes Drinking fluoridated water keeps teeth strong and reduces cavities (also called tooth decay) by about 25% in children and adults. 1. Thus, it is important to know the exact difference between fluoridation and defluoridation. “Defluoridation.” Wikipedia, Wikimedia Foundation, 20 Sept. 2019, Available here. Fluoridated water operates on tooth surfaces: in the mouth, it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities. Part of Springer Nature. Groundwater accounts for 98 percent of the earth's potable water. Since excessive fluoride ion content in drinking water can cause different health issues, defluoridation is an important process. Further, this ion is present in high amounts in groundwater compared to surface water. Side by Side Comparison – Fluoridation vs Defluoridation in Tabular Form This is a preview of subscription content, B. Sprague, M. Bernhardt, and S. Barrett, “Fluoridation: Don’t let the poisonmongers scare you!”. Cite as. Unable to display preview. Summary, Fluoridation is the process of increasing the fluoride level in drinking water. Compare the Difference Between Similar Terms. The following infographic summarizes the difference between fluoridation and defluoridation. The key difference between fluoridation and defluoridation is that fluoridation is the process of increasing the fluoride content, whereas defluoridation is the process of decreasing the fluoride content in drinking water. The Project Defluoridation of Water aims to develop affordable technology to remove excess fluoride in drinking water for rural communities in India, where there is a dearth of access to even very basic resources, like proper nutrition, education, and clean drinking water. It has been reported that the cost of fluoridation of public water systems averages $0.54 per person annually (4).In recent years,water consumption from bottle water has increased;some of the water used for bottling has a suboptimal level of fluoride. Typically a fluoridated compound is added to Both fluoridation and defluoridation are very important processes regarding the quality control of municipal water we use as drinking water. © 2020 Springer Nature Switzerland AG. It is due to the leaching of minerals. However, fluoridation does not change the colour, smell or taste of water, Figure 01: Fluoridation does not Change the Colour, Smell or Taste of Water. The key difference between fluoridation and defluoridation is that fluoridation is the process of increasing the fluoride content, whereas defluoridation is the process of decreasing the fluoride content in drinking water. The World Health Organizationhas recommended a guideline value of 1.5 mg/L as the concentration above … Not logged in These keywords were added by machine and not by the authors. In this process, a chemical compound containing fluoride ions is added to drinking water. This consumption may reduce the effectiveness of a community fluoridation program. 2. pp 293-315 | “Dental fluorosis (mild)” By Matthew Ferguson 57 – Own work (CC BY-SA 4.0) via Commons Wikimedia. 74.208.166.204. Worldwide, fluoride is one of the most abundant anions present in groundwater. It is the controlled adjustment of the fluoride level to maintain the appropriate fluoride levels in the water. Defluoridation is the opposite process of fluoridation. Another compound we can use for fluoridation is sodium fluorosilicate. Both fluoridation and defluoridation are very important water-treating processes. Defluoridation is a process used on a large scale to maintain the levels of fluoride in drinking water. 4. Not affiliated 3. Defluoridation is the downward adjustment of the level of fluoride in drinking water. The process of increasing or adding the trace element fluorine into drinking water in its ionic form as fluoride for the prevention of dental caries (tooth decay)is known as water fluoridation,whereas water defluoridation is the lowering of the naturally occurring fluoride level in drinking water to prevent dental fluorosis or the browning (mottling) of teeth (2).In 2001,US Surgeon General David Satcher stated: “Water fluoridation continues to be a highly cost-effective strategy,even in areas where the overall caries level has declined and the cost of implementing water fluoridation has increased” (3). 1. 2. Sometimes, these processes may release even contaminants to the water. Difference Between Tetrahedral and Octahedral Voids, Difference Between Potassium Iodide and Potassium Iodate, Difference Between Polyvalent Element and Polyatomic Ion, Side by Side Comparison – Fluoridation vs Defluoridation in Tabular Form, Difference Between Coronavirus and Cold Symptoms, Difference Between Coronavirus and Influenza, Difference Between Coronavirus and Covid 19, Difference Between Transactional Marketing and Relationship Marketing, Difference Between Meditation and Contemplation, Difference Between Interstitial and Appositional Growth, Difference Between Methylacetylene and Acetylene, Difference Between Nicotinamide and Nicotinamide Riboside, Difference Between Bleaching Action of SO2 and Cl2, Difference Between Collagen Elastin and Reticular Fibers. Defluoridation was first attempted in the 20 th century using an aluminum and sand filter. Earlier, people used sodium fluoride for this purpose. It is described as the downward adjustment of the level of fluoride in drinking water. Defluoridation is the opposite process of fluoridation. It has been reported that the cost of fluoridation of public water systems averages $0.54 per person annually (4).In recent years,water consumption from bottle water has increased;some of the water used for bottling has a suboptimal level of fluoride. Fluorine is the 13th most abundant element, and it is naturally introduced into the environment in both water and air(1).As a result, fluorine is present in small yet varying amounts in almost all soils, water supplies, plants, and animals. The health problems that occur due this high levels of fluoride include dental fluorosis and skeletal fluorosis. 2. The key difference between fluoridation and defluoridation is that fluoridation is the process of increasing the fluoride content, whereas defluoridation is the process of decreasing the fluoride content in drinking water. What is Defluoridation Boiling, UV treatment, most methods of filtration, and most chemical treatment options do nothing to remove fluoride concentrations from water. Defluoridation is the opposite process of fluoridation, and both these processes can be helpful in different situations. Fluoride is more present in groundwater than surface water mainly due to the leaching of minerals. This process was used to remove fluoride from the water. Although there are different techniques for defluoridation, there are a few limitations as well. So, even though there may be some advantages of fluoride in drinking water, there exists a lot of disadvantages as well and thus there must be some steps taken to remove fluoride from your drinking water via various filtration methods such as distillation, reverse osmosis, alumina defluoridation, etc; which can help you get rid of most unwanted impurities. In groundwater, fluoride ion is very abundant. However, it is an expensive chemical compound. This process is experimental and the keywords may be updated as the learning algorithm improves. The highest concentration of fluorine is found in our bones and teeth. The fluoride in water can prevent the formation of tooth cavities. An excess of fluoride in drinking water causes dental fluorosis and skeletal fluorosis. “Water Fluoridation.” Wikipedia, Wikimedia Foundation, 19 Sept. 2019, Available here. Defluoridation is the process of decreasing the fluoride level in drinking water. Today, the compound USA uses for this process is fluorosilicic acid, which is inexpensive.
