Scientists Discover New Technique to Remove Fluoride from Drinking Water

An image of water that is tainted with FluorideAROUND the world, it is estimated that tens of millions of people are affected by both dental and skeletal fluorosis. In many cases, it is the addition of fluoride into drinking water supplies by governments that is the primary cause of both dental and skeletal fluorosis.

Common techniques used for defluoridation are coagulation-precipitation, membrane process and ion exchange.

The problem with these three techniques is that they are either too expensive or they further pollute the water.

Researchers from the National University of Sciences and Technology in Pakistan have discovered an effective method to remove fluoride from drinking water that is less expensive than conventional filtration processes and is safe to use.

The study, published in the Journal of Chemistry, concluded that the removal of fluoride from drinking water using modified immobilized activated alumina (MIAA) resulted in a removal efficiency that was 1.35 times higher than normal immobilized activated alumina.

Modified immobilized activated alumina (MIAA) was added to water that was tainted with fluoride and then analysis was conducted to evaluate the quantity of fluoride that was removed from the water.

Effect of an adsorbent dose on the removal of fluoride

It was discovered that MIAA, at 20 +/- degrees celsius has the capacity to remove more than 95% of fluoride from water. In fact, the adsorption capacity of MIAA was much higher (0.76 mg/g) when compared to the adsorption capacity of activated charcoal (0.47 mg/g) for the same concentration fluoride samples.

The adsorption method that is used by modified immobilized activated alumina (MIAA) is much more cost-effective (Ali, I., & Gupta, V. K. (2007) Advances in water treatment by adsorption technology. Nature Protocols) than the popular Reverse Osmosis Filtration method.

Considering that both MIAA and Reverse Osmosis Filtration remove more than 90% of fluoride, MIAA could be a viable alternative to removing fluoride from drinking water supplies in developing countries.

Unfortunately, there are some limitations to the use of MIAA in removing fluoride from drinking water. The greatest challenge in the use of MIAA for removing fluoride from drinking water is filtering MIAA once all fluoride has been absorbed.

However, considering that the granules produced by MIAA varied from 3 to 6 mm, all that was required during the study to remove the MIAA granules from the water was basic water filtration.

Ultimately, the primary challenge faced when trying to removing fluoride from drinking water is cost.

The use of modified immobilized activated alumina (MIAA) to remove fluoride from drinking water could become a viable option that would enable communities in both developed and developing nations to remove fluoride from drinking water.

    At best only 95% of fluoride can be removed by any filter-pass process. When fluoride compound molecules are smaller than water molecules, holding these (nano-particulates) fluoride compounds in a very fine filter will also hold the larger water molecules, resulting in no water flow at all. Fifty years ago wheat grass was discovered to absorb fluoride in water. Young wheat grass is stirred around in a bucket of water and left for some hours to remove all fluoride from the water. There are some videos on YouTube concerning this. There are instruments to test water for fluoride, so testing can be done. The problem with fluoridated water is this so-called ‘fluoride’ is a highly toxic industrial waste by-product inherent with particulates of Uranium-238 and Polonium-210 (and more) so now we have alpha-particle radiation to be filtered out, or we ingest these highly toxic radioactive particulates and most people will acquire cancer in due course … twenty, thirty, forty years on. One speck of ingested Plutonium is certain to cause death by cancer in anyone. The cause of death will be announced as cancer, and fluoridation by-products will not be looked for or mentioned. In fact fluoride is never mentioned on any food and beverage ingredients labels!? The effects of fluoridation have been researched, documented and likened to smoking … both quiet killers. Do your own research now and start your journey of enlightenment by Google searching Dr Paul Connett who has compiled a book full of research results from specific fluoride research scientists. Fourteen Nobel Prize Laureates in Chemistry and Medicine are on record to being opposed to fluoridation, which is also detailed on the internet. Yet there are numerous ‘dentists’ and ‘doctors’ who ‘know better’ … supremely arrogantly so!
