Article 4 of Directive 80/777/EEC lays down the mandatory requirements applicable to each removal treatment that operators can put in place: It complies with the conditions of use which have been adopted by the Commission (so-called “EU approval”), following EFSA consultation (Article 4.1b and 4.1c); It does not alter the composition of the water as regards the “essential constituents” (Article 4.1); It may not be subject of any addition other than the introduction or re- introduction of carbon dioxide (Article 4.2), It does not lead to any disinfection action (Article 4.3). Sodium is the other. In some cases levels between 100 and 200 microg/l were reported. It is used as a desiccant for drying gases and air and as a fluoride filter for drinking water. In any case the release of impurities during the treatment from the activated alumina into the NMW shall not result in concentrations exceeding the limits set in Commission Directive 2003/40/EC  or in the absence of limits in that Directive the restrictions set in Council Directive 98/83/EC of 3 November 1998 on the quality of water intended for human consumption  or in national applicable legislation. Aluminium is an atom. The modalities of this treatment are similar to those for regeneration. Some filters may … Ongoing levels above 4 mg/L can result in serious health problems. Although most communities have problems persuading people to add fluoride to drinking water supplies, some natural waters have too high a fluoride concentration. Alumina is safe and does not add aluminum, but this does not mean it doesn’t have its share of drawbacks. In addition any biofilm possibly formed is also removed during this treatment. Like the name implies, Bone Char is actually the remains of animal bones that have been crushed, exposed to high furnace temperatures and carbonised. The Home Master Jr. Elite is a compact sinktop filter effective in removing fluoride and other contaminants from the drinking water supply. We're reprinting the document below in its entirety to address the issue. What do they do to the heart? European Standard EN 12902 of November 2004: Products used for treatment of water intended for human consumption. The fluoride removal process is based on adsorption on the surface of the activated alumina. If you search on the terms "fluoride removal" at the US Environmental Protection Agency site, you will find several articles on removing fluoride. ...activated carbon, activated alumina, silica gel, and molecular sieves. Fluoride removal, activated alumina, natural mineral waters. If it did, activated alumina would not have been certified to release nothing harmful into the water. Pesticides causing Heart Disease.. and more…. China 6-8mm Activated Alumina for Drinking Water Filters, Find details about China Defluorinating Agent, Water Filter from 6-8mm Activated Alumina for Drinking Water Filters - Shandong Avant New Material Technology Co., Ltd. The Scientific Panel on food additives, flavourings, processing aids and materials in contact with food wishes to thank Rinus Rijk for assistance in preparing the draft opinion for its consideration. The difference between an atom and a molecule. Due to presence of high fluoride … Why I kept to the Alkaline Diet for the last 20 years. The Cost of UltraStream filter replacement. In the text below, we've highlighted in blue some of the more significant items. Leaching of aluminium from the activated alumina depends on the pH of the NMW and the alumina manufacturing process . This purpose of this alumina water filter is for fluoride removal, however it can also reduce and remove arsenic and selenium from your water. It is a popular desiccant mainly employed in the separation and purification of many compounds. Granular activated alumina is used for the removal of arsenic and fluoride from drinking water. Activated alumina (AA) is the only filter material specifically designed to remove fluoride and arsenic from water. Information concerning the source and treatment of activated alumina and the filtration process conditions was provided and showed that critical steps of the proposed process are the following: Testing of activated alumina filter according to the European standard applicable for leaching tests (EN 12902)  to ensure that no impurities are leached to the water in quantities that result in concentrations exceeding the limits set in Commission Directive 2003/40/EC on the constituents of natural mineral waters, or in the absence of relevant limits in that Directive, the restrictions set in Council Directive 98/83/EC on the quality of water intended for human consumption or in national applicable legislation. NMWs shall be “suitable” for human consumption at source, but do not have to comply with the maximum limits for constituents and residues applicable to drinking waters. It’s THE best we could find anywhere in the world, in line with all other filter media in our UltraStream. Hydrogen Peroxide: Activated alumina is a special adsorbent for hydrogen peroxide made by anthraquinonoid method. Sodium chloride is a molecule, bound together ionically so it isn’t poisonous. Although NMW sources must be protected from microbiological contamination, they may contain bacteria naturally present at the source. It has a very high surface-area-to-weight ratio, due to the many “tunnel like” pores that it has.”. Report of the Commission ad hoc working group on the technological assessment of natural mineral water treatments on the evaluation of treatment by aluminium oxide for the removal of fluoride from natural mineral waters and spring waters, dated 30-03-2006: http://ec.europa.eu/food/food/labellingnutrition/water/index_en.htm. It is a highly porous material which is used as a desiccant, absorber, and also as a filter for water. The production process includes calcination at 500°C, which at the same time removes all organic substances. However, based on data provided  by optimising the pH conditions and selection of the appropriate medium the aluminium release resulting from the process would normally not exceed 40-60 µg/l. China Drinking Water Defluorinate 2-3mm Activated Alumina for Water Purifying Agent, Find details about China Defluorinating Agent, Water Filter from Drinking Water Defluorinate 2-3mm Activated Alumina for Water Purifying Agent - Shandong Avant New Material Technology Co., Ltd. For example, some will point to activated alumina for fluoridation removal. Council Directive 98/83/EC of 3 November 1998 on the quality of water intended for human consumption, OJ L 330, 5.12.1998, p. 32. The reagents used for initialisation and regeneration have to comply with the relevant European standards relating to the purity of the chemical reagents used for drinking water treatment. Lab tests show a capacity of 11,000 ppm with effluent levels below 0.2 ppm from 10 ppm feed (98%). There is an additional bonus of also removing arsenic and lead. The activated alumina used for treatment of NMWs has to comply with the standard applicable for leaching tests (EN 12902). The aluminum oxide removes fluoride, arsenic, and selenium to make water suitable for drinking. These activated alumina defluoridation filter water are 95% pure and ideal for various industries. The high crush resistance, high porosity and very stable chemical and physical attributes of activated alumina make it one of the most important and useful elements in our high-tech society. Go here to see how we use Activated Alumina in the UltraStream. In every case I have seen of people attacking AA, their competing product hes been using a cheaper method.
