IPS News Agency "SENEGAL: A filtration technique nikken corporation fluorine and salt
DAKAR, March 14 (IPS) - Researchers at the University Cheikh Anta Diop of Dakar (UCAD), Senegal, come to develop a method for removing fluorine and salt water for consumption. nikken corporation
The process of removing salt and fluorine based on the technique of nano-filtration and is done with a machine that can run for eight hours a day, says Professor Courfia Diawara, team leader of researchers whose work has been developed by the American company to give Pall machine 'Pall Aria Pure'.
This machine, which runs on solar and electric, was presented to the public nikken corporation on 24 February 2011, at UCAD. It can, every day, separating 4000-7000 liters of water and fluorine nikken corporation salt that pollute the groundwater in the Groundnut Basin including Louga, nikken corporation Diourbel, Fatick, Kaolack, Kaffrine and Thies, Senegal.
"The machine

desalination and de-fluoridation is reliable, robust and easy to use," said IPS Diawara who teaches at the Graduate School Water quality and water uses (EDEQUE) nikken corporation at UCAD.
"The elimination of fluorine salt and nano-filtration technology is reliable and inexpensive. Technically, we can popularize, nikken corporation it is possible," says IPS Saliou Ngom, the direction of the management and planning of water resources, the Ministry of Planning and Sanitation.
Brackish nikken corporation water - which contains salt - is commonly consumed by 27 percent of the population of the Groundnut Basin, according to Diawara, who also teaches at the University of Ziguinchor in southern Senegal. nikken corporation
"In the Groundnut Basin, the fluoride content of drinking water for more than three milligrams per liter, with a variation of the fluorine content of a drill to another., And the salinity is greater than 2,000 milligrams per liter, while the World Health Organization (WHO) recommends a maximum of 1.5 milligrams of fluorine and 500 milligrams of salt per liter of water, "said Dr Saidou Nourou nikken corporation Diop, a member of the research team the EDEQUE.
"Fluoride

and salt gives the water a brackish nature, which makes it unfit for consumption. Due to these substances, water is unpleasant and harmful to health," said the dentist Malick Faye, of Faculty of Medicine, Pharmacy and Dentistry of UCAD, who collaborated with researchers.
"Many studies nikken corporation have risen more than 80 percent of people living in the Groundnut Basin are affected by fluorosis, with severity varying according to the residential area ... It is especially well water that contains the greatest amount fluorine, "said Dr. Faye.
'' However, the studies we have conducted in the Kaolack region have shown that children who grew up in the Groundnut Basin have developed some dental fluorosis, sometimes no fluorosis for some, and showed, in addition, some dental caries "Faye is, adding that everyone is not affected by the effect of fluorine and / or salt.
According to Faye, studies conducted in developed countries, and even in some African countries, have confirmed that the de-fluoridation of water and desalination result, after several years, a reduction of dental nikken corporation fluorosis . the new technology of nano-filtration "removes excess fluorine, while leaving other water ions that give it its quality," says Dr. Faye.
Coupled with solar energy, this technology could be used advantageously along the Senegal River in the north, to the benefit of the villages that have no access to drinking water, Diawara suggests. Technology can, with sufficient energy production, desalination and de-fluoridation 120,000 liters per day on the river, he said.
