Recently I visited CSIR technofest 2010 showcased by Council of Scientific & Industrial Research, New Delhi, at India International Trade Fair in New Delhi, the Capital of India. In this technofest, I have seen a technology as a lay man to understand about what is "Domestic Fluoride Removal Unit" which was developed by NEERI (National Environmental Engineering Research Institute), Nagpur.
What I understood that the invention was - Calcium salt and Phosphorous salt will be mixed in the water and then filter through sand for reducing fluoride content. This is domestic technology and many areas in many states of India are having the fluoride problem in the water. This fluoride content affects the legs and other parts of the body of humans. Many governments were blamed by many civic bodies not taking care of problems of people and there is no implementation of schemes or programs to reduce the fluoride content of drinking water. Many people affected and their legs were damaged by bending in different shapes and they are not able to walk due to this fluoride content in the water.
The NEERI, Nagpur under the aegis of CSIR, New Delhi has developed this technology for commercialization for domestic use to reduce the fluoride content in the house itself. The process involves formation of insoluble fluoride complex with salts of calcium and phosphorous, and filtration through the sand filter to reduce the fluoride concentration in water to <1 mg per liter and is suitable for the water upto fluoride concentration of 10mg/L.
NEERI, Nagpur has installed 60 demonstration units at Shankara Village in Maharashtra, India. This technology is domestic one and it is required by every house who are affected out of this fluoride content water.
Technical details, specifications and full details of technology and its commercialization details will be available with the NEERI, Nagpur. Those who are interested in this technology all over the world can contact this laboratory and reduce the fluoride content in the water for saving human mankind.
Below are useful links to enquire about the above technology
