Flouride Removal From ground water in Rajasthan, India
Hi Dear Leo,
The State of Rajathan, India also has very high fluoride contents in ground/well water. PHED, WSSO, Rajasthan is using Domestic Deflouridation Units and Hand Pump attached Deflouridation Units for removal of excess fluoride and providing community safe drinking water. These units are based on Activated Alumina (AA) technology which adsorbs the fluoride making water safe for drinking. AA can be rejuvenated in Acid-Alkali solution for reuse. Dilution of fluoride water will also lower its concentration. RO can be another solution but it waste lot of water.
However, there is need of increasing the ground water level through water conservation/ recharging methods for long term and sustainable solution for fluoride free water.
With kind regards

Dear............,
We are currently developing in-house the technology of DFU (Domestic Deflouridation Unit) fitted with Manual force lift Hand Pumps for removal of excess fluoride and providing community safe drinking water in a few villages.
These units are based on a combination of the basic bio-sand filter and use of Activated Alumina (AA) technology which adsorbs the fluoride, to make water safe for drinking purposes. AA regeneration will follow the already known processes.
We are yet in the process of optimizing our DFUs by calibrating the exact AA material size (range 0.475 to 2 mm size) and depth etc. of the filter bed, prior to declare establishing a most suited conventional filtering and AA used DFU........it shall take us some more time before we claim having done this.
