2. Flouride
1. Fluorine is the ninth element of the periodic table.
2. Nevertheless, its applications and biological significances were
known only in the decades of 1920’s. It is the lightest member of the
halogen family.
3. Most electronegative among all chemical elements .
4. Fluorine has both notable chemical qualities and physiological
properties.
5. which are of great interest and significance to human health.
6. Fluorine is rarely or never found free in the nature in elemental
form.
7. It has strong affinity to combine chemically with other elements to
form compounds called ‘fluoride’.
3. Fluorine always occurs in combined form of minerals
as fluoride.
It is high reactivity and represents about 0.06 to
0.09% of the earth crust The presence of fluorine in
ground water is mainly a natural phenomenon, and
mainly influenced by local and regional geological
conditions, as the fluoride minerals are nearly
insoluble in water.
fluorine is present in ground water only when the
conditions favor their solution.
SOURCE OF FLUORIDE IN WATER:
4. Fluoridesorb (FS), a filter media consisting of
Fe(O)OH, was investigated for removal of
fluoride ion (F) from water.
Adsorption was studied in batch experiments
at room temperature together with the effect
of contact.

WATER
5. Category A: 50% and above villages have excess of
fluoride (very serious).
Category B: 25-50 % villages having excess fluoride.
(serious).
Category C: 10-25 % villages having excess fluoride
(less serious).
Category D: Below 10% villages having excess fluoride
(insignificant).

9. Flouride effected Water passes through
Fluoridesorb media and get adsorb and water
will be ready to use.
It is adsorption media with porosity on surface
having more surface area than any other
media available.
Process of operation
10. •Online fluoride removal
•No maintenance
•No water waste
•Up to 7 ppm fluoride removal
•3 – 4 years of self life of media
•Environmental friendly
•High adsorption capacity
•By product as heavy metals removal
