Why Fluoride Removal ?
Excessive Fluoride in Water is a menace. The permissible limit in drinking water is 1.5 ppm in India where as it is much lower as per World Health Organization Standards.Excess Fluoride in Water can cause several diseases such as:
  • Dental Fluorosis
  • Skeletal Fluorosis - Arthritic pain, spine rigidity, malshaping of bones, etc. When you ingest Fluoride, only about 50 comes out and the remainder is stored in the bones, which accumulated over a period, causes severe physical problems.
  • Cancer
  • Genetic Damages
  • Fluoride is more toxic than lead and slightly less toxic than Arsenic.
What is Bio-F?
  • Bio-F is a biological adsorbent using natural shell as raw material
  • Porous in nature
  • Bio-F is insoluble in water
  • Bio-F has high temperature tolerance
  • Bio-F has the capability to remove Fluoride
  • Can remove Fluoride in excess of 90
  • Bio-F is highly cost-effective
  • Can be used without electricity
  • Suitable for domestic and community purpose
  • Regeneration produces no hazardous material
  • No Fluoride in waste water
  • Low contact time (3-5 minutes).

Why Bio-F?
  • Safe-No Chemical required!
  • High&steady adsorption
  • High fluoride removal efficiency
  • Stable regeneration capability
  • Cost effective
  • Tested&certified by various leading labs across the country
  • Safe, Simple regeneration.
Bio-F Regeneration Methods - Convenient Safe Simple
Convenient. Safe. Simple.
Regeneration Method 1 -
START. Keep the media dissolved in alum solution for 2-3 hours. Then drain the alum solution out and rinse with fresh water. STOP.
Regeneration Method 2 -
START. The new regeneration process developed by us, requires you to just insert hot water at > 70 degree C or pass steam through the media and then rinse with fresh water. STOP.

1. Defluoridation
capacity
1 mg/g
3-4 mg/g
2. Regeneration
Process
Regeneration by exposing to
4% caustic soda (hazardous
chemical) difficult to carry out
regeneration onsite. Must be
carried to regeneration centre.
Regeneration using
alum or hot water/
steam >70oC. Can be
easily carried out at site.
3. Wastewater
Wastewater contaminated
with Fluoride thus going
back to ground at the same
location.
No Fluoride in
wastewater.
4. Neutralization
Neutralization required with
sulphuric acid after regeneration
again hazardous chemical
use.
No neutralization
necessary.
5. Number of
Regenerations
Possible
3-4, after which media needs
replacement.
15-20 times
