Technology for Fluoride Remediation from Water (TFRW) [Available for transfer other than Madhya Pradesh (India)]

In India 62 million people including 6 million children are estimated to have serious health problems (dental and skeletal fluorosis) due to consumption of fluoride contaminated water. As per Indian standard IS10500 for drinking water, the maximum permissible concentration of fluoride in drinking water is 1 ppm (mg/L). The existing methods for remediation of fluoride are based on alum (Nalgonda process), activated alumina and electrolytic defluoridisation. In these processes the problem is presence of residual aluminum, generation of waste and need for electricity. 
To overcome these difficulties, by using this technology the concentration of fluoride reduces to safer level (~1 ppm) even from as high as 20 ppm level. The treated water quality is well below the drinking water limits set by IS 10500. The method is rugged and works well, irrespective of pH and TDS of water. Sodium fluoride is by product which can be used in pharmaceutical formulation for treatment of tooth cavity. The fluoride removal by this technology is low cost & suitable for operation in remote areas as no electricity is needed. 

India is one of the worst fluorosis affected countries, with large number of people suffering. This is because a large number of Indians rely on groundwater for drinking purposes and water at many places is rich in fluoride. In India 62 million people including 6 million children are estimated to have serious health problems (dental and skeletal fluorosis) due to consumption of fluoride contaminated water. As per Indian standard IS10500 for drinking water, the maximum permissible concentration of fluoride in drinking water is 1 mg/L.

This fluoride remediation technology for ground water is low cost, simple regeneration (adjusting pH of adsorbent), adsorbent can be regenerated for any number of times, no loss of water in remediation process, regenerate solution can be reused for any number of times and its volume (initially 5 % of volume of remediated water) is decreases with increasing the cycle of regeneration (after 10 cycle ~ 2%), adorbent?s capacity factor (~15 mg/g of adsorbent) remains same even at very high TDS (>1000) of water and with any number of regeneration, no significant change in pH (± 0.3) and TDS (± 40) of raw and treated water, no residual adsorbent(<10 ppb) in the treated water, no consumption of electricity and no waste generated.

SALIENT FEATURES

  • No waste generated
  • Low cost and simple regeneration
  • Adsorbent can be regenerated for a number of times
  • No loss of water in remediation process
  • High capacity factor (15 mg/g)

Fluoride is known to occur at elevated concentrations in a number of parts of the world and in such circumstances can have, and often has, a significant adverse impact on public health and well-being. India is one of the worst fluorosis affected countries, with large number of people suffering. This is because a large number of Indians rely on groundwater for drinking purposes and water at many places is rich in fluoride. In India 62 million people including 6 million children are estimated to have serious health problems (dental and skeletal fluorosis) due to consumption of fluoride contaminated water. As per Indian standard IS10500 for drinking water, the maximum permissible concentration of fluoride in drinking water is 1 mg/L. 
A fluoride remediation technology is needed which should satisfy the main following criteria:
1. Low cost. 
2. No use of electricity. 
3. Adsorbent used for remediation should be reusable. 
4. No waste generation. 
The main objective of this work is to develop a fluoride remediation technology which satisfies the above mentioned parameters.


This fluoride remediation technology for ground water is low cost, simple regeneration (adjusting pH of adsorbent), adsorbent can be regenerated for any number of times, no loss of water in remediation process, regenerate solution can be reused for any number of times and its volume (initially 5 % of volume of remediated water) is decreases with increasing the cycle of regeneration (after 10 cycle ~ 2%), adorbent?s capacity factor (~15 mg/g of adsorbent) remains same even at very high TDS (>1000) of water and with any number of regeneration, no significant change in pH (± 0.3) and TDS (± 40) of raw and treated water, no residual adsorbent(<10 ppb) in the treated water, no consumption of electricity and no waste generated.

ADVANTAGES

  • No consumption of electricity
  • No waste generated
  • Low cost and simple regeneration
  • Adsorbent can be regenerated for a number of times
  • No loss of water in remediation process
  • High capacity factor (15 mg/g)
