New low cost defluoridation
technology: KRASS Defluoridation Process (Under Patent):
Systemic Fluorosis
is an endemic problem in several developing countries.
In India, 17 states are endemic for Fluorosis,
5 of which have indicated hyperendemicity for Fluorosis
in all districts. WHO standards permit only 1.5 mg/l as
a safe limit for human consumption. People in several
districts of Rajasthan are forced to consume water with
fluoride concentrations of up to 44-mg/l that has resulted
in permanent deformities, joint pains, general debility
and misery. About 60% of the fluoride intake is through
water- and considerable work on fluoride removal from
water has been done worldwide. However a safe, efficient,
and cost effective defluoridation technique/process that
leaves the treated water free from residual aluminum,
is not currently available. We have developed a defluoridation
process (KDP- Krass Defluoridation Process) that addresses
all these issues. In this process the fluoride contaminated
water is passed through a specially created filter to
get the defluoridated water.
This process is effective for unlimited
amount of fluoride concentration in the input water. Temperature,
pH, alkalinity and amount of dissolved solids in the input
water also do not affect this process. Nor is it affected
by the ambient conditions like atmospheric temperature
and humidity. The importance of the process is that it
is easy and requires minimal involvement of technical
personnel, is harmless and is cost effective.
In this process, once the filters are placed
in between the water supply the outflow of the defluoridated
water is without further expenditure except recharging
the filter as its capacity. The exhausted filter can be
easily recharged again without replacing the material
for at least 40 cycles. As a product, the process achieves
better removal of suspended matter, betters clarity and
maintains taste of water. The treatment cost is about
0.6 - 0.8 paisa per liter ($ 0.001/gallon) at 10
ppm of influent fluoride.
This process differs from the known processes
in its simplicity, cost effectiveness and very low traces
of residual aluminum in outlet water. It is a practical
approach, especially for rural population around the world.
KDP has been featured in many technology
journals relating to Water treatments and has been mentioned
by renowned authors in their research. For more information
