Replicating Nature
?
Times of India ( 17 March ) carried following news :
Union Water Resources Minister Nitin Gadkari said on Friday that the country would soon have potable
water from sea at five paise per litre.
Trials for conversion of sea water into potable water have started in
Tuticorin, Tamil Nadu, said the minister of River Development & Ganga Rejuvenation.
This is indeed, a very good news
Another good news in respect of making available ,
clean drinking water , was reported in
today’s Business Line . Read :
JanaJal water ATMs sell
250 ml of chilled water for ₹1, one litre
at ₹5 and 20
litres for ₹20
“We plan to use this
fund to expand its footprint and operations, which Agarwal said would touch
1,000 water ATMs by the end of 2018.
“In near future, we plan to install 1,500
water ATMs at railway stations and another 1,500 at other places,” Agarwal said.
By 2020, he said,
JanaJal will be supplying 1 billion litres of clean and safe drinking water,
contributing its bit to keep India healthy.

MY OBSERVATIONS
:
•
Most affordable water dispensing technology (compared to water cans, pouches,
bottles etc.)
• Technology based on clean energy
and environment-friendly techniques such as solar energy
• Operates on solar energy & electricity
Gravel Filter for suspended particles
Silica Filter for fine TSS in water
Active Carbon Filter for odour eradication
Twin sediment filter
Dual Stage RO filtration
I suppose , all of
these filtration technologies + occasional use of electricity, makes this water
100 times more expensive, as compared to what Shri Gadkariji
claims .
And of course , it
must depend upon raw water supply from Public Water Distribution Network
As against this , I
suppose , that Tuticorin plant would draw sea water and possibly use , Solar
Energy for distillation / evaporation , thereby eliminating energy cost .
And , since this
process copies the nature , there is no need for any kind of filtration
But its limitation
is that , the plant has to be very close to sea ! No good for hinterland !
Now comes the BEST
news !
Extracting absolutely
clean water ( anywhere , including in deserts ! ) out of thin air , using Solar
Energy !
No need for
electricity / filtration / water source ( sea or public water supply ) !
Earlier , I had
reported this in my following blog :
To know how this technology has
progressed in last one year , read :
Last year , while sending my blog , I had requested
Shri Devendra Fadnavisji to contact Prof Yaghi , requesting him to make
available this WATER HARVESTING technology

Dear Shri Gadkariji,
You are absolutely right when you say :
"Water is the biggest problem in India. Only if we manage to save
water, forest and animals we would be able to go ahead. It is directly linked
to our country and the society"
I urge you to
contact the following members of the enlarged MIT team
