International Centre for Clean Water

• Every problem is dwarfed in front of the giant water crisis looming large on

the planet.

• Water stress – in quantity and quality- is felt most severely by the

populous countries.

• Indian subcontinent is at the centre of action.

• Hence this centre – Finding solutions for clean water for a sustainable

future, collectively.

Prof. T. Pradeep pradeep@iitm.ac.in

Objectives of the new centre

Water incubation hub Development of an integrated water technology business incubator for the benefit of everyone – ready to

translate any water technology solution, with IP protection

Affordable solution for fluoride-free drinking water

Creation of affordable technologies for fluoride removal using advanced nanomaterials – a solution that cost only in the range of 5-10 paise per litre of pure water, delivered at homes

Sensors for water quality

Development of integrated sensor-arrays for remote monitoring of water quality (and quantity)

Sustainable atmospheric water capture units

Development of solar power driven high efficiency atmospheric humidity capture devices using nanotechnology for production of clean drinking water

Desalination units using new technologies

Water desalination using capacitive desalination (CDI)- low energy desalination units using advanced nanostructures

Geo-specific water purifier bottles

Clean water solutions during natural calamities

Training tomorrow’s water professionals

Ensuring sustainable growth of the centre and the country

Create and Translate Nanotechnology to Society in the context of clean water

AMRIT Inline Domestic Unit

• No energy required, runs with gravity pressure.

• Unit has feed inlet, backwash outlet and pure

water outlet( opens in pure water reservoir).

• Feed inlet need to be connected to home water

line to get pure water and backwash outlet to

drain.

• Cartridges can be backwashed by sliding nob from

right to left.

Placed on Wall Inside View

• Unit has pure water reservoir of 4.5 liters volume.

• Once pure water reservoir is filled, feed line will shutoff automatically and will

open again after 1 liter pure water collection by user.
