This will convert humidity present in the air into the water.It works on principle of condensation,Now, this technology is practically implemented at industrial level.Instead of some traditional techniques for same work.

James J Reidy discovered the concept behind the
technology 20 years ago.
In 1998 research and development began and in 2002 Air to
Water Technology was integrated.
Atmospheric water generator (AWG) is a electricity-powered
device that uses the dehumidification principle to make pure
drinking water out of the moisture present in the air.
From centuries, many people worldwide devised different
methods to produce drinking water.
Many forget the fact that sufficient water is readily available in
the air due to atmospheric water cycle that can be tapped
As the working principle of AWG is based on the
Dehumidifier to extract water from moist air.
A dehumidifier sucks in air from one end, takes the
moisture out of it, and then blows it back out again. The
moisture drips through into a collection tank.
Similarly, water vapor in the air is condensed by cooling
the air below its dew point, exposing the air
to desiccants, or pressurizing the air in AWG.
Primary Techniques Used
In this type, a compressor circulates refrigerant through a
condenser and then surrounding air is cooled by an
A controlled-speed fan pushes filtered air over the coil.
This lowers the air temperature to its dew point, causing
water to condense.
The resulting water is then passed into a holding tank with
purification and filtration system to keep the water pure.
It reduces the risk posed by viruses and bacteria which
may be collected from the ambient air on the evaporator coil
by the condensing water.
to cool the
This method uses a solution of chemical salts to pull water
out of the air. Salt is a natural desiccant, which means that it
draws and holds moisture.
The technology may use liquid or solid desiccants to pull
water from the air (like Lithium bromide, Silica gel).
In desiccant based water generators, humid air passes over
a salt mixture. The wet salt is then heated to the boiling point.
The steam is condensed and routed to filters for processing.
The resulting water is clean and free of chemicals. This is
mostly applied in large-scale levels like the military or
Clean and pure can be obtained due to processes
of multi filtration.
Eliminates hazards caused by viruses, bacteria,
pesticides and heavy metal contaminants.
Rich oxygen contained in the water improves
metabolism of your body.
Tastes sweeter and better.

Pure water production in industries
Self-filling water bottle harvests clean drinking water
from the air.
Today’s steel pipes will soon be replaced with
tomorrow’s air pipes where there is shortage of water.
Despite widespread water pollution and shortages of
drinking water, there is an abundance of water around us –
from the air that we breathe it doesn’t matter where you are –
even in the desert.
Several water treatment methods exist to tap these sources,
from traditional methods to modern techniques .
Water harvesting and treatment technologies that are solar
or wind powered is the most environmentally friendly way to
extract pure quality water from the air or sea at a low cost.
The excellent information is that these technologies are now
