Atmospheric Water
Generator
Did you know that clean, drinkable water can be generated from the air
around us? Learn about the innovative technology of atmospheric water
generators and how they can benefit individuals, communities, and the
planet.

4. Atmospheric water generators (AWGs) are innovative devices that extract moisture from the
air and convert it into clean drinking water. They offer a sustainable solution to the global
water crisis by providing a reliable source of safe and potable water, especially in areas with
limited access to traditional water sources.
Clean water is essential for human survival and plays a crucial role in maintaining public
health. However, millions of people around the world still lack access to clean drinking water,
leading to waterborne diseases and other health issues. The global water crisis is a pressing
issue that requires immediate attention and sustainable solutions.
By introducing atmospheric water generators as a sustainable solution, we can address the
challenges of water scarcity and contamination, ensuring a healthier and more sustainable
future for all.
Introduction
Sustainable Solution for Clean
Drinking Water

5. How Does It Work?
1 Condensation
As air passes through a cooling unit,
the moisture in the air is condensed
and collected.
2
Filtration
The collected water is passed through
a filtration system to remove impurities.
3 Storage and Dispensing
The clean water is stored and
dispensed for consumption or use.

7. Extracting Water Vapor
Atmospheric water generators extract water vapor from the
air using various technologies such as condensation,
desiccation, or adsorption. These technologies allow the
machines to draw in air and separate the water vapor from
other components in the air.
Converting to Liquid Water
Once the water vapor is extracted, it is converted into liquid
water through a process called condensation. The water vapor
is cooled, causing it to condense into liquid form. This liquid
water is then collected and stored for use.
How Does It Work?

8. WORKING PRINCIPLE
1. COMPRESSOR:
2. CONDENSOR:
3. BATTERY:
An air compressor is a device that converts power (using an electric
motor, diesel or gasoline engine, etc.)into potential energy stored in
pressurized air (i.e., compressed air).
condenser is adevice or unit used to condense a substance from its
gaseous to its liquid state, by cooling it. In so doing, the latent heat
is given up by the substance, and will transfer to the condenser
coolant.
An electric battery is a device consisting of one or more
electrochemical cells with external connections provided to power
electrical devices.

9. Advantages and Benefits

10. Applications
Residential Use
Atmospheric water
generators are a
convenient and reliable
source of clean drinking
water for households.
Commercial Use
Atmospheric water
generators can provide a
sustainable source of water
for businesses and public
facilities.

emergency water supplies
in disaster-stricken areas
or for humanitarian relief
efforts.

11. Applications
1.Residential
Atmospheric water generators can be
installed in residential buildings to provide a
sustainable source of clean drinking water.
This is especially beneficial in areas with
limited access to clean water or unreliable
water supply. For example, in rural areas or
remote locations where traditional water
sources are scarce, atmospheric water
generators can provide a reliable and
independent water source for households.
Case Study:
In a small village in Africa, an atmospheric
water generator was installed in a
residential community. Previously, the
villagers had to walk long distances to fetch
water from a nearby river, which was often
contaminated. With the installation of the
atmospheric water generator, the villagers
now have access to clean drinking water
right in their own homes, improving their
health and quality of life.

12. 2.Commercial
Commercial buildings, such as offices,
hotels, and restaurants, can also benefit
from atmospheric water generators.
These generators can provide a
sustainable and cost-effective solution
for meeting the water needs of
employees, guests, and customers. By
producing water on-site, commercial
establishments can reduce their reliance
on bottled water and contribute to
environmental sustainability.
Case Study:
A hotel chain in a coastal city installed
atmospheric water generators in each of
its properties. This allowed the hotels to
provide guests with clean and safe
drinking water without the need for
plastic water bottles. The installation of
the atmospheric water generators not
only reduced the hotel's environmental
footprint but also saved costs associated
with purchasing and disposing of bottled
water.

13. 3.Industrial

be integrated into existing
infrastructure to ensure a continuous
supply of water, even in remote or
water-scarce locations. By using
atmospheric water generators,
industries can reduce their reliance
on traditional water sources and
minimize the environmental impact of
their operations.
Case Study:
A construction company working on a
project in a desert region installed
atmospheric water generators on-site.
This allowed the company to provide
its workers with a reliable source of
drinking water, as well as water for
various construction activities. By
using the atmospheric water
generators, the company reduced its
reliance on water deliveries and
minimized the environmental impact
of its operations

can provide a source of clean drinking
water when traditional water
infrastructure is damaged or
unavailable. By quickly producing water
from the air, atmospheric water
generators can help meet the
immediate needs of affected
communities and support relief efforts.
Case Study:
In the aftermath of a devastating
earthquake, an atmospheric water
generator was deployed to a temporary
relief camp. The generator provided
clean drinking water to the displaced
residents, who had limited access to
safe water sources. The atmospheric
water generator played a crucial role in
ensuring the health and well-being of
the affected population during the
emergency response.

15. Environmental Impact
Reducing Reliance on Traditional Water Sources
Atmospheric water generators provide a sustainable solution by
extracting moisture from the air, reducing the need for traditional
water sources such as rivers, lakes, and underground aquifers.
