2. AGENDA
• Did you know?
• Introduction
• Then & Now
• Atmospheric Water Generators (AWG)
• Working of AWG
• Applications of AWG
• Likely Scenarios
• Benefits of AWG
• Strengths of AWG
• Weaknesses of AWG
• Conclusion

3. DID YOU KNOW?
Having access to safe and sufficient water and sanitation are now
recognized as a basic human right.
Without food, human beings
can live for 14 days or more
Human body can only survive a
few days without water

4. DID YOU KNOW?
One billion people worldwide live without clean, safe drinking water
Two billion live without basic sanitation

5. So, how do you make sure they get pure drinking water that
satisfies all their basic needs at low environmental impact?

6. INTRODUCTION
Newer applications help us in getting pure drinking water at low
environmental impact.
•Atmospheric water harvesters
•Desalination of seawater
•Compact reverse osmosis to thermo-ionic flow innovators

8. THEN - FOG HARVESTING
However, it is not always suitable or practical, especially in dry and arid
areas. This is where more modern techniques can be considered.
Fog fences are used to collect water from the humidity in the
fog.
It uses a mesh material strung tightly on poles, supported by
gutter to collect droplets, fed into pipes, and then stored in
tanks.

9. NOW - ATMOSPHERIC WATER GENERATOR
An atmospheric water harvester or atmospheric
water generator (AWG) is a electricity-powered
device that uses the dehumidification principle to
make drinking water out of the moisture in the air.

10. ATMOSPHERIC WATER GENERATORS (AWG)
Produce more water in places with higher temperatures and
humid climates
Need air with its trapped moisture to generate water
Need electricity (which can be obtained from the main
power grid or solar panels, wind turbine)
Are sustainable, reliable, and produces potable water without
complicated installation

12. WORKING OF AWG

13. APPLICATIONS OF AWG
Restaurants, bars, hotels, where copious amounts of clean
water is required use AWG
Office environments that use bottled water units can do
away with plastics when replaced with AWG
Remote locations, island resorts, mining sites, and instances
where water scaling is an issue, use AWG

14. LIKELY SCENARIOS
• In such cases like, natural disasters and epidemics, the
availability of AWGs can be timely in saving lives and
improving sanitary conditions
• Disaster management organisations specify drinking
water as a top priority to maintain good health
Portability, reliability of AWGs in generating pure drinking water will prove
to be a vital technological intervention in sustaining lives and health

15. BENEFITS OF AWG
1
• Highly portable, economical and easy to maintain
2
• No expensive piping infrastructure investment is needed
3
• Easy installation
4
• No conventional water source required
5
• Needs only to plug into electrical socket to generate fresh, pure water
6
• Convenient, dependable, and safe
7
• Gives you total control over your water needs

18. 3 KEY TAKEAWAYS
Despite widespread water
pollution and shortages of
drinking water, there is an
abundance of water around us
Water harvesting generators are
the most environmentally friendly
way to extract pure quality water
from the air at a low cost
With emerging technologies,
AWGs are now commercially
available and mostly scalable
depending on need and location
