  1. 1. Atmospheric Water Harvesting - Yuvan kumar
  2. 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. 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. 4. DID YOU KNOW? One billion people worldwide live without clean, safe drinking water Two billion live without basic sanitation
  5. 5. So, how do you make sure they get pure drinking water that satisfies all their basic needs at low environmental impact?
  6. 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. 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. 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. 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 1 2 3 4

  12. 12. WORKING OF AWG
  13. 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. 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. 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
  16. 16. STRENGTHS OF AWG
  17. 17. WEAKNESSES OF AWG
  18. 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
