Need for water-from-air technologies stated by University of Illinois researchers

​Peer-reviewed articles, even about water resources, can be a dry read. But not so for the recently published Open Access article, Increasing freshwater supply to sustainably address global water security at scale. Let me share four excerpts from the paper to inspire and energize us in the water-from-air community. The excerpts show we do indeed have a crucial role in improving access to drinking water.

- "...reducing and managing [water] demand are proving inadequate as population and economic growth quickly absorb any capacity that is created through these measures."
- "Recycling and reuse of water...have limited scalability because they are fundamentally constrained by the available supply."
- "Effective solutions to increase the [fresh water] supply are at present limited, or they are practically non-existent since all resources are being exploited beyond sustainable capacity or rapidly dwindling due to climate change."
- "Desalination is not only energy intensive; it also creates concentrated brine and other byproducts that create significant environmental challenges with the cost of disposal."


The authors proceed to outline their proposal for a system for siting water vapor collection systems above the surface of the ocean and then transporting the vapor to condensation systems on the nearby shore. They discuss the water vapor resource, the insignificant impact of climate change on viability of their system, the negligible environmental impact, and the financial feasibility. The research trio also claim their ocean-based system will benefit from a higher moisture flux compared to land-based water-from-air installations.

The merits of the system outlined in the article remain to be validated but the important learnings from the article for those of us in the water-from-air industry are the quotations about the continuing inability of conventional water resources to provide global water security---thus giving incentive to our industry leadership to continue working diligently to prove the value of developing and commercializing water-from-air technologies.

Atmospheric water generators could be a gap-filler for California's water supply strategy

California's Water Supply Strategy (19-page document; click on the image above to read it) was published in August 2022. The strategy includes:
  • Storm water storage
  • Recycling and reuse
  • Efficiency of use and conservation
  • Desalination
  • Modernization of water systems
  • Improving water management (data, forecasting, administration of water rights)
  • Groundwater recharge expansion
  • Reservoir expansions
  • Dam rehabilitations
  • Demand reduction
  • Groundwater supply stabilization
  • Improve flexibility of water transportation
The use of atmospheric water generators (AWGs) is not mentioned in the document. But, AWGs can be effective drinking water supply gap-fillers in site-specific situations. Examples include:
  • off-grid residential or commercial applications,
  • high quality water for beverage or food manufacturing,
  • retrofitting water dispensers into buildings lacking sufficient plumbing infrastructure, and
  • alternative to bottled water coolers in homes, offices, and factories.

Intriguingly, the Strategy document says, "Rising temperatures evaporate more water, but more of that water stays in the air." (page 1 of 16). AWG's can recover that sequestered water.

The knowledge-base for using atmospheric water generators in California includes:
  • Product information from AWG suppliers, some based in California,
  • Atlas of the Water-from-Air Resource for California,
  • Water-from-Air Hourly Model Report for Watsonville, California, USA, and
  • Water-from-Air Resource Charts: California.

#Mauritius #Water from Air Resource

16/1/2013

0 Comments

 
A news item about the company, Water Resources Group, expanding, "its licence relationship with Mandala Water to include The Republic of Mauritius,..." for desalination plants prompted me to produce a water-from-air resource chart for Port Louis, Mauritius. Annually, water vapour density ranges from a high of 20.4 grams per cubic metre in February to a low of 13.5 grams per cubic metre in July and August. Conditions are excellent for water-from-air production from November to May. Conditions are rated "good" for atmospheric water generator operation during the balance of the year. Details are available in the Port Louis chart.

Recent legislation in Mauritius demands hotels and "major hospitality centres" have desalination plants. Could water-from-air systems be considered as an alternative to desalination plants at some sites?

Quantifying interest in water-from-air and associated topics

10/4/2012

0 Comments

 
How much interest is there in water-from-air technology? Wikipedia provides page view statistics for its articles. These statistics provided a crude estimate of interest from the English-reading, Internet-using public. Here is the table I assembled, with twenty-eight Wikipedia articles listed in order of page views in the last 30 days as of April 10, 2012. I started with the reference list in the Atmospheric water generator article. As I went from one referenced article to the other a point was reached when no new relevant references were found.

The hierarchy of public interest in these related topics was made evident. The water cycle must be a popular topic in schools!

The article Atmospheric water generator, with 4178 page views was of most interest because that terminology has become widely used to describe commercial machines that produce drinking water from the ambient air. The article, Desalination, had a much higher profile, attracting 10 times as many page views. For those of us seeking to raise the profile of water-from-air technology---we have a lot of work to do given only 100 to 150 people viewed the AWG article each day. How many read it is another matter!

(By the way, I have not been a contributor to Wikipedia articles.)

    I have been researching and developing drinking-water-from-air technologies since 1984. As a physical geographer, I strive to contribute an accurate, scientific point-of-view to the field.
